Chattanooga Kitchen Sink Leak Repair: Tips from HEP Technicians

Discover reliable Plumbing solutions in Chattanooga with our guide to Plumbing in Chattanooga.

The Case of the Dripping Sink

A homeowner in Chattanooga noticed water pooling under her kitchen sink every time she drained the basin. The culprit? An old dishwasher drain connection that had rotted away and allowed leaks from the drain piping. Concerned about potential water damage, she reached out to HEP for help.

How It Was Solved

A HEP technician arrived on site to assess the leak. Rather than repairing a long-unused dishwasher hookup, the decision was made to remove the old drain barb completely and simplify the plumbing. The steps included:

  1. Safely detaching and removing the deteriorated dishwasher drain fitting.
  2. Installing a new double-sink drain kit onto the existing S-trap under the sink.
  3. Replacing the center waste outlet and tailpieces with fresh components for a reliable seal.
  4. Performing a thorough leak test—no drips, no worries.

Here’s a look at some of the materials used during the replacement:

Tips for Preventing Under-Sink Leaks

Keeping your sink drain healthy isn’t just about fixing problems—it’s about avoiding them in the first place. Follow these homeowner-friendly tips:

  • Inspect Regularly
    Open cabinet doors and look for damp spots or mold every few weeks.

  • Remove Unused Connections
    If a dishwasher or appliance goes out of service, cap or remove any leftover hoses and fittings to prevent future rot.

  • Use Quality Parts
    Investing in a good drain kit and new tailpieces ensures a snug, long-lasting seal.

  • Keep It Dry
    Wipe down pipes and fittings to catch minor drips before they become major leaks.

  • Know Your Shut-Off Valve
    Locate and test the valve under the sink once a year. Quick access can save you from extensive water damage.

Why Professional Help Matters

Simple drain concerns are one thing, but corroded or complex fittings call for expert attention. Our HEP technicians have the right tools, know-how, and genuine parts to handle routine maintenance and more involved repairs alike. For homeowners in Chattanooga, a prompt service call can turn a frustrating drip into a hassle-free fix—keeping cabinets dry and daily life flowing smoothly.
