[quote="sailorgeorge"]I had the same problem recently and I purchased a ball valve repair kit which includes new nozzle,wahers and split pin.Turn off the cold water main to prevent the header tank refilling and use a suitable scoop remove enough water from the header to take the waterline slightly below the original level (the tank is probably marked by a colour difference over time.Remove the split pin and remove the ball cock and arm.Udo the valve bodey and remove the piston with a screw driver into the ball valve arm slot.Then unscrew the end of the piston and replace the waher.Remove the nozzle from the body and replace with new.Lastly replace the larger o washer on the valve body.reassemble the whole thing and turn on the water main.Check the ball cock closes properly.[/quote]
I assume that you are referring to a header tank in the loft. I do not have one. it is a enclosed system. I dont really know how it works, I assume that it heats up the water as required???
