I've had two underfloor leaks (copper piping under and through slab on grade concrete floor) and now plan to re-plumb most of my house with PEX. I'm very sure the leaks are the result of poorly protected copper in contact with concrete which has pitted and finally caused pin holes in the copper. My plan is to abandon all under floor copper and use PEX fed through the attic. Some of the cold and most of the hot water is above the floor, so I want to connect PEX to copper in those instances. I'm not a plumber and I've never used PEX so I'm at ground zero. Any guidance would be appreciated !
