NDS 118-10 Pro-Span 1-Inch Expansion Repair Coupling for Broken or Cracked Pipe, White

Love these repair sleeves! So far no negative comments with my original repair in the ground for over 3-years (and shallow might I add so zero-turn and my small 30 hp tractor routinely drives over). I now maintain a selection for the pipes I have in the ground of 3/4” and 1” sprinkler piping. Benefits: - reduced labor - since the sleeve allows for bridging the gap of a broke section, I do not have to open as much ground as I did with using a collar or installation of a union (which I have had leaks from due to running over the ground after repairs to pack it down - reliable - see note above as I was concerned about kinking, roots, etc causing the sleeve to leak around the sliding seals but solid as a rock so far - cost effective - I prefer this due to the above comments although the collar is always cheaper but I had to open 3-4 feet of hole on either side of the break and closely estimate the cutting length before pulling the pipe up in an arc to gain enough clearance to slide the pipe fitting(s) onto the repaired section. Hope that makes sense?

No instructions come with it. Installed as per website instructions. Leaked after allowing glue to dry. Contacted manufacturer and asked about the proper positioning of expansion piece. They say it should be at mid travel, no where is that discussed anywhere I looked. Who recommended using if downstream of solenoid valve incase of leak.

I reviewed their installation video from the manufacture that is on their YouTube channel. I was impressed of the quality of manufacture and the ease of installation. This unit is made in USA and works better than the cheap imports you get at local big box hardware stores that I had to replace too many times. Like them so well that I have extras ready to use if needed. I have already loaned some to a neighbor.

The telescoping tube does not need to fully extend but does need to engage the locking notches at the female connection end. It works anywhere in between, almost closed and/or fully extended. Also, the male end will fit into a solenoid valve or other fitting. Don't really need a coupling it that end works in another fitting. Saves having to flex existing pipes to dry fit & glue. I used it to install a new solenoid valve. Kept the hole smaller. They could make a very video. It does not make a clicking sound as you rotate the tube. Just the seals rubbing up against the inner tube. If you can flex the pipes to dry fit & glue don't need it. Save the money.

I had just finished bragging to my dad that I had never had a PVC weld leak. He turned the main back on--and I had a leak. The good news is, my record still holds. The leak wasn't coming from any of my PVC welds but from the slip joint in the middle of this thing. The concept is fantastic and I've used these before (maybe from a different manufacturer?) without incident. I don't know how to get the job done without one of these but be sure you use it in a place where you can cut it out and try again if the first one doesn't work. In my case, I glued this directly into a complex manifold and now I'll have to rebuild the entire unit because I can't cut this out.
