I am slowly replacing my pin-holed leaking galvanized plumbing, piece be piece with PEX and Sharkbite connectors. The old galvanized is secured, in many places by both clamps and u-nails. What is the best practice with PEX?

Best Answer
Yes. There are special plastic clamps that can be used with PEX so that the pipe does not wear. You should secure it about every 32 to 48 inches, and anywhere to prevent the expansion/contraction of the pipe to cause wear. It is not necessary to clamp where the pipe runs through holes in wooden joists/studs.
