Sink Drain Leaking At Nut

A leaking sink drain at the nut can be a frustrating problem, but it is also one that is relatively easy to fix. In most cases, the leak is caused by a worn-out washer or gasket. Replacing the washer or gasket is a simple task that can be completed in a few minutes with a few basic tools.

Tools You Will Need

Adjustable wrench
Phillips head screwdriver
Flat head screwdriver
New washer or gasket

Safety First

Before you begin, be sure to turn off the water supply to your sink. This will prevent water from leaking out while you are working.

Step-by-Step Instructions

1. Remove the drain stopper. The drain stopper is usually held in place by a screw. Use a Phillips head screwdriver to remove the screw and then pull the drain stopper out of the drain.

2. Loosen the nut. The nut is located at the base of the drain. Use an adjustable wrench to loosen the nut. Be careful not to overtighten the nut, as this can damage the drain.

3. Remove the old washer or gasket. The old washer or gasket is usually made of rubber or plastic. Use a flat head screwdriver to pry the old washer or gasket out of the drain.

4. Install the new washer or gasket. The new washer or gasket should be the same size and shape as the old one. Place the new washer or gasket into the drain and then tighten the nut.

5. Reinstall the drain stopper. Insert the drain stopper into the drain and then tighten the screw.

6. Turn on the water supply. Turn on the water supply to your sink and check for leaks. If there are no leaks, your repair is complete.

Tips

If you are having trouble finding the right size washer or gasket, you can take the old one to a hardware store and ask for help.
If the leak is coming from the base of the drain, you may need to replace the entire drain assembly.
If you are not comfortable making this repair yourself, you can call a plumber for help.
