How Do You Seal Bathroom Sink Drain?
A leaky bathroom sink drain can be a nuisance, wasting water and potentially causing damage to your bathroom fixtures. Fortunately, sealing a bathroom sink drain is a relatively simple task that can be completed in a few minutes with the right tools and materials.
Materials You'll Need:
- Adjustable wrench or pliers
- Plumber's putty
- Washcloths or towels
- Caulk gun (optional)
- Silicone caulk (optional)
Step-by-Step Instructions:
- Turn off the water supply to the sink. This is usually done by closing the shut-off valves located under the sink.
- Remove the pop-up drain stopper. This can be done by unscrewing the small cap on top of the stopper and pulling it out.
- Clean the drain flange and pop-up stopper. Use a washcloth or towel to wipe away any debris or old sealant from the drain flange and the pop-up stopper.
- Apply plumber's putty to the drain flange. Roll a small piece of plumber's putty into a rope and place it around the base of the drain flange. Press the putty firmly into place to create a watertight seal.
- Reinstall the pop-up stopper. Insert the stopper into the drain flange and tighten the cap to secure it.
- Turn on the water supply and check for leaks. Slowly turn on the water and observe the drain for any signs of leakage. If you notice any leaks, tighten the stopper or apply additional plumber's putty as needed.
- Apply caulk around the drain (optional). For added protection, you can apply a bead of silicone caulk around the base of the drain flange. Smooth out the caulk with your finger or a caulk tool to create a watertight seal.
Additional Tips:
- If the leak is coming from the base of the sink, you may need to replace the drain gasket or washer.
- If you are not comfortable working on plumbing, it is best to call a licensed plumber for assistance.
- Regularly inspect your bathroom sink drain for leaks and address any issues promptly to prevent further damage.
