I have got a comb boiler and Prism Thermostatic Recessed Shower.
Recently the hot water is not hot any more but the boiler is working fine.
It's been also noticed that the hot water flow faster than before. A friend checked my water system and he said there was some wrong with the shower control part. The cold water flow into hot water pipe, because the part of hot water pipe in ground floor is still warm even hot. He didn't say which part exactly was faulty.
I barely know anything about plumbing, and I checked the fitting instruction and I found a part called non return valve, I guess (only guess from the name), whether it is this so called non return valve is not working properly, and cause cold water flow into hot water pipe?
I found the store where sell spare parts, but I am not sure exactly which part is faulty, anyone can help me out of this please?
