Step 5 · Inspection and Testing
DO NOT backfill the hole or cover your work yet. Follow the manufacturer's instructions for the PVC cement cure time before allowing significant water flow. Contact your local plumbing inspector to schedule the required inspection as per your permit. The inspector will verify that the correct type of valve was used, that it is installed in the correct direction and location, and that the connections are sound. After you receive official approval from the inspector, you can perform a leak test. Have someone flush an upstairs toilet or run a sink for a minute while you closely observe the new connections with a flashlight to ensure there are absolutely no drips or leaks.
