Had to fit a couple of isolation valves today on a hand basin. It had seperate hot and cold taps and a seperate central mixer spout. Underneath were the usual tap tails with tap connectors. Both tap tails connected to the central spout. Both tails also had another thread teed off which connected the hot and the cold taps together via a plastic tube which was about a metre long and was tucked in nicely behind the pedestal. Am I insane or was this just some DIY bodge? Anyone ever seen this?
