Hydro-Rain PVC Lock Fittings

Yes, these fittings can be installed underground. They’re a great choice for buried sprinkler repairs because they do not require glue, primer, or clamps. Plus, since there’s no glue involved, you can pressurize the line immediately after burial. They can also handle the natural shifting of the ground slightly better than rigid, glued joints, which can sometimes crack under extreme soil stress.

The best way to remove a PVC-Lock fitting is to use a PVC-Lock release tool. Slide the release tool over the pipe and press it into the fitting to disengage the internal locking teeth, then pull the pipe and fitting apart. Before removing the fitting, turn off the water and relieve pressure from the line. Avoid twisting or forcing the fitting off, as this can damage the pipe or fitting. Once removed, inspect the pipe end before reusing it.
