I fitted a new thermo shower valve about 2 years ago but I now have a problem with it.
There is no hot water coming through.
The power pump is working ok.
The hot water is getting as far as the valve itself - (pipes are hot up to the valve)
I suspect that it is the thermostat itself inside the mixer valve that has stopped working.
Is it possible to open these valves for maintenance and is the thermostat part replaceable?
Can anybody suggest how I can test the thermostat or suggest any other cause for this before I pay out for a new valve?
