Triton Stabiliser Valve And Solenoid Assembly P12120800

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

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

If it is just a case of no water then you can get away with just replacing the coil however id there any other problems such as not shutting down or dripping then you need to replace the valve.

The solenoid is a push fit into the stab valve.

It is more likely that it is the stab valve that is leaking and the water is seeping down the back on to the solenoid stab valve joint.

Yes it is the complete assembly that will need replaced.

Could it have been frozen?

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 is not 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.

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
