When Kitchen Drains Give You Trouble: Tips from a Hixson Service Call

At HEP, our Plumbing professionals in Hixson are proud to offer specialized Plumbing in Hixson solutions.

A Hixson Homeowner’s Clogged Sink

A homeowner in Hixson experienced a persistent kitchen sink blockage that wouldn’t clear with standard plungers or store-bought cleaners. Water backed up after every use, making simple tasks like washing dishes a chore. After calling HEP, a skilled HEP technician arrived and explained three possible approaches—from a simple clearing to a full partial rebuild of the drain line. The homeowner chose a sturdy, long-term rebuild.

This work was performed in Hixson.

How the Problem Was Solved

To restore reliable flow, the HEP technician:

Removed the old, narrow cast-iron drain line under the cabinet
Installed a center-outlet waste assembly for a smoother path under the sink
Added a P-trap and modern air admittance valve (AAV) to prevent future backups and keep odors at bay
Ran new 1.5-inch PVC piping through the cabinet floor into the crawl space
Reconnected to the existing drain line below with a flexible coupling, then provided a cleanout access with a sanitary wye and plug

Within a few hours, the sink drained freely again—and the homeowner couldn’t be happier.

5 Tips to Keep Your Drains Running Smoothly

1. Be Mindful of What Goes Down the Drain

Grease, coffee grounds and small food scraps can cling to pipe walls and form stubborn blockages over time. Use a sink strainer and funnel scraps into the trash or compost instead.

2. Upgrade Old Lines for Better Flow

Smooth, modern materials like PVC help reduce clogs. In this Hixson home, replacing aging cast-iron pipe with 1.5-inch PVC made a world of difference—and gives extra confidence against future backups.

3. Ensure Proper Drain Slope and Access

A slight downward pitch helps water carry waste through the system. The HEP technician drilled a clean hole in the cabinet floor and set the pipe at just the right angle before heading into the crawl space.

4. Consider an Air Admittance Valve (AAV)

When a traditional vent stack isn’t practical, an AAV offers a compact solution. It allows air into the line to keep water in the trap seal, preventing sewer gases from sneaking into the kitchen.

5. Schedule Routine Inspections

Even if everything seems fine, a quick once-a-year check by a HEP technician can catch minor wear before it becomes a major clog or leak.
