My power shower pump serves two showers. One works fine but the other keeps cutting out for a few seconds, restarting then cutting out again.
I've checked the pipework, hose and showerhead and they seem fine, so only thing I can think of is the mixer. It's an old Grohe Grohtherm 100 concealed.
Is it likely to be the thermostatic valve or the flow control? How do I test?
