We had a kitchen tap problem. No hot water. We don’t have a tame plumber, but coincidentally that same day we had received a tradesmen’s flyer so we went with one of the plumbers listed.
He turned up on time, he was a very nice man and he seemed to know what he was talking about. He assessed the problem, diagnosed elderly pipework, did some more tests, re-diagnosed elderly pipework plus a faulty tap and told us what we needed to replace it with – a new tap capable of handling low water pressure because of the pipework.
