Why Your Bathroom Sink Drain Is Leaking And What You Can Do About It

A leaking bathroom sink drain can be a frustrating and inconvenient problem. It can lead to water damage, mold, and mildew, not to mention the annoyance of constantly having to mop up water. But don’t worry, there are several common causes of a leaking sink drain, and most of them are relatively easy to fix. In this blog post, we’ll explore the seven most common reasons why your bathroom sink drain might be leaking and provide step-by-step instructions on how to fix each one.

Seven Common Causes of a Leaking Bathroom Sink Drain

1. Loose Drain Stopper

The drain stopper is a common culprit when it comes to leaking sink drains. Over time, the stopper can become loose, allowing water to seep out around the edges. To fix this, simply remove the stopper and tighten it back into place.

2. Worn-Out Washer

The washer is a rubber gasket that creates a seal between the drain stopper and the drain. If the washer is worn out or damaged, it can allow water to leak out. To fix this, simply replace the washer with a new one.

3. Cracked or Broken Drain Pipe

The drain pipe is the pipe that carries water from the sink to the drain. If the pipe is cracked or broken, it can leak water. To fix this, you will need to replace the drain pipe.

4. Loose Drain Nut

The drain nut is the nut that holds the drain pipe in place. If the nut is loose, it can allow water to leak out. To fix this, simply tighten the nut.

5. Clogged Drain

A clogged drain can prevent water from draining properly, causing it to back up and leak out of the drain. To fix this, you will need to clean out the drain.

6. Faulty Faucet

In some cases, a leaking sink drain can be caused by a faulty faucet. If the faucet is not properly installed or if it is damaged, it can allow water to leak out of the drain. To fix this, you will need to replace the faucet.

7. Damaged Drain Assembly

The drain assembly is the entire assembly that connects the sink to the drain pipe. If the drain assembly is damaged, it can leak water. To fix this, you will need to replace the drain assembly.
