Austin Sewer & Drain Installation for a Future-Ready Bathroom

The homeowner in central Austin was getting ready for a bathroom remodel when signs of trouble started showing up in the plumbing – slow drains and worries about what might be happening under the slab. Radiant Plumbing & Air Conditioning’s Austin drain installation team was called in to inspect the sewer and drains, and we found a damaged main trunk line and cracked p-trap that needed more than a quick fix. We installed new PVC sewer piping, corrected the problem areas, and prepared the system for a smooth, worry-free remodel down the road.

Job Overview

  • Location: Austin, TX
  • Client Type: Residential
  • Scope: Replace damaged main sewer trunk line and p-trap, and rough-in drainage for a future tub remodel
  • Equipment Installed: 60′ of 3″ Schedule 40 PVC drain piping, PVC p-trap, code-approved fittings and connections
  • Additional Work (if any): Sewer line diagnostic, trenching and excavation, reconnection to existing system, system testing and inspection
  • Why It Mattered: To stop current and future sewer issues and protect the homeowner’s investment in a planned bathroom remodel

What We Found

During our inspection, we found that the existing main sewer trunk line under the home had a “belly” – a low spot where wastewater was collecting instead of flowing out smoothly. The p-trap on the line was also cracked, which can lead to leaks, sewer odors, and a higher risk of backups inside the home.

We also discovered a broken double sanitary fitting where future fixtures, like a new tub, would need to connect. For a homeowner investing in a bathroom remodel, tying into an old, failing sewer line is a recipe for problems later. The drain system needed to be corrected now so the remodel could move forward on a solid foundation.

The Solution

To get the home ready for both everyday use and the upcoming bathroom remodel, our drain team started by opening the ground to reach the damaged section of the sewer line. Once exposed, we removed the cracked p-trap, the low spot in the pipe where water was collecting, and the broken fitting that would have caused problems later. We then installed about 60 feet of new PVC piping, making sure it had the proper slope so wastewater could flow out smoothly. A new p-trap and connections were added in the right place to support the homeowner’s future tub installation. After reconnecting the new line to the existing system, we tested everything to ensure water moved through it cleanly with no leaks. Once the repairs were complete, we closed up the area and restored the space so the homeowner could move forward with confidence. By rebuilding this essential section of the sewer line, we created a solid, long-lasting foundation for the home and the remodel ahead.

The Results

With the new sewer and drain installation in place, the homeowner now has a properly sloped, leak-free main line that keeps wastewater moving out of the home the way it should. The cracked p-trap and failing fittings were removed, reducing the risk of sewer odors, leaks, and messy backups.

Just as important, the system is now set up to support the planned bathroom remodel. The future tub and fixtures can be tied into a strong, modern drain system instead of an aging, problem-prone line. The homeowner can move forward with their project with confidence, knowing the hidden plumbing is ready to support it.
