NDS 118-07 Pro-Span PVC Expansion Repair Coupling, For Broken or Cracked In-Ground PVC Pipes, 3/4-Inch IPS Slip X Spigot, White

I used this to make it easy to tee off of a sprinkler line. No leaks and easy to install.

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.

An ingenious solution that makes connecting and repairing PVC sprinkler lines a snap! Well-made and surprisingly easy to use compared to traditional PVC fittings, these expansion-repair couplings take a fraction of the time—plus less effort digging and trenching—to install versus a conventional repair. As an avid home landscaper, I strongly recommend keeping one or two of these on hand for quick, easy installations and emergency repairs.

Works just as described very easy
