Knowing that this could not be a drainage issue, we investigated the situation and found that there was a T fitting that had a crack in it. This T fitting connected the lateral line with the swing joint that led to the rough head nearest the native grass.
Once we dug down to the lateral line, we uncovered the swing joint and made cuts above and below the T fitting. It is interesting to point out how bad our gopher and ground squirrel problems are. In this photo below you can see that we dug into a ground squirrel burrow. This particular hole is where he was storing his native grass seed for the winter.
Back to our irrigation project. Here is a photo of where we made our cuts around the T fitting.
Once we had our two open ends, we measured each new piece of PVC and made the appropriate cuts and inserted a slip-fitting. Everything is held together with a very strong adhesive. The primer and glue holds together in a matter of seconds, so the process must be quick when fitting the pieces of PVC together.
The new T fitting was intact so we could now attach the swing joint.
Now that the head was screwed on and everything was re-wired, we could backfill the hole surrounding the lateral and swing joint.
The sod was then replaced and the lateral line was pressurized. The head worked great and there was now no leak in the T fitting. The soft area near the fairway will now begin the healing process.
