Leaking Sink? Common Causes & How to Fix It

Picture this: You’ve just finished dinner (maybe you cooked, maybe you didn’t) and head to the kitchen to do the dishes. Suddenly, you notice water pooling around your sink. You’ve got a leak.

The Problem with Leaks

Leaking sinks are more than just a nuisance. Left unchecked, they can cause serious damage to your home’s structure and lead to mold growth, which poses health risks like asthma and sinus infections. Plus, the excess water could skyrocket your utility bills.

When your sink starts leaking, you need a quick fix to protect your home and family.

Common Causes of a Leaking Sink

1. Faucet Leaks

Faucet leaks are easy to spot—usually, water pools at the base. Sometimes, the leak happens underneath, making it less noticeable. The culprit is often a worn-out gasket or washer. Replacing these small parts can stop the leak.

2. Clogged P-Trap

The P-trap, that U-shaped pipe under your sink, can get clogged with debris over time. This causes water to back up and leak into your cabinet. To fix it, remove the P-trap, clean it out, and reattach it.

3. Corroded Valve Seat

The valve seat connects the spout to the faucet. Over time, water buildup can cause corrosion, leading to leaks. Regular cleaning and maintenance can prevent this.

4. Water Supply Line Issues

Your sink’s water supply lines can also be the source of a leak. Check the connections regularly, as these can wear out or become loose, especially if your sink has multiple connections for a sprayer.

How to Check for Leaks

Faucet Leaks

Check for water pooling around the sink and underneath in the cabinet. If you find a leak, replacing washers or gaskets is usually all it takes. If that doesn’t work, it might be time to replace the entire faucet.

Drain Seal Leaks

If your faucet isn’t the problem, the drain seal might be. A loose or broken drain seal will cause water to drip out of the sink when filled. To fix it, replace the old seal and apply new adhesive around the drain.
