    Do I use teflon tape on cpvc connectors
    I screwed metal shut-offs on to cpvc male threads. They all leak. Did I overtighten? Should I use teflon tape?

    Use 3 turns on 1/2 inch pipe and 4 turns on 3/4 inch.

    Be sure to shut main before working on the valves.

    Check thread to see if u cross threaded when u put on valve.

    Agree, all threaded connections including NG and propane should use tape of paste. Water and gas do not use the same tape or paste.
