OK.... but its been fine for 8 years and over the last couple of months the shower has been erratic. The boiler is about 11 years old..... Can anyone give me any tests to do so that I can pinpoint whether it is the thermostatic cartridge that needs replacing. Its a Bristan shower. Thanks all
Well the hot taps are fine in the bath and the basin once they run hot, takes a minute or so. The pressure is OK not brilliant in the bath. Just odd that when I turned on the hot tap (to a trickle) and the cold tap ( te reliev the pressure) in the basin the shower went really hot and then cold...
My shower keeps going cold and I want to know whether I need to buy a new thermostat cartridge or if its the boiler. I will tell you more.
Rose not scaled up and pressure good. Still cold though when I take the rose off
Hot water in all taps in bathroom. Shower gets warm if hot tap in sink...
My boiler does not fire up when I turn my shower on. All other hot taps work fine in the bathroom just the shower! Is is a boiler problem or it is that I need a new thermostat in the shower? All filter ok and rose not scaled up. Its a Vaillant boiler - combicompact GB242E
Also how do I...
