Hi,
I've just changed the motorised valve on my CH system as it was leaking.
I think I might have an air lock, as the boiler will run for a few seconds but then shut down.
The radiators downstairs have all bled ok, but the upstairs rads seem to have very little pressure in them.
The pump is also noisy when it's running. (It wasn't before) Also the pump only starts when I turn on the CH, and not the hot water.
The boiler is a Potterton Netaheat HE50.
I'd really appreciate any advise.
Many Thanks
Geoff
