trevi trad no. 311 only luke warm

Our shower worked great until we changed from Oil to a gas combi Boiler. The shower is now only luke warm but the pressure is very good. The plumber has said we need a new Therm control cartridge. The shower is approx. 10 years old We only have one bathroom in the house and the boiler is more than big enough to cope. Don't wont to spent £140 if we don't need to. Cheers for any help

Regarding the temperaturefluctuation or cool running it could be a faulty cartridge however to checkthis, see if you can get hold of the hot supply pipe before it enters theshower or perhaps as it leaves the boiler.

If when holding this pipethe temperature fluctuates or goes cool then the problem is not with the showerbut more likely with the boiler as the shower can only deliver what the boilersends to it.

Disregard the temperature atthe taps as they have a different flow rate.

If you trace the fault tothe cartridge then it may be worth removing it and checking that the filters areclean before ordering a new cartridge.
