    Re: Tankless water heater installation with propress

    i don't believe the zinc fire theory. remember that the zinc/ galvanizing is just the surface and not the makeup of the pipe. why do you think that gal nipples are rusty at the threads when they sit around in a bunny box

    it's because the gal coating was cut off in the threading process.

    gal pipe is not allowed for gas in some jurisdictions because they feel the gal. flakes in the presence of gas.

    if they had to worry about a fire causing damage to the coating, then they must not worry too much about plastic piping, no hub bands, cast iron pipe, soldered joints.....
