Mick, thanks for the quick reply just to confirm what i think you meant?
are you saying that there is probably two valves??
one is next to my tank ..........the other would be ??? (not so obvious) :cry:
thanks
hi,
i have a potterton flamingo 40 boiler,with a randall 4033 switch, my problems is that none of the timings are now working so to have hot water the heating comes on as well. the valve i have is a danfoss 2port HPA2 would this cause the problem?? i moved the arm to manual very slight...
