Water still keeps running after main switch is turned off.

I changed to protentioner on my mira vigour thermostatic. Now when i turn off power water keeps running on gravity feed even though the pump is turned off. How can this be fixed. ?

It may be your solenoid valve, you can check it if you have a multi meter, you should have a reading of at least k3.5 ohms, across the two terminals any less and you need a new valve. (Check the valve in the failed state.) (When it has stopped working!)

If there is power getting to the solenoid and it is not operating then there is a good chance that you have a faulty solenoid.

The video is intended as a guide and does not cover every shower.

If you don’t have a multimeter we sell them with a guide on how to use them for checking and testing the various parts of your shower.

Apart from helping to fix your shower, they are really useful for checking you have a power supply to appliances, for checking fuses and letting you know much power you have left in batteries

(So you will know if they are good or not) and lots of other jobs, in short they are well worth a few pounds

If when you switch off the shower at the main isolator and the shower keeps running then you have a faulty solenoid valve.

When you switch off the shower at the main isolator and the water stops running, then you have a faulty on/off switch or a faulty PCB or a micro switch that is sticking on.
