A homeowner in Cedar Park was dealing with ongoing drain problems, even after having their septic system serviced. One bathroom had a tub and toilet that wouldn’t drain, and multiple drain clogs were reported throughout the home. After diagnosing the issue, our team recommended a full drain line installation using a tunneling method to protect the home’s foundation. The result was a long-term solution that restored proper drainage and peace of mind.
Job Overview
- Location: Cedar Park, TX
- Client Type: Residential
- Scope: Diagnose drain issues, excavate via tunneling, install new drain line, reconnect system
- Equipment Installed: PVC drain piping system (schedule 40)
- Additional Work (if any): Branch line repair, bathroom drain clearing, system testing
- Why It Mattered: Recurring clogs were disrupting daily life and risking further plumbing damage
What We Found
When we arrived, the homeowner explained that their septic tank had just been pumped, but the drains were still not working properly. The bathtub and toilet in one bathroom were completely backed up, and other drains in the home were slow or clogged.
After inspecting the system, we found that the issue wasn’t just a simple blockage. The home’s existing drain lines, likely original to the house, showed signs of wear and buildup from years of use. In some areas, the pipes were no longer allowing proper flow, which caused repeated backups even after cleaning attempts.
The Solution
To provide a lasting fix, we recommended a full drain line installation. Instead of digging through the home’s slab, our team used a tunneling method beneath the foundation. This approach allowed us to access and replace the damaged pipes while minimizing disruption to the home.
We carefully excavated a tunnel under the affected areas, removed the failing sections of pipe, and installed new PVC drain lines designed for long-term durability. Our team then reconnected all plumbing fixtures, ensured proper slope for drainage, and performed thorough testing to confirm everything was flowing correctly.
Each step was completed with attention to detail, including secure fittings, proper alignment, and final quality checks to ensure the system would perform reliably moving forward.

The Results
With the new drain line installed, the homeowner now has a system that drains properly and consistently. The bathroom fixtures are fully functional again, and the risk of recurring clogs has been significantly reduced.
This solution not only resolved the immediate issue but also helped protect the home from future plumbing problems. The homeowner can now use their plumbing system with confidence, knowing it was rebuilt to last.
