Thanks for your answers. I paid him cash (he's a local) as he came out that morning and had the replacement plastic pipe on his van and it was almost certainly not recorded. Actually it was him that fractured the pipe in question when he was called to replace a ballcock in the tank . The fracture of the pipe was obviously only a crack at first and held out for a few months. He is unaware of my deduction but expressed astonishment when he saw what caused the flood of water, "Never seen anything like that before!" This is only one of several bodge-ups. Why use him? Well he lives just 2 miles away, schoolfriend of my brother and I would have had to spend time on the internet to locate another 'mid flood' with call out costs, VAT etc. I always say never again but then an emergency arises.
