'not sure how that s going to work mate . doubt blasting the main up the hot supply in the kitchen going to clear it an airlock in the cold supply ?'
Having re-read the post at the begining of this saga I realised this but I had the impression that the OP was not really receptive to advice and decided to leave the debate and not to respond further.
Although, I don't agree with jase158 with regards to bullying, I do think the whole post has got a little out of hand amongst ourselves.
Trouble is if we were all sitting in the pub having this discussion there'd be no misunderstanding because we could explain things clearly. Time and time again, things are read out of context or the meaning has been misconstrued and no-one wants to give in etc.
Funny thing is though the OP has given up and got a plumber in and hasn't posted any further.
Did the OP do any of the things suggested, probably not, he was probably looking for an easy soloution to the problem, all the suggestions required tools or some knowledge or ability. When the OP thought he sorted the problem in the morning or thought it sorted itself there was a bit of an attitude there. Two hours later though, was back looking for more advice...... I think this annoyed people.
On this happy note I'm off for my regular Sunday night surprise (or not so much of a surprise) between 9.45 and 10.00....
