Please turn the shower on and listen or feel for the pump starting. If the pump doesn’t turn on, please inspect the power to the pump. Check that the isolation switch for the pump is on. (See the fifth point below Pump isn’t turning on at all). For further assistance please contact our technical helpline on 0345 9090 912.

Inspect the tricuspid valve for wear. For a video instructing you how to inspect and change the Tricuspid valve, please click here. Please check the pipework for blockages or air leaks. For video assistance on how to check the pipework for issues, please click here. For further assistance please contact our technical helpline on 0345 9090 912.

In such instances it is very unlikely that there is an issue with the pump or transformer.  Please check for blockages.  Carrying out an external pipework test will confirm if a blockage exists within the pipework. Note: A common cause of this symptom would be a screw cap stuck in the pipework turning on its axis. If there are no blockages, please increase the pump speed settings on the transformer to match the flow of the shower.

If your pump doesn’t turn on, please inspect the power to the pump.  For video assistance for our Switch Connect kit please click here.

Disconnect the transformer signal/sensor wire from the flow switch(es) or external sensor(s) or electric shower. If the pump turns off then the switch/sensor/shower control mechanism is at fault and needs replaced. If the pump continues to run after 1 minute, then the transformer needs to be replaced. Please note that when a Venturi sensor is used, if it has not been earthed properly then this can cause the pump to run on.

Switch Connect Mixer System - This may be caused by fluctuations in the water pressure within the building. Fitting a non-return valve before the flow switches / flow sensors on a mixer shower will prevent this from happening.

Instant Match External Sensor/Digital Smoothflow/Dry-Deck Systems - This may be caused by fluctuations in the water pressure within the building. Fitting a non-return valve before the flow switches / flow sensors on a mixer shower will prevent this from happening. A bad earth to a Venturi sensor can also cause this to occur.
