Ongoing problem: I replaced 2 Bristan Pisa cartridges. One at top of house was fully successful & works properly.
On ground floor, shower produces tepid through to hot water. As I (sparingly) water the garden from here (attaching garden hose). this is a big cost issue. To (just about) keep plants alive, I have to use warm water.
Hot & cold feeds into shower are OK: hot one side, cold the other side, so the fault can't lie there.
So does the fault lie with settings on the cartridges ?? I've tried 3 variations: bought 2 new cartridges & tried them out, without altering any settings. Also tried out the old one (after soaking in vinegar/water). All tried out and all give warm water. I tried the ceramic disc valve (flow adjustment) in the off (closed) position and in the on (open) position, not really thinking that had anything to do with it, but tried it anyway. Still get tepid/hot water. All this involved taking out/replacing the cartridge multiple times to try different variations. I run the hot water tank down as far as possible before watering the garden but it's difficult having to fit that around a visiting daughter with children needing baths/ showers. Is there something simple that I am missing .... if so, can anyone point me to it, pretty please ???
