Step 9 · Pressurize System and Check for Leaks

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Ensure the faucet you opened earlier is still open. Close any other faucets. Go to the main shut-off valve near the tank and open it SLOWLY. This allows the system to fill gradually, preventing a violent 'water hammer' effect. Once water is flowing steadily from the open faucet, go to the electrical panel and turn the breaker for the well pump back to the 'ON' position. The pump should start. Immediately check all new pipe connections and fittings for any drips or leaks. Use a flashlight to get a clear view. If you see a leak, turn the power off, drain the system, and tighten or re-do the leaky connection.
