There is nothing that makes a day worse than a leaking bathroom sink. The constant drip-drip, possible water damage, and subsequent waste would undoubtedly cause anxiety. However, you can keep your bathroom leak-free by being aware of the underlying problems. So, next time you ever wonder, “Why is my bathroom sink leaking underneath?” read this blog.
Why Is There a Leak in Your Bathroom Sink?
Unlike other plumbing leaks, a bathroom sink leak usually occurs only when the sink is in use, which is one of the reasons it is so dangerous. If water seeps into the foundation and flooring beneath a vanity, it may lie unnoticed for weeks or months, leading to damage, mildew, and other issues.
You can avoid this situation by keeping an eye out for leaks, but you also need to understand the cause of sink leaks and potential trouble spots. If you know where to check for problems, you can prevent problems before they arise and conduct efficient repairs.
Understanding the Bathroom Sink Leaks
Each sink is different, and what you might find in the kitchen is not always what you’ll find in the bathroom. It’s important to understand the potential causes of a bathroom sink leak before we get our hands dirty while fixing it.
There are three main areas where a bathroom sink might leak: the faucet, the drain pipe, and the sink basin:
1. Drain Pipe Leaks
The most common causes of drain pipe leaks are loose connections or pipe breaks. Your pipe may eventually split, or the joints between its various pieces may become loose, allowing water to seep out.
2. Faucet Leaks
The part of a sink where water comes out is called the faucet. Leaks from faucets usually result from worn-out parts. Time, use, and hard water can erode several components, including the cartridge, washers, valve seat, and O-rings, resulting in leaks.
3. Sink Basin Leaks
The most common cause of sink basin leaks is broken seals around the sink drain. Water may leak out of the drain assembly due to deterioration of the putty or sealant holding it in place over time.
How to Fix a Bathroom Sink Leak Underneath?
Bathroom sink leak is more dangerous than any other sink leak. The sink only leaks while it is in use, so there isn’t a constant flow that may result in a visible puddle. It’s possible that floor wood will absorb the water and hide the leaks. However, over time, the wood rots and the bathroom’s relative humidity increases dramatically.
Since a bathroom sink leak is a serious issue, it shouldn’t be fixed by some DIYs. You need to call a professional plumber.
