Shut Off the Water

Before you start working on the leaking pipe, you must shut off the water supply. Look for the shut-off valve under the sink and turn it clockwise to stop the flow of water. If you cannot find the shut-off valve, turn off the main water supply to your home.

Place a Bucket or Basin Under the Sink

Once you have shut off the water supply, place a bucket or basin under the sink to catch any water that may still be in the pipes.

Inspect the Pipes

Inspect the pipes under the sink to determine the location of the leak. Look for any visible damage, such as cracks or holes, in the pipes. If you cannot see any damage, run your hand along the pipes to feel for any moisture.

Tighten Loose Connections

If the leak is coming from a loose connection, use an adjustable wrench to tighten the nut that is causing the leak. Be careful not to overtighten the nut, as this can cause damage to the pipe.

Replace Damaged or Corroded Pipes

If the pipe is damaged or corroded, you will need to replace it. Use a pipe cutter or hacksaw to cut out the damaged section of the pipe. Be sure to measure the length of the pipe you need to replace and cut the replacement pipe to the same length. Use a pipe wrench to tighten the fittings on both ends of the new pipe.

Clear Clogs or Blockages

If the leak is caused by a clog or blockage, you will need to clear the obstruction. Use a plunger or a snake to clear any clogs in the drain. If the blockage is in the pipe, you may need to remove the pipe and clean it out.

Reconnect the Pipes

Once you have fixed the problem, it is time to reconnect the pipes. Use plumber’s tape to wrap the threads on the pipe fittings to create a tight seal. Use a pipe wrench to tighten the fittings securely.

Turn on the Water

After you have reconnected the pipes, turn on the water supply to test for leaks. Check for any leaks around the pipes and fittings. If you still have a leak, turn off the water supply and check the connections again.
