How to Fix Bathroom Sink Leaking at Base
A leaky bathroom sink can be a major inconvenience, and it can also lead to water damage if it's not fixed promptly. If you're dealing with a leaky bathroom sink, there are a few things you can do to fix it yourself. Here are the steps on how to fix a bathroom sink leaking at the base:
1. Identify the Source of the Leak
The first step is to identify the source of the leak. This can be done by visually inspecting the sink and looking for any cracks or holes. If you can't find any visible damage, you can try running the water and looking for any leaks around the base of the sink. Once you've found the source of the leak, you can start to fix it.
2. Tighten the Drain Nut
One of the most common causes of a leaky bathroom sink is a loose drain nut. The drain nut is located underneath the sink, and it holds the drainpipe in place. If the drain nut is loose, it can cause the drainpipe to leak. To tighten the drain nut, you'll need a wrench.
3. Replace the Washer
If tightening the drain nut doesn't fix the leak, you may need to replace the washer. The washer is a small rubber or plastic ring that sits between the drain nut and the drainpipe. Over time, the washer can wear out and start to leak. To replace the washer, you'll need to remove the drain nut and then remove the old washer. Place the new washer on the drainpipe and then re-install the drain nut.
4. Seal the Base of the Sink
If the leak is coming from the base of the sink, you may need to seal it. You can do this by applying a bead of silicone caulk around the base of the sink. Make sure to smooth out the caulk so that it creates a watertight seal. You may also need to re-caulk the seal around the drain.
5. Replace the Sink Drain
If the leak is coming from the sink drain, you may need to replace the drain. To do this, you'll need to remove the old drain and then install a new one. Make sure to use a plumber's putty or caulk to seal the new drain in place.
6. Call a Plumber
If you've tried all of the above steps and you're still unable to fix the leak, you may need to call a plumber. A plumber can diagnose the problem and fix the leak for you. They may also be able to tell you if you have any leaks in your pipes that may be causing the leak in your sink.
