Why Is My Faucet Leaking?

A leaky faucet is one of those small problems that can quickly become a big headache, not to mention a drain on your water bill. But what’s causing it to drip?

Let’s break down the most common reasons your faucet might be leaking and what you can do about it.

What Are the Most Common Causes of a Leaky Faucet?

There are several reasons a faucet might start dripping.

1. Worn-Out Washers

This is the most common cause. Over time, the rubber or silicone washers inside your faucet can wear down due to friction. Once they lose their seal, water starts to leak.

2. Damaged Cartridge

If you have a cartridge-style faucet (commonly found in modern sinks), a worn or cracked cartridge can cause dripping. Replacing the cartridge usually fixes the issue.

3. Corroded Valve Seat

The valve seat connects the faucet to the spout. If it gets corroded due to sediment or mineral buildup, water may leak from the spout area.

4. Loose Parts or O-Rings

The O-ring is a small rubber ring that helps seal various parts of the faucet. If it's loose or cracked, leaks may occur near the handle. Screws and nuts may also loosen over time, causing drips.

5. High Water Pressure

If the leak only happens at certain times (like overnight), it might be due to high water pressure. This causes water to back up in your plumbing system and escape through the faucet.

Should You Try to Fix a Leaky Faucet Yourself?

If you’re comfortable with basic tools, many faucet repairs can be done DIY. Here’s a general outline:

• Turn off the water supply.

• Disassemble the faucet.

• Check and replace washers, cartridges, or O-rings.

• Reassemble and test.

However, if the leak persists or you're unsure of the faucet type, it's best to call a professional plumber.

Why You Shouldn't Ignore a Leaky Faucet

Even a slow drip can waste hundreds of gallons of water per year, costing you money and contributing to unnecessary water waste. Worse, it can indicate deeper plumbing issues or lead to mold around your sink.

Most faucet leaks are caused by worn-out parts that are relatively easy to replace. If you’re handy, a quick DIY fix might solve the issue. But when in doubt, or if the leak keeps coming back, don’t hesitate to call a pro.
