Leaks Under Your Sink? DIY Plumbing Checks Before Calling the Professionals

Posted May 6, 2026

Identifying minor leaks around the home

In this article, you'll learn:

  • Regular plumbing checks help catch small leaks early, preventing costly repairs and water damage
  • Simple DIY steps like tightening fittings and replacing washers can maintain your system and reduce water waste
  • Knowing when to call a professional ensures more serious plumbing issues are handled properly

Your home’s water system is integral to the overall health and function of the home itself. Conducting regular plumbing checks helps prevent unexpected issues that can cause damage to your wallet and your plumbing. Plus, regular maintenance is simple and can be conducted in a matter of minutes.

Homeowners can conduct minor plumbing checks around the house, like looking for small leaks under their sinks and around outdoor hose connections. Tightening the fittings around sinks and faucets in the home can proactively address drips early before they get worse.

Why Regular Plumbing Checks Are Important

Homeowners conducting regular plumbing checks around the house can benefit from:

  • Identifying minor leaks before they become major, unexpected repairs
  • Preventative damage tot heir cabinets, flooring, and the foundation of their home
  • Lower water bills due to no unnoticed drips leading to increased water usage
  • The peace of mind that comes with preventative maintenance

Checking Under Your Sinks for Hidden Links

Here is what to look for and what you can do when inspecting under your sinks for hidden leaks:

  • Moisture or puddles appearing randomly in your kitchen or bathroom
  • Water stains on your cabinets or warped cabinetry
  • Strong smells and musty odors

As a non-plumber, what you can do is fairly limited but can be effective: tighten loose fittings by hand or wrench, replace worn washers if needed, and dry the area and continue to monitor it for recurring moisture.

Checking for Plumbing Issues Outside the House

Common problem areas outside the home for leaks are with spigots, hose connections and threads, and split or worn hoses. If there is unexpected dripping when the hose is connected or disconnected, standing water near the foundation, or visible cracks or corrosion then it might be time to address the issue.

Here’s what you can do:

  • Securely tighten the connections
  • Replace rubber washers inside the house
  • Swap out damaged hoses or fittings with new ones

It’s important to address problem areas early to prevent long-lasting damage, higher water bills, and to ensure the longevity of your home’s plumbing system.

When to Call a Plumbing Professional

Oftentimes, DIY fixes are not enough and while they may temporarily address the issue, a professional plumber may be needed to address:

  • Persistent leaking
  • Damaged pipes
  • Water damage around the leak area
  • Low water pressure
