When the toilet output or washing machine output are not being pressurized for an unusual amount of time, a warning is made. The cause of this can vary widely.
How is the toilet/washing machine being pressurized?
The Hydraloop keeps the pipework of the toilet and the washing machine under pressure with a water pump. This pump we call the distribution pump. This pressure is hold by what we call a ‘check valve’. Which only allows water to flow into the pipework. But not back into the Hydraloop. When a toilet is flushed, this pressure is dropped and measured by our pressure sensors inside the pipework.
When anything is wrong with this process the pipework can not be fully pressurized. This can mean that no water is flowing at al. Or something makes it too difficult for the distribution pump to put enough pressure in the pipework for the sensors to give feedback that the Hydraloop can stop pumping (e.g. constant leaking water from a toilet).
Just installed a new system with this problem? #
In case you just installed a new system. It could be that a small miscommunication on the installation requirements can be the cause. If you are using a ‘Storage tank’ after the Hydraloop please make sure to install the hose to the ‘Auxiliary’ output instead of the toilet (WC) outlet. Otherwise you will have the distribution pump constantly pumping water in the tank forever. As toilets always need to be filled, it will also use backup water to keep pumping to the toilet (WC) outlet. See below diagram to understand toilet outlet and washing machine outlet versus the auxiliary outlet.

Causes #
The causes for not enough pressure in the pipework can vary a lot. Almost always the Hydraloop has done its own testing to pinpoint the problem. As this is still a work in progress, we are going to give general instructions and examples here to look into the problem.
How to identify the cause
- Use the link of the ticket that is generated that will bring you to the start of the problem in the “Graph” view.
- Here you will find a lot of info. On the ‘Toilet’ or ‘Distribution pump’ timeline it will be possible to click/touch this timeline. A small outline makes this clear that it is clickable.
- It will display more details of the problem when you click it.
- See the ‘example cause’ below how this interface would look like.
Example cause: no backup water
In below example no backup water is available. For this reason the ticket got created. See the first image how we know.
To then check if this problem is still going on, go check the timeline to ‘live’ (see last image red circle). Then check again.
In this example on the last image at the orange question mark you see nothing anymore. So the problem has already been resolved. The ticket can be closed.
