Hi, im looking at moving a rad about 3m from an internal wall to the external wall. The problem i will have is removing all the required floorboards to extend/re-route pipework. I was looking at trying the PB barrier pipe with the pushfit fittings mainly for ease but i have never used this before. Has anyone used it on their installations? Is it suitable, is it good enough to do the job and is it more prone to leak?
