1. Tightening the Drain: To establish a suitable seal for your vanity sink drain, follow these steps:

1. Hand-Tightening: Start by hand-tightening the drain into the sink. Use your fingers to rotate the drain clockwise until it is snugly fitted. Avoid using excessive force during this step.
2. Checking for Leaks: After hand-tightening, carefully inspect the drain for any signs of leakage. Turn on the water and let it run for a few minutes. If you notice any leaks, proceed to the next step.
3. Slight Additional Turn: If there are leaks, you can cautiously use pliers or a wrench to give the drain a slight additional turn. Remember to exercise caution and avoid exerting excessive force. The objective is to achieve a secure seal without jeopardizing the sink or drain's integrity.
   

2. Troubleshooting: In case you encounter issues with the seal despite following the above steps, try the following troubleshooting tips:

1. Inspecting the Drain Components: Carefully examine the drain components, including the rubber gasket, washer, and any other associated parts. Ensure they are in good condition and free from damage or wear.
2. Applying Plumber's Tape: Consider applying plumber's tape, also known as Teflon tape, to the threads of the drain before tightening it. This tape helps create an additional barrier against leaks.
3. Seeking Professional Assistance: If you have followed the above steps and are still experiencing issues with the seal, it is advisable to seek professional assistance. You can contact our dedicated support team at 1.866.839.2888 or open a Support Ticket for further guidance and expert advice.
