Hi,
The hot water pipe from my hot water cylinder appears to be airlocked. When I turn on a hot tap, I get a reasonable (but not massive) flow for about half a second, then just a trickle. There is a header tank in the loft, with feed going to the hot tank which is on the ground floor of the house. The pipework is a bit of a mess, and it seems that somewhere it's airlocked between the tank and the rest of the system. I found a bill the previous owners had paid for the freeing of an airlock. Written on the bill was a warning that the problem would recurr unless the problem was sorted. I can't get a plumber before Christmas. Can someone please tell me how to free an airlock so that I can have some hot water until I get the pipework sorted? Do I have to drain the whole system? If so how, given that it's airlocked...
Cheers,
Robert
