Sprinkler PVC cracked near prevous repair coupling


We have a leak spraying out right next to an existing repair coupling (see pic). Presumably, we are going to have to completely cut out the old repair coupling to fix this. However, this is going to leave a much larger gap than can be bridged by a standard coupling.

Is there a special piece we need to bridge this larger gap?

Any advice you can lend that will help with this repair will be greatly appreciated!

If you have some flex in the pipe, two regular couplings and a piece of pipe will get you going. If there's no flex, look for slip-couplings. They are couplings without a stop inside. You put the couplings over the pipe then slide them over the joint.

Look for an expandable repair coupling. Make sure everything is clean and dry, use PVC primer, and let the glue cure for a while before you turn it back on.

I'm saying that is the original break that pulled itself out of the coupling because it was pressurized before glue set. Look at the blue rain/shine glue ring around that split
