Me and my husband are in the middle of renovating our home. Its a small mobile home. We are now to the point of the renovation for plumbing to be roughed in. I originally wanted to go back with CPVC, but my husband wants to use PEX. We have PB pipe now and because of that pipe, we have had to do a total gut job on the whole house due to water damage from leaking pipes. So far we have removed all of the PB pipe, and mapped out the new plumbing diagram, but which is safest to use in terms of water leakage? Does this new PEX tubing leak around the fittings like PB? It seems like it is the same stuff.
