What Causes Leaks Under The Sink?

Under-the-sink leaks can be downright frustrating. But beyond that, they can do a lot of water damage. Preventing this possible water damage isn’t always straightforward, especially for homeowners who lack plumbing experience.

To help, here are some of the most common causes of water leakage under the sink and suggested solutions.

Common Causes of Leaks Under the Sink

1. Advanced Corrosion

Over time, rust can eat away at the pipes in your home and create cracks for water to escape through. If your plumbing is over 30 years old, your pipes are at a higher risk of corrosion. We recommend replacing your pipes with PEX.

PEX pipe is cost-effective, flexible, durable, and easy to install, making it a popular choice versus Copper – a soft metal that tends to leak.

Since there are several different manufacturers of PEX, it’s crucial to install only that manufacturer’s connectors and fittings.

If you mix and match materials, you will not only void your warranty, but you’ll end up right where you started – with leaky pipes and water damage.

2. Improper Valves

In addition to ensuring your home has healthy pipes, make sure you use all brass valves. Brass has long been used in homes for plumbing thanks to its numerous advantages, including:

  • Corrosion-resistance
  • versatility
  • Excellent conductivity and ductility

Avoid self-piercing saddle valves, as they’re prone to leakage. Older valves, such as the cheaper multi-turn valves, are made with plastic and require several turns of the stem to shut off the water flow.

As these valves age and rust, they can leak when used to shut the water supply off. With that being said, stay clear of plastic multi-turn valves.

3. Worn Out Disposal

If the leak isn’t from the pipes, you’ll need to perform some additional troubleshooting. If you identify water coming from bottom, the likely culprit is either a worn out internal seal or loose drain.

If it’s a busted seal, a new garbage disposal is likely your best bet. The good news is that disposals are inexpensive and can last you 5 to 10 years.

To fix the loose drain, tighten the metal clamp with a screwdriver to see if it stops the leaking.

Run a tissue over all surfaces

If the source of the water continues to be a mystery, touch all of the supply and drain lines with a tissue to detect moisture on the lines. While you’re under the sink, touch the supply lines where they connect to the faucet.
