    Default air lock in hot water system

    With your help I have fixed my thermal store central heating system. However I seem to have air lock in hot water. All taps except bathroom give hot water. Bathroom is a dribble. have tried fixing washing machine hose to cold and hot fill to blast airlock. No success. Any other options?

    Well your hot water should be main pressure through thermol store so should not have air lock,is it just one tap that is not working,if so could be tap or a bit of rubbish stuck in both taps
    However as you was working on system last week,check no valve is closed to bathroom or not opened correctly

    imho

    Hello again.
    yes it is only bathroom hot tap. All other work ok. Bathroom tap becomes an old man's dribble accompanied by knocking noise. have tried the mains cold to hot system using the washing machine pipe but no success.

    Well if tap knocking and dribble, probably tap head faulty,do not know what taps you have maybe ` 'adapt a tap' or 'tap revivers' or 'standard tap' heads will fit or isolate water supply and remove head and see if jumper can be fixed

    Washer is probably stuck inside the tap.
