    2" PVC repair coupling (the kind without the hub, and not the slide extend-a-thing): The two ends of the PVC pipes will almost touch, do I prime and glue both pipes, then slide the repair coupling down on the joint, with a twisting, jerking motion (sorry, that's an old Chris Farley line)?
    Thank you

    I've never actually used one, but yes. The tricky part is not letting it get stuck before you reach the final position. Mark where you want the end to be.

    And I think you want to prime the coupling before you slide it on the pipe, the only reason not to would be if it causes the coupling to get too sticky. But it would definitely make a better joint.

    Cheers, Wayne

    If you can lift both pipes high enough you can use a regular coupling. I don't trust using a slip coupling on PVC.

    Is that due to the difficulty getting it in the incorrect location, or the inability to apply glue to the coupling itself, and so the likelihood of not getting complete coverage?

    Cheers, Wayne

    I have worked miles and miles of high pressure 2" in golf course irrigation. I agree with above that I just don't trust those slip couplers. Not because they won't work, but because you don't always know exactly how everything will fit until you throw the glue. You have seconds. I agree with digging up more or using the telescopic repair. If you feel froggy, you can also go with an Oring union but will need to get the pipe lengths right.

    If you want this put to bed the right way, dig, bend, and use the right coupler. Regardless, use primer! Every leak I ever see is a lack of priming. I do it even for DWV.
