The kitchen sink drain has several components, each interlocking with another. The assembly consists of a strainer body, rubber gasket, metal washer and a large locknut or retainer. The strainer is mounted to the body by a straight tailpiece with a threaded coupling. Removing and replacing a gasket from the strainer is fairly simple with a monkey wrench. Should a garbage disposal be attached, however, the procedure is much more involved.

Things you need
- Monkey wrench
- Rubber gasket
Clear everything out from under the sink. You will see a rubber gasket and a metal washer under the drain as it connects to the drainpipe. There will be a large locknut holding the body of the drain in place.
Unscrew the locknut. Remove the friction ring and then remove the rubber gasket. Be careful not to inadvertently bend the drainpipe assembly or loosen the elbow joint.
Clean out the drain of any debris. Attach the new rubber gasket, then the friction ring and re-tighten the locknut.
Tips and warnings
- If your sink has a garbage disposal attached, seek advice at a hardware store or home improvement centre on how to remove/replace the sink drain gasket, or enlist the services of a plumber. You can also find information with the user's guide to the disposal that may include the steps needed in the process.
