How to Seal a Bathroom Sink Drain

A leaking sink drain can be a frustrating and annoying problem. Not only can it waste water, but it can also lead to mold and mildew growth if not addressed promptly. Luckily, sealing a bathroom sink drain is a relatively simple task that can be completed in a few steps.

Materials Needed

To seal a bathroom sink drain, you will need the following materials:

Plumber's putty
Putty knife
Adjustable wrench
Rags or paper towels

Step-by-Step Instructions

Follow these steps to seal a bathroom sink drain:

Turn off the water supply. This is typically done by turning the valve located under the sink. If you cannot locate the valve, you may need to turn off the main water supply to your home.
Remove the drain stopper. This can usually be done by simply pulling it up. If the stopper is stuck, you may need to use an adjustable wrench to loosen it.
Clean the drain opening. Remove any debris or old plumber's putty from the drain opening using a putty knife. Wipe the opening with a rag or paper towel to remove any remaining moisture.
Apply a bead of plumber's putty around the drain opening. Use your fingers or a putty knife to smooth the putty into an even layer. The bead of putty should be about 1/4 inch thick and extend about 1 inch beyond the edge of the drain opening.
Reinstall the drain stopper. Press the stopper into the drain opening and tighten it using the adjustable wrench. Be sure to tighten the stopper until it is snug, but do not overtighten it.
Turn on the water supply. Check for leaks around the drain. If you notice any leaks, tighten the stopper further or apply more plumber's putty.

Tips

Here are a few tips to help you seal a bathroom sink drain:

If you are having trouble getting the drain stopper to seal properly, you may need to replace the washer. The washer is a small rubber gasket that fits between the stopper and the drain opening.
If the leak is coming from the base of the drain, you may need to replace the drain flange. The drain flange is the metal ring that is attached to the bottom of the sink.
If you are not comfortable working on your plumbing, it is always best to call a plumber for assistance.

Conclusion

Sealing a bathroom sink drain is a simple task that can be completed in a few steps. By following the instructions above, you can easily fix a leaky drain and prevent water damage to your bathroom.
