    Default What pressure for air testing copper?

    Hello,

    I'd like to pressure test my vertical spa installation (lots of fittings). It has held 40 PSI for 4 hours.

    What is the recommended air pressure and set time for air testing copper? The valves are installed. I did not want to risk over pressurizing the valves.

    Thanks,
    Steve

    Default test

    The valves are rated for 150 psi working pressure and no common compressor is allowed to exceed about 125 psi, so you couldn't damage the valves.

    Thanks a ton! The max pressure was exactly what I was just scratching my head about.
