Installing PEX water service connections in three easy steps
With crosslinked polyethylene, or PEX, now being the most installed plumbing-piping product in new-residential construction — more than copper and CPVC combined — an increasing number of product solutions are coming to market to accommodate a PEX plumbing system.
Take, for example, new fittings and valves that are now available for connecting PEX pipe to water meters using an ASTM F1960 cold-expansion connection. Before these direct connections were available, plumbing installers had to add an additional adapter fitting in between the meter connection and the PEX fitting. Now, they can directly connect from the meter to the PEX pipe with only a single part.
