hi tony
the auto air vent was changed it but noticed slight bit of water at the valve when looked before is this normal? not the pump stat though
cheers dean
it sounds like the gurgling is at the top of the boiler when hot water running is it possible air trapped in the gas to water exchanger?you can have a shower or run a sink of hot water but when you turn off boiler goes off as the boiler gets really hot to touch so the over heat stat cuts it off...
