Frequently Asked Questions

1. Water details

What is greywater?

Greywater is the lightly contaminated wastewater from bath, shower, and optionally from hand basins, and washing machines. Greywater should not be confused with blackwater. Blackwater is the wastewater from toilets, kitchen sinks, floor drains, and dishwashers.

Apart from greywater, some Hydraloop devices can also treat the condensation water from air conditioning units, tumble dryers, and heat pumps.

What is Hydraloop reuse water?

Reuse water is greywater that has been treated in a Hydraloop device. It can be reused for non-potable water needs like toilet flushing, washing machines and/or outdoor uses.

Is the treated water from a Hydraloop device safe for reuse?

Yes. Hydraloop reuse water is clean, clear and disinfected. The treatment technology has been tested and certified under the NSF-350 protocol and meets the most stringent international standards. Hydraloop reuse water should not be used for drinking, cooking or personal hygiene. That means: do not use Hydraloop reuse water in your kitchen, shower, bath, hand basin, bidet and/or hand shower.

Can I drink the reuse water from a Hydraloop device?

No. A Hydraloop device does not produce potable water.

What can I use the reuse water from a Hydraloop device for?

The reuse water from a Hydraloop device is suitable for toilet flushing, washing machines, garden irrigation, topping up swimming pools and cleaning purposes.

Can I use the reuse water from a Hydraloop device in my bathroom?

Can a Hydraloop device treat greywater that contains a lot of calcium? Can a Hydraloop device handle hard water?

Yes. Hydraloop devices can treat greywater with any hardness. If your tap water contains a lot of calcium, we recommend descaling your Hydraloop device every six months with 500 cl (1 pound) of citric acid. For information on descaling, please check the Hydraloop App.

2. Certification

Do greywater recycling devices need certification?

Yes. Third party certification is important to ensure the water quality, electrical safety and performance of any greywater recycling device. The level and type of certification you need depend on local plumbing codes and regulations. By installing a third party certified Hydraloop device, you can be reassured that it will deliver safe reuse water for non-potable use.

Are Hydraloop devices certified?

Yes. All Hydraloop devices are certified by the highest international standards for greywater quality and electrical safety.

What is NSF-350?

NSF is an American organization with worldwide recognition for their third party testing on water treatment products. The NSF-350 standard establishes material, design, construction and performance requirements for onsite residential and commercial water reuse treatment systems. It also sets water quality requirements for the reduction of chemical and microbiological contaminants for non-potable water use.

NSF-350 ExplainedNSF-350 Explained

NSF-350 – Onsite residential and commercial water reuse systems

Point Form Explanation:

For treatment components to be regarded as ‘safe’ to use, they must have undergone some type of ‘third party testing’.
The third party will take specific equipment (UV disinfection systems, inline filters, greywater treatment systems), test them under specific conditions, and sign off stating ‘This system or component does perform the way the specific NSF standard outlines’.
NSF is a third party that validates treatment components or equipment and gives it their ‘stamp of approval'. The NSF (National Sanitation Foundation) seal of approval is recognized worldwide.

NSF-350 is specifically written for greywater treatment equipment.
When testing a greywater recycling device, NSF sets up the device as it would be installed in a real-life installation.
The influent water during the test has the characteristics of greywater in a typical home.
From the results of the test, NSF determines if a greywater recycling device delivers reusable water that is what NSF deems safe to reuse for toilet flushing, washing machine use and/or outdoor use.
A NSF-350 tests takes 26 weeks to mimic the real life installation of a greywater recycling device.
The testing period focuses on water quality and on the loading of the greywater recycling device; this is called stress testing and includes the introduction of elevated levels of components like soap to the device.
The concentration of greywater from showers, baths and washing machines is well documented and NSF has produced the list of characteristics and their concentrations that greywater treatment systems must meet.

Greywater typically has high concentrations of the following:

TSS: total suspended solids – this is a measure of suspended solids in a sample and the concentration (ppm) provides the weight of particulate material that is present in the water. This parameter would assist in determining what kind of load of particulate would be collected from water. For example, if there is a high TSS concentration you would know that the load on the filters would be high and therefore the filters would need to be changed more frequently.
Turbidity: The cloudiness or haziness of a fluid due to particles visible to the naked eye – turbidity and TSS are essentially the same parameter, but turbidity is more a measure of how well light can pass through a sample whereas TSS is more of a quantitative expression of suspended particles. Typically, turbidity is a concern when you are incorporating a UV system. Turbidity is visible to the naked eye, microorganisms are not. Consider how many microorganisms can attach themselves to a piece of turbidity and can be shielded when passing by a UV light thereby getting through to the treated water. All turbidity must be removed from the water prior to a UV system. The level of turbidity will assist in determining the size of filter you need. An elevated level of turbidity (say 10 NTUs) will need a 20-micron filter to remove it whereas a turbidity of say 2 NTUs will only need a 5-micron filter.

BOD: Biological Oxygen Demand – Higher BOD indicates more oxygen is required, which is less for oxygen-demanding species to feed on and signifies lower water quality. And a low BOD means less oxygen is being removed from water, so water is generally more pure. BOD is a biological oxidation & is performed by aerobic organisms (organisms that thrive when oxygen is present).

COD: Chemical Oxygen Demand – The oxygen demand that is consumed by both organic and inorganic matter present in a sample. COD measures the oxygen required to decompose organic and inorganic constituents present in a sample by a chemical reaction. If there is a 'high demand' for oxygen that indicates that there is something in the water depleting, it which is detrimental to the condition of the effluent. COD is a chemical oxidation process performed by chemical reagents in the sample.
Total coliforms: this is a group of bacteria that are not bad for you (non-pathogenic) - this is called an indicator group. If there is a high level of total coliform then you need to determine what makes this number high by testing for more specific, pathogenic bacteria.
E.coli: pathogenic bacteria that indicates that the sample has been exposed to mammal waste. If you have a high total coliform count this usually is an indicator that there is E.coli present.

3. How Hydraloop works

How does a Hydraloop device clean greywater for reuse?

The Hydraloop device uses a unique combination of sustainable water treatment technologies that ensures the highest water quality.

Hydraloop’s patented technology is consumer friendly, carefree and sustainable. The treatment process removes hair, dirt, soap and other pollution from greywater without the use of filters, membranes, or chemicals, so there is no need to clean and/or exchange filters. This substantially reduces the operational costs.

The Hydraloop greywater treatment combines six technologies: sedimentation, flotation, dissolved air flotation, foam fractionation, an aerobic bioreactor, and disinfection of the treated water with powerful UV light, inactivating all pathogenic microorganisms.

All Hydraloop devices are self-cleaning and low maintenance. Depending on model, water hardness and user behaviour, we advise a service and maintenance check-up every 6, 12 or 24 months. Your Hydraloop installer will advise you on the best schedule for your installation.

How long does the treatment process take?

The treatment takes approximately 5-6 hours. The bulk of greywater is collected during showering, which typically takes place in the mornings and evenings. With two treatment cycles daily, there is enough treated water for non-potable reuse.

What is the difference between the Hydraloop models?

The main difference between the Hydraloop H300, H600, Hydraloop Concealed and a Hydraloop Cascade is the size of the device and its recycling capacity.

The H300 is ideal for single family homes with 4-6 people. The H600 is suitable for single family homes with higher water usage and for small businesses like office buildings, gyms and boutique hotels. The Hydraloop Concealed is ideal for individuals and couples and can be integrated in bathrooms for apartments, small homes and tiny houses. Hydraloop Cascade installations are modular, scalable and made-to-measure. They are used in multi-family homes and larger commercial real estate like hotels, student housing, sports clubs and more.

How do I know which Hydraloop device I need?

This depends on the size of the building and the amount of people using water in the space. Your Hydraloop installation partner will make a detailed calculation to advise you on the most efficient setup for your project.

Do different Hydraloop models have different power requirements?

No. Power requirements of Hydraloop models are different depending on your geographic location. However, the power consumption of your device will not change regardless of the voltage.

What is the power consumption of each of the Hydraloop models?

H300: 220 kWh per year, 25W on average during treatment.

H600: 460 kWh per year, 53W on average during treatment.

Hydraloop Concealed: 180 kWh per year, 17W during treatment.

A Hydraloop Cascade is modular and made to measure, so power consumption depends on the model and number of devices.

Do Hydraloop devices make a sound?

In standby mode and during greywater treatment, Hydraloop devices produce a sound of approximately 44 db, comparable with the sound of a silent dishwasher. During the treatment process, you can hear the sound of the dissolved air flotation (air bubbles) in the device and briefly the sound of the water pump in action.

What happens when too much water enters the Hydraloop device?

When too much greywater enters the device, it will automatically discharge the additional water to the wastewater outlet.

4. Prepare your building

What kind of buildings can Hydraloop devices be installed in (new build, retrofit)?

Many stand alone devices are installed in new builds, but Hydraloop devices can also be installed in retrofit projects.
Any building suitable for the installation of a Hydraloop device needs a double piping network for the collection of lightly contaminated greywater and the distribution of Hydraloop treated reuse water.

In new builds, the setup of a double piping network is easy and cost effective. In an existing bulding, the costs for setting up a double piping network will vary depending on the structure of the building. Your contractor can design the plumbing layout according to the guidelines in the Hydraloop Recycle Ready Guide.

Can a Hydraloop device be installed outside?

No. A Hydraloop device cannot be installed outside. It needs to be protected against the weather and direct sunlight. The ambient air temperature should be in the range of between 14-35 degrees Celsius or 57-95 degrees Fahrenheit.

Where in the building can a Hydraloop device be installed?

Hydraloop devices can be installed in basements, laundry rooms, heated garages or technical rooms. Every Hydraloop device must be installed indoors and the ambient air temperature should be in the range of between 14-35 degrees Celsius or 57-95 degrees Fahrenheit.

Depending on the location, a lift pump can be required. For example, if the Hydraloop device is installed on a higher floor than your washing machine, you will need to have a lift pump to lift the greywater up to the device.

What should the installation space of a Hydraloop device look like?

The greywater inlet and inlet diverter should be positioned at least 2.2 m | 87” above the ground.
Room temperature should be between 14-35 degrees Celcius | 57-95 degrees Fahrenheit. Extreme high or low temperatures should be avoided.
Avoid direct sunlight on the Hydraloop device. It is not IP rated or UV resistant.
Hydraloop recommends installing the device in a laundry room, mechanical room, or garage.
Allow at least 60 cm | 24” of space in front of the Hydraloop device face plate for maintenance access. The H600 has two sides that should be accessible for maintenance.
Hydraloop device height requirements allowing for plumbing, installation & maintenance access: FFL (Finished Floor Level) to bottom of grey water inlet pipe: 2.2 m | 87”. FFL to FCL (Finished Ceiling Level): 2.3 m | 90.5” .

Why do Hydraloop H300 devices not treat water from hand basins or condensation water from air conditioning units, tumble dryers and heat pumps?

In most family homes, the bulk of greywater is collected during showering. The amount of greywater collected from hand basins and condensation water is relatively smaller in comparison.

The Hydraloop H300 device collects all incoming greywater in one tank. 15 minutes after greywater has entered the device, the treatment process starts. When new greywater enters the Hydraloop device, a treatment process is interrupted and starts over.

The Hydraloop H600 device has two tanks. During the treatment process in tank 1, the device collects incoming greywater in tank 2. This does not interrupt the treatment process in tank 1.

Can Hydraloop recycle greywater from hand basins?

A Hydraloop H600 device can treat greywater from the hand basins (not from the kitchen sink). A Hydraloop H300 device cannot treat greywater from the hand basins (not from the kitchen sink).

What happens when no reuse water is available?

When a Hydraloop device has utillized all reuse water in the tank, the device will automatically switch to backup water. Backup water is usually tap water. As soon as new reuse water is available, the Hydraloop device will automatically switch back to reuse water to supply your non-potable sources.

What happens when I go away for a few days?

When no greywater flows into the device for 72 hours, it will automatically switch to ‘holiday mode’. Once you start using water again and greywater is produced, the device will automatically restart water treatment.

What happens when I go away for a longer period?

When you go away for more than 3 weeks, the Hydraloop device will automatically empty all the reuse water from the tanks. Once you start using water again and greywater is produced, the device will automatically restart water treatment. Do not turn off the Hydraloop device during your absence. Power consumption will be very small.

How many toilets can be connected to a Hydraloop device?

A stand alone Hydraloop H300 or H600 device can feed up to four (4) toilets at a maximum distance of 20 meters wide and 12 meters high. Cascade systems can be equipped with an external booster pump to extend the range and number of toilets.

Can more than one washing machines be connected to a Hydraloop device?

A stand alone Hydraloop device can be connected to no more than one (1) washing machine.

What is the warranty on Hydraloop devices?

The warranty period for a Hydraloop device is specified in the Warranty Certificate for a period of two years on specific components. The Certificate may vary according to national law.

Are you interested in a longer warrenty period? Selected Hydraloop partners offer Hydraloop Care, extending the warranty on all components to 5 years or longer. Hydraloop Care can be extended to 20 years. For more information, please contact support@hydraloop.com.

What is the lifespan of a Hydraloop device?

Hydraloop devices have been designed to last for at least 20 years.

What is the volume of the H300 device?

The H300 device can hold a maximum volume of 300 liters | 80 gallons of water. The upper tank (water treatment tank) holds 180 liters | 40 gallons of water. The lower tank (reuse water tank) holds 120 liters | 26 gallons of water.

What is the volume of the H600 device?

The H600 device can hold a maximum volume of 600 liters | 160 gallons of water. The upper tanks (water treatment tanks) hold 360 liter | 80 gallons of water. The lower tanks (reuse water tanks) hold 240 liters | 52 gallons of water.

What is the volume of the Hydraloop Concealed?

The Hydraloop Concealed can hold a maximum volume of 150 liters | 40 gallons of water.

What is the volume of reuse water that a Hydraloop device can produce per day?

The volume of reuse water depends on different factors. How many people are in the building, how much water do they use, and how effectively do they use the water. The Hydraloop App provides live numbers on the amount of treated reuse water in the building. It also gives recommendations how to utilize the treated reuse water in the most effective way.

For example: A family of five people lives in a home with a Hydraloop H300 device. Each family member takes one shower per day and uses the toilet 4 to 5 times per day. Three people shower in the morning, two people shower in the evening. The Hydraloop device provides two water treatment cycles per day, producing enough reuse water for toilet flushing and garden irrigation. The Hydraloop App will recommend to use the washingmachine in the afternoon, when the first treatment cycle is finished and the water reuse tank is full.

Does a Hydraloop device require a wall power outlet? Does a Hydraloop device need electricity?

Yes. The wall power outlet must have earth safety protection and should preferably be positioned above or next to the device.

What is the weight of a Hydraloop device?

A Hydraloop H300 device has a dry weight of 82,5 kg | 181.91 pounds. Filled with water, it has a maximum weight of 383 kg | 844.52 pounds. Before installation, make sure the floor can carry a minimum of 800 kilograms per m2.

A Hydraloop H600 device has a dry weight of 128 kg | 282.24 pounds. Filled with water, it has a maximum weight of 739.5 kg | 1630.60 pounds. Before installation, make sure the floor can carry a minimum of 1,000 kilograms per m2.

How do I prepare the building for the installation of a Hydraloop device?

Before installation of a Hydraloop device, you need to follow the guidelines in the Recycle Ready Guide provided by Hydraloop. In this guide, you will find plumbing diagrams, a connection overview, and all installation requirements to prepare the new build or retrofit. After preparation, both the Hydraloop owner and the plumber/contractor responsible for the preparation sign the Recycle Ready Checklist and submit it to the Hydraloop installation partner.

Hydraloop and its installation partners cannot proceed with installation and commissioning of a Hydraloop device if the preparation guidelines in the Recycle Ready Guide were not followed correctly and/or if the Recycle Ready Checklist has not been co-signed and submitted.

How is a Hydraloop device connected?

A Hydraloop device has three sorts of connections: input connections, power/network connections, and output connections. In the following diagram, you can see a schematic overview of these connections. Please do not use this connection overview for the preparation of the building, but refer to the installation requirements and technical drawings in the Recycle Ready Guide.

CONNECTION OVERVIEW

4. Installation

How is a Hydraloop device installed?

After the preparation of the building according to the instructions in the Recycle Ready Guide and submission of the Recycle Ready Checklist, your Hydraloop installer will install and commission the device. A Hydraloop device has three sorts of connections: input connections, power/network connections, and output connections.

Input connections: greywater lines from different sources to the inlet, and a backup water line (tap or rainwater) to the device.

Power and network connections: the device requires a standard power outlet and a permanent WiFi connection.

Output connections: seperate reuse water outlets to toilets, washing machine, and/or the garden or pool top-up, and a connection to the sewer.

How many outlet connections does a Hydraloop device have?

A Hydraloop device can have a maximum of 3 reuse water outlets. The first outlet feeds reuse water to the toilets, the second outlet can be connected to the washing machine and the third (optional) outlet can be used for the garden or pool top-up.

Is it difficult to disconnect a Hydraloop device?

No, but we do not recommend to disconnect your device.

To disconnect a Hydraloop device, you first turn off the backup water supply, second you disconnect the power and third, you disconnect all physical connections (input and output connections). If you want to keep using all water sources in the building, we recommend connecting the the greywater input line to the sewer and connecting the backup water line directly to all reuse water outlets.

Can I use a grease trap or grease interceptor to recycle greywater from my kitchen in a Hydraloop device?

No, you cannot. Hydraloop devices are not designed nor suitable to recycle kitchen greywater.

Even after passing a grease trap or grease interceptor, kitchen greywater is too dirty for greywater treatment in a Hydraloop device.

Can a Hydraloop device treat rainwater?

No, it cannot. The tank size of a Hydraloop device is designed for a daily input of shower/bath water. Rainwater can fall in large volumes and the storage capacity of the Hydraloop H300 and H600 tanks are not designed for these volumes.

Can I combine the reuse water from a Hydraloop device with a rainwater tank?

Yes, you can. Some Hydraloop owners use this combination and have brought down their tap water consumption from 150 liter per person per day to 15 liter per person per day.

A Hydraloop device can be connected to a rainwater system in two ways:

As a backup source for the Hydraloop device instead of tap water. In this case, the rainwater must be pre-treated with filtration and disinfection, since rainwater can come into contact with many different surfaces.
To transfer surplus reuse water into the rainwater tank.

Can a Hydraloop device replace a rainwater tank or reduce its size and costs?

When you have a Hydraloop device, you can choose a rainwater tank for irrigation only, because you are using the treated Hydraloop water for toilet flushing and the washing machine.

If you recycle more greywater than you use inside the building, the Hydraloop device can pump the surplus to a rainwater tank. This way, you add Hydraloop reuse water for garden irrigation.

We believe that rainwater should contribute to the hydrologic cycle. Rainwater should flow into the ground, not into the sewer. Using Hydraloop reuse water both inside and outside, and rainwater only outside, you are reusing water in the most sustainable way.

Can a Hydraloop device be installed in an existing building?

Yes. A Hydraloop device can be retrofitted to existing homes and apartments.

Any building suitable for the installation of a Hydraloop device needs a double piping network for the collection of lightly contaminated greywater and the distribution of Hydraloop treated reuse water. The costs for setting up this double piping network will vary depending on the structure of the building. Your contractor can design the plumbing layout according to the guidelines in the Hydraloop Recycle Ready Guide.

Can a Hydraloop device be installed in a new building?

Yes. A Hydraloop device can be installed in any new building if the plumbing is installed correctly.

Any building suitable for the installation of a Hydraloop device needs a double piping network for the collection of lightly contaminated greywater and the distribution of Hydraloop treated reuse water. The costs for setting up this double piping network will vary depending on the structure of the building. If done by design, this is easy and costs are neglectable. If done by design, this is easy and costs are neglectable. Your contractor can design the plumbing layout according to the guidelines in the Hydraloop Recycle Ready Guide.

Does a Hydraloop device require start-up time before it is operational?

Yes. All Hydraloop devices have a start-up time of 21 days, this is required by the NSF-350 standard. During this period, the Hydraloop device will supply backup water. After the startup period, the device automatically switches to reuse water.

Can I decide what I want to use the recycled greywater for? (i.e. toilets, laundry and garden)?

Yes. You can control your Hydraloop device with an app on your smartphone. In the app, choose Settings, and Priorities to change your priorities for greywater reuse at any time. For example, in summer you may decide using your reuse water in the garden, in winter for laundry.

Is it difficult to install a Hydraloop device?

No. A seasoned installer will manage the installation of a Hydraloop device with ease. The correct preparation of the building is the most important requirement for a succesful installation. Your contractor can design the plumbing layout according to the guidelines in the Hydraloop Recycle Ready Guide.

How long does it take to install a Hydraloop device?

If the building is prepared according to the guidelines in the Hydraloop Recycle Ready Guide, the installation and commissioning of a Hydraloop device will take less than 2 hours.

Can anyone install a Hydraloop device?

No. A Hydraloop device is a high-tech product and can only be installed by an accredited installer/plumber. If the device is not installed by an authorized Hydraloop installer, the warranty will not be applicable.

5. Online Connection

Where can I find the Hydraloop app?

The Hydraloop app is available in the Apple App Store and the Android Play Store.

What can I do with the Hydraloop app?

The App provides information about current and past water savings, the tank levels, and device status information. It also has shortcuts to FAQ's, manuals, and much more.

Why is my Hydraloop device connected to a central server?

All operational Hydraloop devices are connected to a central server for remote monitoring, remote service and online software updates.

Does a Hydraloop device always have to be online?

In principle, yes. Every operational Hydraloop device is connected to a central server. If your internet connection is not 100% stable, this is not a problem. Every Hydraloop device can function without an online server connection for a limited amount of time (up to seven days). You should, however, never turn the internet connection off.

What data does the central server monitor?

The central server monitors the status of each operational Hydraloop device (operational, holiday mode etc.), as well as tank levels, valve positions, pump settings and displaced water volumes over time.

How does Hydraloop guarantee that the central server is always online?

The Hydraloop central server runs at the premises of a qualified hosting provider with secured data protection and back up services.

How does the data exchange between a Hydraloop device and the central server work? Are my data safe?

Each operational Hydraloop device has a secure TCP connection with the central server. A device can only communicate with the central server if the server sends a specific signal. The device cannot communicate with other internet servers.

My Hydraloop device has been installed but the Hydraloop app is not showing available reuse water, why?

This can mean two things. 1: The Hydraloop device is still in the start-up phase and does not supply reuse water yet. 2: The Hydraloop app is not connected to the Hydraloop Server. In that case, re-install the app and reconnect it with your Hydraloop device. In the app, navigate to 'Scan/enter Hydraloop ID' and add your Hydraloop device.

Can I change the WiFi network?

Yes, you can. Before you change the WiFi network, please shut down the old WiFi signal. Then follow the steps in the app.

What happens if my internet connection is unstable or cut off?

Nothing happens, as long as the connection is restored within seven days. After seven days offline, a Hydraloop device will stop recycling greywater and switch to backup water. When the online connection is restored, the device will start recycling greywater again.

Is there a way to run my Hydraloop device without WiFi?

No. A Hydraloop device can only work with a permanent internet connection, in order to monitor the treatment process and to guarantee the water quality of the reuse water.

6. Usage and Maintenance

Do I need special cleaning products or laundry detergents?

No, you do not need to use special cleaning products or laundry detergents. The only requirement is that you use cleaning products and/or laundry detergents without bleach. This applies to all showers and baths as well as the washing machine that are/is connected to a Hydraloop device.

Can I use cleaning products containing bleach in the bathroom?

Yes, but if you want to use cleaning products containing bleach, you need to activate a temporary bypass in the Hydraloop app. This will temporarily redirect the incoming greywater directly to the sewer.

If you clean your shower or bath with a product that contains bleach without activating the bypass, the bioreactor is destroyed. You will need to restart the bioreactor with your Hydraloop app. The 'start-up procedure' takes 21 days.

How to activate a temporary bypass:

In the app, go to Settings and select button four. (Cleaning shower/bath)
In the popup screen, select confirm.
In the Settings menu, button four now switches to green, indicating that the bypass is working.
After cleaning, rinse well with plenty of tap water.
To stop the bypass, select the green button. The color switches back to white and the bypass is stopped.
If you do nothing, the bypass automatically switches off after six hours.

Can I use laundry detergents containing bleach in the washing machine?

This depends on your situation.
1. Your washing machine delivers greywater into the Hydraloop device and you use Hydraloop reuse water for laundry.
In this case, you can only use laundry detergents containing bleach in the washing machine if you use the Bypass option in your Hydraloop app. To do so:

How to activate a temporary bypass:

In the app, go to Settings and select button four. (Cleaning shower/bath)
In the popup screen, select confirm.
In the Settings menu, button four now switches to green, indicating that the bypass is working.
After cleaning, rinse well with plenty of tap water.
To stop the bypass, select the green button. The color switches back to white and the bypass is stopped.
If you do nothing, the bypass automatically switches off after six hours.

If you accidentally use bleach without selecting the Bypass option, the biological treatment in the Hydraloop device is affected. Then you need to restart the bioreactor with your Hydraloop app. The 'start-up procedure' takes 21 days.

2. Your washing machine does not deliver greywater into the Hydraloop device, but you do use Hydraloop reuse water for laundry.
You can use laundry detergents containing bleach in the washing machine, because the used laundry water flows into the sewer.

3. Your washing machine is not connected to the Hydraloop device for input or output water.
You can use laundry detergents containing bleach in the washing machine, because the used laundry water flows into the sewer.

Can I dye my hair in the shower?

Yes, but if you want to dye your hair in the shower, you need to use the Hydraloop app for temporary bypass. This will temporarily redirect the incoming greywater directly to the sewer.

If you do not activate the bypass, hair dye will flow into the Hydraloop device. It wil not destroy the bioreactor, but the reuse water will be colored and could impact the treatment process.

In the app, go to Settings and select button three. (Rinsing out hair dye)

How do I restart the bioreactor?

In the Hydraloop app, select ‘Start-up Procedure’. This will empty the tanks and restart the bioreactor inside the Hydraloop device. During the start-up period, the device will automatically switch to backup water. You can use the showers and baths like you always do. When the biological treatment is fully operational, the Hydraloop device will automatically start recycling greywater and offer reuse water again.

The ‘Start-up Procedure’ takes 21 days.

How often does a Hydraloop device need maintenance?

How long does a regular maintenance session take?

On average, a regular scheduled maintenance session takes approximately 1 hour.

Do I need to replace any components in the Hydraloop device?

No. As a Hydraloop owner you never need to replace any components. During scheduled maintenance sessions, some specific components will be replaced by your Hydraloop installer. These specific components are the UV lamp, the air pump, transfer tube or air diffuser. The air pump and UV lamps are replaced every two years.

How often is the UV light replaced?

The expected lifetime of the UV light is 3 years. We recommend scheduling a preventive maintenance check for your device by your Hydraloop installer every two years. During this check, the UV light bulb is exchanged.

How is hardness build-up in a Hydraloop device removed?

Descaling is part of the scheduled maintenance program. Your Hydraloop installer will insert citric acid in the shower drain, which enters the Hydraloop device. Then, the device runs an internal cleaning cycle, descaling all essential components.

Is it possible that treated reuse water and the backup water get mixed?

No there is no opportunity for these two water sources to cross. Each Hydraloop device has an embedded safe air-gap preventing the backflow of reuse water to the backup water connection.

How long can a Hydraloop device function without electricity?

If a Hydraloop device does not have electricity for more than 1 hour, it will empty the tanks to the sewer. Once the power is back on, the device continues its normal program.

How long is the start up time after a power outage?

The start up of a Hydraloop device will only take a few minutes.

Who do I contact for maintenance on my Hydraloop device?

Please contact your Hydraloop installer for maintenance assistance. If you don't know who your Hydraloop installer is, please contact Hydraloop directly at support@hydraloop.com. We will direct you to a local Hydraloop installer in your area.
