If you have noticed some leaks under the sink, this means that you have to replace the sink strainer immediately. Minor leaks under the sink are due to poor seal where the strainer body and the sink come together. On the other hand, fixing the problem is an easy job to do. It can be done in less than an hour with the use of some plumbing tools and supplies which can be bought at a cheap price. The things that are needed are the new sink strainer with should be identical to the old one, pliers, a putty knife and a plumber’s putty. However, if you wish to reuse the old strainer, you can remove it, inspect and reinstall.

So, how to reinstall the sink strainer to solve leak problems? Here are some easy steps for you:

Step 1. Remove the tailpiece of the drain pipe

Most of the time, the strainer body is linked to a tailpiece that comes with a slip nut. The initial step is to loosen the slip nut by utilising an adjustable wrench. To remove it, try to turn it in a counterclockwise motion. Once the tailpieces are loose, unscrew it by hand, then remove it from the strainer.

Step 2. Unscrew the strainer locknut

Same with the tailpiece, you can remove the strainer by unscrewing it in a counterclockwise motion with the use of a wrench. The suitable wrench for this operation is a special wrench designed to fit the locknuts or it’s also possible to use a large pipe wrench. This operation can be a little tricky. Aside from the wrench, a screwdriver with the help of a hammer can also be used. Put the screwdriver on the lugs and tap it with a hammer. After removing the locknut, you can now pull the strainer out from the sink.

Step 3. Remove old putty and clean the strainer

You can use a putty knife in scraping old putty around the strainer. Then, clean it with the use of a scouring pad. Make sure that the pad is soaked with a paint thinner. If you’re planning to reuse the old strainer, make sure to clean it also. However, if you’re using a new one, wipe its underside with the use of a paper towel or a dry cloth.

Step 4. Apply plumber’s putty

Try to make a rope out of putty and place it on the sink’s opening. Then, insert the strainer in the opening and press it firmly. You will notice that some putty will be squeezed out around the opening. What you need to do is to remove the excess putty.

Step 5. Reinstall drain pipes

After all the steps, place everything back to its original position. Screw the lock nut until the strainer is tightly locked. However, make sure not to overtighten it. Then, put back the drain pipe tailpiece. If everything is put into place, test if the leak is repaired.
