Hi all, My customer would like new kitchen taps. The hot is piped in copper. But the cold is piped in an old, blue plastic 15mm pipe with glued joints. A previous plumber has warned her the pipe is old, cheap and brittle, with a high chance of cracking and leaking. To change the tap, he'd need to ripe out the old plastic and re-run copper pipe. He knows the estate and has seen it before. It seems a little drastic, but if the pipe really is so nasty, then best err on the side of caution. Ideally, I'd cut into this pipe, and put an isolation valve and then a flexi up to the tap. But without knowing what type of pipe this is, what fittings could I use? Or best just replace the lot? (which is what I'm thinking to do). Advice would be much appreciated. Thanks everyone. Jennie.
