Thread: patching 3/8" hole in 2" PVC pipe

    patching 3/8" hole in 2" PVC pipe

    By mistake to placed the water temperature sensor in the wrong pipe in my pool system. No I need to patch the 3/8" hole in the pressure return pipe. Anyone have any idea beside cutting and putting on a coupling? I was hoping of getting some thing I can use with a pipe clamp.

    How about cutting a coupling in half, gluing, then clamping.

    How about installing a flowmeter in the hole?

    Otherwise I'd cut it and install a coupler or a Tee with a hose bib on it. That makes it easy to drain or to hook up an aerator sometime in the future.

    I'd just thread it and put a threaded plug in it. In fact that's what I did!

    That's one of the options I envisioned doing.

    Can you elaborate what tools I'll need and what plug? It's a 3/8" hole.

    flowmeter. That's also a great idea. Does it fit a 3/8" hole or do I also need another hole.

    in threading all you need is a tap and die set for a 3/8" or larger hole and find a plug with the same thread. Same with the flowmeter find out what thread it has and then tap for that thread. When you plug it, use some plumber's tape prior to plugging.

    The flowmeters I've looked at either need a 5/8" hole or a 3/4" hole to mount through. So you'd have to drill the 3/8" hole out.

    You can use a PVC saddle tee, or the first suggestion of taking a coupler and cutting it in half and using it as a patch over the hole.

    The tee outlet of the saddle tee can be centered over the hole, the saddle is then glued and clamped to the surrounding PVC pipe. Then just put a PVC plug in the tee outlet and you'll be all set.
