You might notice some leaks found right below your sink. These leaks are due to a poor seal the strainer body and the sink come together. However, fixing a leaky sink strainer is not a hard thing to do. You can fix this in a matter of an hour with some plumbing tools necessary for the repair. You won’t also need to worry about the cost that you will be paying as you can do this on your own. Here are the steps in fixing a leaky sink strainer.
1. Remove the drain pipe’s tailpiece
The body of the strainer is connected to a tailpiece that has a slip nut. You can remove the tailpiece by simply loosening the slip nut through the use of an adjustable wrench. Turn the nut in a counter clockwise direction so you can loosen it. Once the nut already loosens up, unscrew it by the use of your hand. Then, you can finally remove the tailpiece of the drain pipe from the strainer.
2. Unscrew the strainer locknut
Through the use of a wrench, unscrew the strainer locknut. Turn it in a counter clockwise direction. There are various kinds of wrenches that you can purchase in the market. You can either choose between a special wrench that is designed to fit on the locknuts or opt for a large pipe wrench. There are some cases where this could be a little tricky. A screwdriver together with the help of a hammer can also do the job in unscrewing. Just put the screwdriver on the lugs then hit it with a hammer. Once the lock nut has been removed, you can now pull the strainer away from the sink.
3. Scrape off the existing putty and clean the opening of the strainer
There is some old putty that hardened around the opening of the strainer. It is necessary for you to get rid of this old putty. You can remove these with the help of a putty knife. With a scouring pad that is soaked with paint thinner, clean the strainer opening thoroughly. If you are planning to use again the old strainer, you have to scrape off the old putty around it and you also need to clean it thoroughly as well. But, if you will be replacing the strainer, be sure to wipe the underside of the replacement strainer with a paper towel or a cloth.
4. Apply plumber’s putty
Make a rope of plumber’s putty then put it on the sink’s opening. Install the strainer at the opening then press it down tightly. Once you’re done inserting the strainer, you will be noticing some plumber’s putty that squeezes out around the opening of the strainer. With this, you have to remove the excess plumber’s putty.
5. Reinstall drain pipes
Lastly, you need to put everything back to its original position. Reinstall each component one by one in an opposite order of how these were removed. Screw the locknut until the sink strainer is firmly locked in the sink. Make sure not to over tighten it. Afterwards, reinstall the drain pipe tailpiece through the use of a wrench. Once everything is in its place already, it’s time to check for any leaks. Test some leaks by simply turning the water on.
