hello i have an indirect system and after draining the system down to install new basin & bath taps(no iso valves!) i had an air lock on the cold basin & bath feed. the kitchen cold feed was fine though.
i fixed the cold air lock using the garden hose & round tap connector to the basin, to push the air throught the vent pipe in the loft. job done.
but still no hot water, the rads are piping hot but the hot taps are running cold. i take it theres an airlock in the dhw feeds somewhere?
the boiler is situated right next to the cylinder upstairs.
how do i tackle an air lock on domestic hot water? same method as cold?
any help would be much appreciated.
