Here’s a list of what you’ll need:

Adjustable wrench
Plumber’s tape

steps to follow to fix leaking pipe underneath sink

First, identify the source of the leak. Common culprits include the P-trap, supply lines, drain pipes, and faucet connections. Look for visible signs of water, like wet spots or pooling under the sink. Use a flashlight if necessary to inspect hard-to-see areas. Once you're certain where the leak originates, you're ready for the next steps.

Next, prepare the area. Clear out any items stored under the sink to give yourself ample workspace. Place a bucket or an old rag underneath the leak to catch any drips. This will help keep your workspace dry and prevent further damage to the cabinet or floor.

With your tools and workspace ready, it's time to move on to the actual repairs. The method will vary depending on the leak's source:

Leaky P-Trap: Use an adjustable wrench or slip-joint pliers to gently tighten the connections. If the leak persists, you may need to replace the washers or the entire P-trap.
Supply Lines: Check for any loose connections and tighten them. If the line itself is damaged, replacing it is the best option.
Drain Pipes: Look for cracks or splits. Depending on the damage, you might need to use plumber’s putty or Teflon tape as a temporary fix. For a more permanent solution, replace the damaged section of the pipe.
Faucet Connections: Turn off the water supply and carefully remove the faucet to inspect the seals and gaskets. Replace any worn parts and reassemble the faucet, ensuring everything is snug and leak-free.

Finally, once all repairs are complete, turn the water supply back on and check for leaks. If you've done everything correctly, your sink should now be leak-free. Congratulations on a job well done!
