Hi there, I had a shower fitted about 18 months ago,its worked fine until now.but last week when I went to use it a red light came on saying low pressure, the water comes through fine but it flicks from hot to cold every 5 secs,, is there anything I can do myself to fix this or am I going to have to pay out for someone to fix it..?

Where is this red light, is it on your water heater?

It sounds like you have a power shower. I don't know about the other experts but when I see one of those I run for the hills. Each one is different. Perhaps one of the other experts has a handle on this but if it were mine I'd be calling the factory service man to take a look at it. Sorry I couldn't be more helpful, Tom

Tom, those foots steps you hear behind you is me running for those same hills.
