I have a triton power shower -
model number - 97200030
It is flowing constantly, even when the control knob is turned to off and has clicked off water still comes out of the shower. Which part do I need to fix it?
I have removed the solenoid valve and it is possible to blow air through it quite easily. Should this be possible or does this mean the seat is damaged/passing?
I think that you have answered your own question. If you can blow air through the valve when it's disconected from the power, then it's not working as it should, simples!
