Step 9 · Test the Connection for Leaks

With the connection fully assembled and tightened, the final step is to test your work. If you turned off the main water supply, turn it back on now. Go to a fixture upstream from your repair (like a sink or toilet on the same floor or a floor above) and run a significant amount of water through the drain. While the water is running, carefully inspect the new connection at the coupling. Look closely at the top, sides, and especially the bottom for any signs of dripping or seepage. Wiping the joint with a dry paper towel is an excellent way to detect even the smallest leaks. If it remains dry, the job is complete.
