    Gas pipe from house to garage?
    I know this pipe requires an outside shutoff valve at the destination (garage). Does it also require a valve at the source (house)?

    Hi Camel,

    Your gas line will have a shut off at the meter and another at the connection to the appliance it will serve.
    Your local code may also call for a drip loop to be installed. A drip loop consists of a downturned tee cut in just after the meter with a 6" nipple terminating in a cap or a petcock. The gas line should be installed with a slight slope, (1/8th inch to the foot) back to the meter.
    The reason for a drip loop is to trap and contain any moisture that accumulates in the line before it gets to the pilot light and extinguishes it.

    Good luck, Tom

    Do not use a junky gate valve on a gas line. Use a gas cock or better yet, a modern ball valve. Also make sure the valve says WOG on it, water, oil, gas to meet code. Ball valves leak less, both internally and externally, and a quick 90 degree turn shuts it off or turn it on.

    Otherwise, do just as Tom said.
