Shower - hot and cold

[xAlex]

Hallo all.

I had a simple message from a mate which can be summarised: "shower running hot and cold".

Pressure is not the issue. I do not have any technical information, but can you just advise if there is a 'usual' fault resulting in these symptoms. I am guessing that the power to the shower cuts out, without the water reaching the normal thermal cut-out temperature, meaning that cold water is produced for a few seconds. Problem is intermittent.

thanks.

Thermostat. Are you sure about the pressure? That's the top two of my list.

...well, the shower worked for a long time, then the fault developed, without any apparent pressure reduction.
