Why Is My Bathroom Sink Leaking Underneath?

A leaky bathroom sink can be a major annoyance, not to mention a waste of water. If you're dealing with this problem, don't despair. In most cases, it's a relatively easy fix that you can do yourself. Here are a few of the most common causes of bathroom sink leaks, along with instructions on how to fix them.

Loose or damaged supply lines

The supply lines are the flexible hoses that connect your sink to the water supply. Over time, these hoses can become loose or damaged, which can lead to leaks. To fix this problem, simply tighten the nuts on the supply lines. If the hoses are damaged, you'll need to replace them.

Faulty faucet cartridge

The faucet cartridge is a small, cylindrical device that controls the flow of water through the faucet. If the cartridge is faulty, it can cause leaks. To fix this problem, you'll need to replace the cartridge. Here's a step-by-step guide on how to do it:

1. Turn off the water supply to the sink.
2. Remove the aerator from the faucet.
3. Use a wrench to loosen the nut that holds the cartridge in place.
4. Pull the cartridge out of the faucet.
5. Insert the new cartridge into the faucet.
6. Tighten the nut that holds the cartridge in place.
7. Turn on the water supply to the sink.

Damaged drain pipe

The drain pipe is the pipe that carries water from the sink to the drain. If the drain pipe is damaged, it can cause leaks. To fix this problem, you'll need to replace the drain pipe. Here's a step-by-step guide on how to do it:

1. Turn off the water supply to the sink.
2. Disconnect the drain pipe from the sink.
3. Cut the damaged section of the drain pipe out.
4. Install a new section of drain pipe.
5. Reconnect the drain pipe to the sink.
6. Turn on the water supply to the sink.

Clogged drain

A clogged drain can also cause a bathroom sink to leak. To fix this problem, you'll need to clear the clog. Here are a few ways to do it:

• Pour a cup of baking soda down the drain, followed by a cup of vinegar. Let the mixture sit for 15 minutes, then flush the drain with hot water.
• Use a drain snake to clear the clog.
• Call a plumber.

If you're not comfortable fixing the leak yourself, you can always call a plumber. However, most bathroom sink leaks are relatively easy to fix, so it's worth trying to do it yourself first.
