How to Stop a Leak Under Bathroom Sink

A leak under the bathroom sink can be a frustrating and potentially costly problem. Not only can it waste water and increase your water bill, but it can also lead to damage to your bathroom floor and cabinetry. Fortunately, most sink leaks are relatively easy to fix with a few simple tools and materials.

Identifying the Source of the Leak

The first step in stopping a leak is to identify the source. There are a few common places where leaks can occur, including:

The faucet
The drain
The supply lines
The P-trap

To identify the source of the leak, inspect each of these areas carefully. Look for any signs of water damage, such as wet spots, corrosion, or mold. You may also be able to hear the sound of dripping water if the leak is coming from the faucet or drain.

Fixing the Leak

Once you have identified the source of the leak, you can begin to fix it. Here are some tips for fixing common sink leaks:

Faucet leak: If the leak is coming from the faucet, you may need to replace the washer or O-ring. These are small, rubber gaskets that create a seal between the faucet handle and the body of the faucet. You can find replacement washers and O-rings at most hardware stores.
Drain leak: If the leak is coming from the drain, you may need to tighten the drain nut. This is the large nut that holds the drain in place. You can tighten the drain nut using a pair of pliers.
Supply line leak: If the leak is coming from one of the supply lines, you may need to replace the washer or O-ring. You can also try tightening the connection between the supply line and the faucet or drain.
P-trap leak: If the leak is coming from the P-trap, you may need to replace the P-trap. The P-trap is the U-shaped pipe that connects the drain to the sink. You can find replacement P-traps at most hardware stores.
