A New Homeowner’s Challenge and How It Was Solved

When Jane and Mark moved into their recently purchased home in Knoxville, they discovered a troubling gurgle in the toilet whenever someone showered—and even feared a full sewer backup. At the same time, moisture was dripping inside their attic from the HVAC condensate line. They reached out to HEP, hoping for a quick fix and peace of mind.

HEP technicians arrived promptly, first confirming that drains in sinks and tubs flowed freely, which ruled out a simple clog. Next, a camera inspection revealed an aging cast-iron branch under the porch and a hidden bend that was causing slow drainage. Over two days, our team carefully removed the old porch decking, dug along the sewer route, cut out the corroded pipe, and connected new 4" PVC with proper slope, cleanouts, tracer wire and gravel bedding. Meanwhile, our HVAC crew replaced the old condensate pump, ran a new drain through the wall, and added blown-in insulation for energy savings. The final step was scheduling the required 811 locate, passing inspection, backfilling the trenches, seeding and strawing the yard—leaving the property as tidy as we found it.

Below, we share homeowner-friendly tips inspired by this case so you can spot potential issues early and know what to expect when professionals are on the job.

1. Get a Full System Check Before You Move In

Before unpacking boxes, it’s wise to have both Plumbing and HVAC systems inspected. Hidden pipe damage or a misplaced fitting can cause recurring backups or leaks.

• A pipe-inspection camera lets technicians see inside lines without digging or major demolition.
• It helps pinpoint cracks, roots or improper fittings that lead to slow drains and surprises.

2. Proper Sewer Line Replacement Matters

When a main line is beyond simple snaking, full replacement may be the only lasting solution. Watch for signs like persistent gurgling, sewage odors or patchwork repairs from previous owners.

• PVC pipe is durable, resistant to root intrusion, and simpler to slope correctly compared to older materials.
• Gravel bedding under the pipe helps support it and improves drainage around it.

Our technicians laid new sewer pipe on a bed of gravel to ensure proper drainage and long-term reliability.

3. Install Cleanouts and Tracer Wire for Easy Maintenance

Adding access points along your sewer line saves future service fees and downtime. Tracer wire makes locating buried lines quick and precise.

4. Don’t Overlook Your HVAC Condensate Drain

An overflowing condensate line can damage ceilings and insulation. A well-installed drain and proper attic insulation keeps your system running efficiently.

HEP technicians replaced the old drain pump, added a new line through the wall, and topped off the attic with blown-in insulation.

5. Yard Restoration: The Finishing Touch

After heavy digging, your yard needs attention. A protective layer of straw helps seed take root and prevents erosion.

Following installation, the trench was backfilled, seeded and strawed—leaving the lawn ready for spring growth.

Bonus Tip: Always Call 811 Before Digging

State law requires you to notify 811 before any excavation. This free service marks underground utilities so you avoid cutting water, gas or power lines.

By combining careful inspection, quality materials and thoughtful restoration, HEP technicians deliver lasting solutions and protect your home investment.
