Hello all, i wonder if anyone point me in the right direction in locating the 3 way port valve on my central heating system. The reason i am asking is because i am unable to get hot water without turning on the central heating, so you can imagine i'm sweating buckets. I currently live in a bellway house that was built in 1978 with the same boiler sysyem installed (Thorn Olympic). I have looked around the hot storage tank in the airing cupboard, in the loft and next to the water pump in the kitchen. Any idea where it could be?
