Why is My Kitchen Sink Leaking 6 Surprising Reasons

Do you know about "Why is My Kitchen Sink Leaking?" A leaky sink can be a real annoyance in any home. The constant noise and puddles are bothersome. Moreover, not knowing the cause makes it even more frustrating.

When your sink leaks, you must decide whether you can fix it yourself or need a professional.

Why is My Kitchen Sink Leaking

If your kitchen sink is leaking, read this blog. It covers six reasons why it might be happening.

1. Corroded Valve Seat

The valve seat in your kitchen sink links the spout and faucet for compression. Too much water there can lead to corrosion. Corrosion occurs when materials break down due to a chemical reaction. It's a common issue in plumbing. A corroded valve seat will cause leaks. To prevent this, clean it with help from a professional.

Loose Water Supply Connection

A leak under the kitchen sink could signal a problem. Now, it is especially true for a constant leak. Most kitchen sinks have two water supply lines. Yet, sinks with sprayers can have three. All these lines are prone to leaks, leading to sink issues. You might notice these leaks once things under the sink are wet. A leak from a water supply line often results from a worn-out gasket or corrosion. Replacing the gasket or tightening the connection can fix the leak.

2. Damaged O-Ring

The O-ring is a small disc on your faucet's stem screw that secures the handle. Over time, it can wear or loosen, leading to kitchen sink leaks. Your faucet might drip around the handle. To fix this, replace the O-ring. But if you need more clarification, consult a plumber to confirm the issue.

3. Faucet Leak

The leaking faucet is easy to spot. You might see puddles on the sink when the faucet runs. Another sign is water under the sink, which you can see below the counter. If you suspect a leak, check the washers and gaskets. Replace worn items.

4. Clogged P-Trap

A P-trap is a curved pipe under a sink. It stops bad smells. Additionally, it hides clogs and leaks. Over time, gunk, food, or debris can build up and block drainage. This blockage could lead to a leak. Clearing the trap should stop the leak. Replace the P-trap. If you notice damage to the item, take this action.

5. Drain Leak

Drains usually use putty to avoid leaks. Thin or drying putty can cause a leak. An old, used drain might also leak. Calling a plumber for a proper replacement is wise in these cases.

Worn Washers

The main reason for a sink leak is often a worn-out washer. When you use the faucet, the washer rubs against the valve seat, causing friction. If this is the issue, you'll notice leaks near the spout. Replace the washer, especially for compression faucets, to fix it.

6. Excessive Water Pressure

High water pressure is nice for showers but risky for leaks. Strong pressure can damage pipes, increasing the risk of problems.

1. The water pressure is so high that it is extreme. Your pipes may burst.
2. In a less extreme situation, low water pressure may cause occasional leaks. It often happens after water flows.
3. If you see this change start, you may need a plumber to test your water pressure. They will make the necessary adjustments.
