Hi, I have a 4 year old house and decided to tile the bathroom floor. I called a plumber out and when he came he had a look at my basin. He told me it had been fit illegally because it didnt have any isolating valves on the pipes to the taps. I phoned Wimpey up who built the house, they said it was good practice to fit isolating valves to the taps, but they didnt have to. Who is telling the truth.....
Regards Paul
