    Hubby and I have a leak in our sprinkler system. We tracked it to a collar or junction just before/after the main sprinkler box. So we need to replace that. Well it looks threaded and we've tried to turn it without much luck. Being so close to the elbow we are reluctant to cut it unless we have to.

    ETA_ I guess it's a compression coupling??

    The part that is leaking is imprinted with
    "Flo Burb, CA"
    1" I.P.S.

    Anyone have any thoughts on this? TIA

    It might be a sliding coupling that is leaking around an O-ring. Better to buy some PVC unions and rebuild the whole shebang.

    Why is it there? Could it be a check valve or pressure reducer?

    leak

    IT is a sliding "slip fix" repair coupling. The only way to repair that one is to cut it out and install a new one.

    Thanks folks - I appreciate the help so much!!
    It was a repair coupling -which was my guess last night -this part of the lawn is very root-y. The whole thing had a crack in it, so the leak was along the entire length of it -could be from a freeze I guess.

    The dudes at home depot swore it was a check valve, so I bought a new check valve and all the accessories to make it work, but we got home and cut it out and it is just a plain ole conduit.

    So we went back to home depot to get the repair coupling (which my gut was telling me to pick up the first time) and brought that home only to realize that one of the pipes is actually 1 1/4" ARGH -we had a 1 1/2"-to-1" reducer but not the 1 1/4, so we are now on our third trip to home depot!!

    I hope once we get this connected we hope we don't have a gazillion other issues. The leak was severe enough that we couldn't get enough pressure to fire up the sprinkler heads and so we turned off the water to the sprinkler system in spring 2007, so I'm expecting that many of the heads will not work and we may have a few other problems -so you might see me around here a bunch!

    Thanks for helping me on this one!

    Okay now we have a problem - it's not a 1 1/4" or 1 1/2" so we can't find a fitting...eeek.

    You need to dig away more soil, and see what's what. You are not going to see any PVC sprinkler pipe that isn't sized to IPS standards. Pipe damaged by freezing water or by lightning is another story.

    That is a siding slip fit coupler used to rejoin pipes underground when a repair had been made. The are sized by the pipe that is being connected. It looks to me like the pipe is 3/4", but hard to judge from the photo. At any rate, the couplers come in all standard PVC pipe sizes. Hard to say for why this is leaking, but possible from freezing. This is such a basic part, even Smock Man should be able to ID it, but as we all know, often SM is just a clerk. If there is an irrigation supply company in your area, they can provide you with what you need.

    Okay - we have it all fixed! The piece we cut that was not a regular pipe size was a part of the extension coupling, so we cut that off, which meant digging more and having to replace a T. Which we did. e actually dug enough that we had enough give in the pipe that we were able to make the repair with a coupling and straight pipe. Once we got it all cut off to actual pipe, it was quick to build it back.
    We waited a few hours and rand the sprinklers - we have a few problems with some heads that need to be replaced, but we are fixed!!

    Thanks folks!
