Hi,
I have a Bristan Pisa shower with a pump on it. Sometimes when I turn it on the water doesn't get hot so after a while I turn if off again and on the second or third time it does. When it doesn't come on warm sometimes the pump gives a little squeal but nothing changes. When the shower does start up warm I think the pump sounds quieter. Sometimes I have no problems at all.
What I am wondering is if I should be looking at the pump or the thermostatic cartridge? The temperature control knob has a bit of play on it by which I mean that it doesn't move the valve when you first start moving the knob. It also moves by itself sometimes a short way from the set position.
I have taken out the cartridge and it seems ok but I am not really sure what I should be looking for.
New cartridges seem to be expensive so I don't want to replace it unnecessarily!
Does anyone have any ideas as to what could cause this intermittent hot problem ?
Thanks
