Locating the Leak
The first step in fixing a leaking kitchen sink drain is to locate the source of the leak. The most common causes of a leaking kitchen sink drain are a damaged basket strainer, a cracked drain pipe, or a faulty P-trap.
Use a putty knife to scrape away any old plumbers putty around the drain. Once the putty is removed, inspect the drain for any visible signs of damage.
Replacing the Basket Strainer
If the basket strainer is damaged or worn out, it will need to be replaced. Use slip-joint pliers to loosen the locknut on the bottom of the sink.
Once the locknut is removed, you can pull out the old basket strainer. Clean the sink opening and apply a new layer of plumbers putty around the opening. Insert the new basket strainer and tighten the locknut.
Replacing the Drain Pipe
If the drain pipe is cracked or damaged, it will need to be replaced. Use an adjustable wrench to loosen the slip nuts on either end of the drain pipe. Once the slip nuts are removed, you can pull out the old drain pipe. Insert the new drain pipe and tighten the slip nuts.

Replacing the P-Trap
If the P-trap is the cause of the leak, it will need to be replaced. The P-trap is the curved pipe that connects the drain pipe to the main drain line. Loosen the slip nuts on either end of the P-trap using slip-joint pliers or an adjustable wrench.
Once the slip nuts are removed, you can pull out the old P-trap. Insert the new P-trap and tighten the slip nuts.
Reinstalling the Drain Pipe
Once you have replaced the damaged component, you can start reassembling the drain pipe. Apply plumbers tape to the threads of each slip nut to create a watertight seal. Insert the slip nuts back onto the drain pipe and tighten them using slip-joint pliers or an adjustable wrench.

Testing the Drain
Before you turn the water supply back on, it’s important to test the drain for any leaks. Place a bucket underneath the drain and turn on the water supply.
Let the water run for a few minutes and check for any leaks around the drain. If you don’t see any leaks, you can turn off the water supply and remove the bucket.
Tips for Preventing Future Leaks
To prevent future leaks, there are a few things you can do. First, make sure to clean your sink regularly to prevent buildup of food particles and other debris.
This can cause the drain to clog and lead to leaks. Second, avoid using chemical drain cleaners as they can damage the pipes and cause leaks. Finally, make sure to tighten the slip nuts on the drain pipe and P-trap regularly to prevent them from loosening over time.
