Step 7 · Test for Leaks and Final Checks

This is the most critical step. Ensure the faucet handles are in the 'off' position. Go to the main water shut-off valve and turn it back on VERY SLOWLY to allow the pipes to fill gradually and prevent water hammer. Return to the access panel with a bright flashlight and dry paper towels. Meticulously inspect every connection you made: where the hot and cold lines meet the valves, and where the transfer hose connects to the valves and spout. Dab each connection with a paper towel to check for even the smallest drips. If all connections are dry, reach over the tub and turn the hot and cold handles on, letting the water run for a minute. Re-check all connections for leaks while the water is running.
