When i am in the shower the water keeps going hot and cold. This has only started happening since i have had two new radiators fitted. The radiators are not a problem as they heat up as they should.
don't blame the poor bloke who has done the radiators. Check main cold water pressure, sounds like it could be high, this causes havoc with shower valves and boilers, they are only designed to cope with about 5 bar pressure max but that is still high, a pressure reducing valve PRV can be fitted to control the pressure usually factory set at 3 bar but better to reduce it further to about 2 if not detrimantal to other things in the house. Also could be your thermostat in the shower valve going funny
