I have had a stray cat live in my garage for the last year - two weeks ago to my amazement she had four kittens!!!!! Unfortunately two of the kittens died but the two which are left have just opened...
After draining down to make a plumbing repair and refilling the system I now have an air lock in the hot water system. Please... Please ....can anyone help. I have tried holding a rag over a mixer tap...
