PEX Supply Line Repair: Push-to-Connect, Crimp Ring, and Compression Fittings
This hot side PEX supply line under a Pigeon Forge kitchen sink was joined with three different fitting types: a push-to-connect fitting at the copper stub-out, a crimp ring at the elbow, and a compression fitting at the angle stop valve. Only the crimp ring was a connection we'd have chosen ourselves.
