Thread: Water Line/Electrical/Gas in Same Channel

  1. #1

    Default Water Line/Electrical/Gas in Same Channel

    Hey guys,

    I've been faced with this decision a few times of putting a water line and an electrical box in the same stud channel. I've always managed to move one or the other to keep them seperated out of common sense. Same with Gas.

    So what is the code with multiple services in the same stud channel? Is it allowed by code?

    Water/Electrical

    Gas/Electrical

    Water/Gas

    Thanks

    The NEC is silent on the issue, so as far as it is concerned, it all can go into the same trench.

    You may have other (local) codes that may dictate otherwise. Call you local building department for a definite answer.
    Just my 2 worth.

    .

    If by "trench" you are literally talking about underground, I think that was not the question. He was talking about in the walls in the house, in the same 14" stud space.

    Default pipes

    As long as the electrical is 1" away from the plumbing lines it is okay. Which is why the plumbing is supposed to be installed before the electrical because they don't always install their wires so they can give that separation.

    What about gas and electric?

    I'm really surprised there is no code on this? I've always gone through great pains to keep them seperated like I did last night while installing a water line for a refridgerator with a recessed box in the wall.

    Thanks

    Would help if I read. All the words, too.

    But, I don't see any reason they cannot be in the same stud cavity, unless there is a local code against it.

    Why keep them separated? Water & electricity come together in you dishwasher, disposal, washing machine, well pump, etc.

    Gas & electricity come together in your direct-vent water heater, gas stove, dryer, range, etc.

    Gas & water come together in a direct-vent water heater.

    Makes sense. I guess I've done it for servicability. Though your right doesn't seem to be a reason for the madness.

    Thanks
