Gas boiler downstairs with timer near. Upstairs is the Cylinder with a Pump and a motorised valve near. The pump sits on the bottom leg of a T. The valve sits on the cross section of the T. At the moment when I have the hot water on all the radiators seem to be getting hot? All ! not just the upstairs ones. The actuator on the valve seems to be moving OK when heating is switched on or off. Could it be the valve its self thats kn**kered? Can't see a check valve anywhere!
