Step 5 · Restore Water and Check for Leaks

Double-check that all your new connections are secure. Close all the faucets you opened earlier. Go back to the main water shut-off valve and turn it on slowly, counter-clockwise. You will hear the pipes filling with water. Once the valve is fully open, return to your work area with a flashlight and a dry rag. Carefully inspect the new tee fitting and all connections for any signs of dripping or moisture. Wipe the connections dry and watch them for a few minutes. If everything is dry, run the appliance (the washing machine) through a cycle to test the system under pressure and confirm that the loud banging noise has been eliminated.
