Step 8 · Test for Leaks

The moment of truth. Ensure the new hot and cold water valves on the outlet box are in the fully closed position. Go to the main water shutoff for the house and turn it on SLOWLY. Listen for the sound of rushing water, which should stop once the pipes are full. Return to the laundry room and use a flashlight to meticulously inspect every new joint and connection for any signs of moisture or dripping. Check the PEX tee fittings where you tapped into the main lines and the crimp connections on the back of the outlet box. If you see any leak, shut off the main water supply immediately and remake the faulty connection.
