A few days ago our power shower stopped working, probably due to the anti-scalding cut-out. I traced the problem to the 3 port valve (Danfoss 28mm) which does not shut off hot water to the hot water tank when rads are on only. So hot water is heated when rads are on! Also noticed that cold water feed to shower pump is getting hot when shower is off, so it seems the pump is mixing hot and cold feeds. I suspect the very hot water feed has damaged a seal within the pump (Jetforce 75). I have managed to shutdown hot feed to cylinder and to header tank by manual valves, so water is kept at safe temperature & header tank not heated up.
Any idea if pump can be repaired?
Thanks.
