Bathroom Sink Pop Up Drain Leaking: Causes and Solutions

A leaky pop-up drain in your bathroom sink can be a frustrating and annoying problem. Not only can it waste water, but it can also lead to mold and mildew growth. Fortunately, fixing a leaky pop-up drain is usually a relatively simple and inexpensive task that most homeowners can do themselves.

Causes of a Leaking Pop-Up Drain

There are a few different things that can cause a pop-up drain to leak. The most common causes include:

Worn or damaged O-rings
A loose or damaged lift rod
A cracked or broken drain body

How to Fix a Leaking Pop-Up Drain

The first step in fixing a leaky pop-up drain is to identify the cause of the leak. Once you know what's causing the leak, you can follow these steps to fix it:

1. Replace the O-rings

The O-rings are small rubber gaskets that create a watertight seal around the drain body. Over time, the O-rings can become worn or damaged, which can cause the drain to leak. To replace the O-rings, simply remove the drain body from the sink and replace the old O-rings with new ones.

2. Tighten the lift rod

The lift rod is the metal rod that connects the pop-up drain to the sink stopper. If the lift rod is loose, it can cause the drain to leak. To tighten the lift rod, simply use a wrench to tighten the nut that secures the lift rod to the drain body.

3. Replace the drain body

If the drain body is cracked or broken, it will need to be replaced. To replace the drain body, simply remove the old drain body and install a new one. Be sure to apply a generous amount of plumber's putty to the rim of the new drain body before installing it.

4. Call a plumber

If you are unable to fix the leaky pop-up drain yourself, you can call a plumber. A plumber will be able to diagnose the problem and fix the leak quickly and efficiently.

Conclusion

Leaking pop-up drains can be a nuisance, but they are usually a relatively simple and inexpensive problem to fix. By following the steps outlined in this article, you can fix the leak and get your bathroom sink working properly again.
