Why Is My Sink Leaking?

Why Is My Sink Leaking?

A leaky kitchen or bathroom sink can be more than an annoyance; it could indicate that you have a serious plumbing problem. However, before you can address the problem you need to determine the cause of the leak. Here’s a list of the most common reasons why your sink may be leaking, along with some solutions.

Leaking Drain

If the leak is occurring under the sink, the problem may lie with the sink’s drain pipe. A drain can begin to leak for several reasons: a loose connection, a damaged seal, a corroded pipe, or a clog in the drain’s P-trap.

If you’re lucky, the solution may involve simply tightening a loose connection with a wrench or patching up a seal. If the problem is due to a corroded drain pipe, the entire pipe may need to be removed and replaced, a job best left to a professional Oceanside, Ca plumber.

Damaged O-Ring

There are two kinds of leaky faucets: leaking water dripping from the spout and leaks around the base of the faucet. Leaks around the base of the faucet may result from a damaged O-ring, a small disc attached to the stem screw that holds the faucet handle in place. These leaks need to be addressed immediately to reduce the risk of water or mold damage.

Leaky Faucet

Leaky faucets are often caused by a damaged washer, gasket, or seal. A professional plumber will be able to pinpoint the exact cause of the leak and repair or replace the faucet depending on the extent of the damage.

Loose Water Supply Connections

If you’ve eliminated the faucet and drain as the source of your leak, the sink’s water supply connection is your next suspect. Sinks have two water connections for hot and cold water. A kitchen sink may have a third connection for a spray washer. These problems usually result from a loose nut, damaged pipes, or a malfunctioning washer or gasket.

Loose or Damaged Garbage Disposal Unit Connections

Your garbage disposal has two points of connection: the flange at the top of the unit that sits inside your sink and one at the bottom of the unit where it connects to the drain. Over time, the seals that secure these two connections can become compromised and begin to leak.
