Basic installation steps 

  1. Prior to installation ensure that you are following applicable plumbing and electrical guidelines in your city or state/province and that your plumbing configuration is protected against backflow and cross connection maintaining the safety of the public water supply.
  2. Position the Hydraloop device in its planned location.
  3. Connect H300 1.5 wastewater outlet to sewer.
  4. Connect incoming greywater to the inlet on the top of the device via inlet manifold, in combination with external lift pump if necessary.
  5. Connect H300 1.5 reusable water outlet connections.
  6. Connect the backup water supply and open.
  7. Plug 100/240V power cord into wall socket.
  8. Run the Testing, Verification and Activation using the HDM with your Hydraloop Sales Engineer.


The H300 1.5 device is to be installed against the wall, leaving room for the electrical connection. The device must be secured to the wall to protect against falling over.  The top plate comes equipped with a mounting hole for fastening to the wall.

Hook the mounting hole of the H300 1.5 top plate onto the square shoulder hook, which is drilled and fasten into the wall, so the Hydraloop device is fixed to the wall and protected against falling over.


To remove the stainless-steel front plate, use a lever on the lower side of the front plate to carefully lift the stainless plate upwards. The plate is holding its position due to its shape so once it moves upwards it will be free to remove. Disconnect the LED light connection from the front plate and put the plate aside. 

  1. Carefully wedge a wooden (broom stick handle) or plastic tool between the bottom of the front plate and the floor and move the front plate upwards.
  2. Remove the front plate off the device.
  3. Disconnect the earth wire and LED light connection (Premium model) from the top of the front plate being careful not to break the wire connection.
  4. *Place the front plate in a way that the front plate cannot fall and be damaged.

  2. Greywater inlet
  3. Incoming water sensor
  4. Incoming water sensor
  5. Ventilation valve

Install the H300 1.5 inlet manifold as follows:  #

1.    Take the grey inlet manifold (40 mm/1 1/2” OD), and carefully install it into the top inlet of the T1 tank.
2.    The supplied blue rubber plug needs to be slid over the grey inlet pipe to just below the first elbow of the pipe.
3.    Lubricant (Vaseline) must be applied to the blue rubber plug and the T1 tank inlet.
4.    The inlet pipe can then be pushed all the way into the T1 tank, ensuring a watertight seal is made.  The pipework inlet should now be facing the back wall.
5.    Using lubrication, the 12 mm | 15/32” grey air pipe can then be connected to the grommet on the ventilation valve elbow of the inlet manifold.
6.    The solid blue and see-through blue air pressure sensors can be connected to the appropriate sensor ports on the top of the inlet manifold.
7.    You can now connect the greywater feed line from Recycle Ready 3-way valve to the manifold inlet.
8.    Once all the above steps are complete, please ensure that all pipes and connections are watertight and secure with no leaks.


The Hydraloop device comes equipped with two standard outlet valves, (1) dedicated for feeding multiple toilets (no high flush toilets) and (1) dedicated for feeding one washing machine. There is also an optional auxiliary outlet valve that can be added to feed the garden/pool.

Note that the irrigation valve will not be permanently pressurized.  Unlike the other two reusable water outlets, this outlet’s standard function is to supply reusable water when a surplus is available.  

Note the outlet connections on the Hydraloop device in the drawings below:

The Hydraloop device requires a minimum of 21 days (3 weeks) and 20 showers to develop the biological treatment process in the T2 tanks and become fully operational. The greywater treatment will start from the initial start-up; however, this reusable water will be purged into the sewer and the backup water will be supplied instead. After this start-up period of 21 days (3 weeks) and 20 showers, the Hydraloop device will automatically switch over to deliver reusable water to the toilets, washing machine and/or auxiliary outlet.


If there is not enough reusable water available, the device will automatically switch to backup water. The device is connected to its backup water supply via an air gap to protect the tap water against backflow or cross contamination. Additionally, a non-return valve is mounted on the point of incoming backup water. NOTE: If using rainwater as a backup water supply pretreatment must be applied prior to entering the Hydraloop device.  Pretreatment should include a 5-micron filter and carbon filtration, UV disinfection, expansion vessel and a pressure regulator (depending on the booster pump). The incoming flowrate should not exceed 12 lpm | 3.2 gpm, 1.5-3 bar | 21.75 – 43.5 psi.


During periods of unscheduled maintenance, service, or power failure it might be possible that supply of reusable water backup water is temporarily not available. To overcome this a bypass option can be installed. The bypass setup must comply with the applicable regulations of the country, state, or municipality.  


The Hydraloop device is extremely reliable, and all critical components are monitored continuously by our server through a permanent Wi-Fi internet connection. In the unlikely event a component fails (i.e., the UV lamp) the device will automatically switch to backup water, and everything in-house will function as usual, with no reusable water being distributed as a precaution. An automated system warning will appear on the HDM and Hydraloop APP.


Hydraloop device is designed for ‘normal usage’ and is not designed to receive solid materials like stones, chemicals, paint residues, hair dye, bleach, disinfectants, or any other matter that is unusual for shower/bath and washing machine greywater. In the event these substances enter the H300 1.5, it can be damaged, and the water treatment can be affected. There is a function in the APP where the greywater from the T1 tank can be wasted to the sewer if you suspect foreign matter has entered the Hydraloop device (i.e., hair dye or bleach).

Note: Hydraloop Systems BV is not liable for any damage if the above or any other abnormal substances enter the H300 1.5.


Under this Factory Warranty (“Warranty”) Hydraloop warrants to the first and original purchaser of the Hydraloop device set forth in Part 1 of the Warranty Policy under “Customer”, such product hereinafter referred to as the “Product”, that such Product shall be free from material Defects for a period of two (2) years as of the date of the original purchase invoice from Hydraloop or one of its authorized Partners, unless local jurisdiction requires a longer term. “Defect” as used in these warranty terms means a manufacturing or a design defect that materially impinges on the use of the Product and which is solely attributable to Hydraloop and that was not detectible at the time of delivery of the Product or part of the Product.
