Step 7 · Testing for Leaks and Performance

After allowing the PVC cement to cure according to the manufacturer's instructions (typically 15-30 minutes for handling, longer for full pressure), it's time to test your work. Reconnect the P-trap to the sink drain. Turn on the faucet and fill the sink completely with water. Then, release the stopper and let it drain all at once. Watch all the new joints carefully for any signs of leaks. Listen for the sound of the AAV opening; you may hear a faint hiss as it draws in air. The water should drain quickly and smoothly without any gurgling sounds.
