NO HOT WATER IN SHOWER
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 the problem is traced tothe shower then you will need a new cartridge, however it may be worth whilestripping the cartridge out and making sure that the filters are clean andclear before ordering a new cartridge.
