Is It Time for A New Sewer Line? Spot the Signs Before It’s Late
Whether you're building a new home, replacing outdated infrastructure, or experiencing ongoing plumbing issues, knowing the signs of sewer line failure can help you avoid costly emergencies. Our trained specialists evaluate each situation thoroughly, but here are the most common signs and scenarios that call for sewer line installation:
- Persistent Drain Backups Across Multiple Fixtures: If more than one drain (e.g., tub, toilet, sink) is backing up simultaneously, this often points to a main line issue rather than isolated drain problems.
- Sewage Smells Indoors or Outdoors: A noticeable odor near drains, in basements, or in your yard could indicate a crack, loose connection, or collapse in your sewer system.
- Sudden Lawn Indentations or Wet Spots: These occur when sewage leaks beneath the surface, softening the ground and creating depressions or soggy patches, especially when it hasn't rained.
- Tree Root Intrusion: Roots infiltrate older clay or concrete pipes through joints or cracks, eventually growing large enough to restrict or completely block flow.
- Foundation Shifting or Cracking: When the soil beneath your home is saturated by a leaking sewer line, it can destabilize the foundation, leading to slab cracking or settling.
- Frequent Repairs or Jetting: If you’re calling a plumber multiple times a year to clear clogs or conduct spot repairs, you may be wasting money on a line that’s deteriorated beyond recovery.
Our team offers comprehensive diagnostics and provides a clear explanation of whether full replacement or rerouting is the most effective long-term solution. Contact us today to learn more and schedule a personalized consultation.

Our Pre-Installation Process: Strategic Planning That Guarantees Long-Term Performance
Every successful sewer line installation in Castle Hills, TX, starts with thorough preparation. We don’t just dig; we design, assess, and plan every phase based on your property’s topography, existing system condition, and municipal guidelines. Our pre-installation services include:
- Advanced Camera Inspections: We insert a high-resolution, waterproof video camera through your cleanouts or access points to examine the internal condition of your existing sewer line. This technology reveals damage, root intrusion, joint separations, or blockages and helps us pinpoint the exact location of failure without unnecessary excavation.
- Pipe Sizing and Flow Analysis: Sewer systems must be able to accommodate peak household or commercial water discharge. We calculate the required pipe size (typically 4" or 6") based on fixture units, daily usage, and potential future additions to ensure optimal flow and capacity.
- Grade and Elevation Calculations: Using laser levels and slope indicators, we measure the elevation across your property to ensure accurate calculations. Sewer lines typically require a 1/4" per foot slope for gravity-assisted flow. Any deviation from this can result in standing water or inadequate drainage.
- Soil Classification and Trench Planning: We evaluate your soil’s type (sand, clay, loam, or rock), compaction rating, and moisture content. Clay soil, for example, may need additional stabilization or trench wall reinforcement. This ensures your new line won’t shift or collapse over time.
- Utility Location and Permit Coordination: Before any digging begins, we use electronic location tools and contact 811 to identify all underground utilities. We also handle all city permitting, inspection scheduling, and documentation required by Castle Hills municipal codes.
This level of detailed planning allows us to execute precise, safe, and regulation-compliant installations with minimal disruption to your home or landscape.
Comparing Sewer Installation Methods: Trenchless vs. Traditional Dig and Replace
Different properties require different installation methods. We offer both trenchless and traditional sewer line installation options, each with its unique advantages. Here's how they compare:
Traditional Excavation (Open-Trench Installation)
This method involves digging a continuous trench along the route of the sewer line to remove the old pipe and install new piping.
Best For:
- Severely damaged or collapsed pipes beyond repair
- Major layout changes or rerouting
- Areas with unstable soil or obstructions that prevent trenchless access
Process Highlights:
- Excavation along the entire length of the line
- Removal of old pipe and proper bedding of new piping
- Installation using Schedule 40 PVC or SDR-35 pipe, glued or gasketed at each joint
- Compaction of backfill in multiple layers to prevent ground settling
Considerations
While effective, this method can be more labor-intensive and may require temporary removal of landscaping, driveways, or walkways.
Trenchless Sewer Line Installation
This modern method minimizes digging by creating small access points at either end of the existing pipe path.
Techniques Offered:
- Pipe Bursting: A bursting head is pulled through the old pipe to break it apart while simultaneously pulling in new HDPE pipe behind it.
- Cured-in-Place Pipe (CIPP): A resin-saturated liner is inserted into the old pipe, inflated, and then cured using hot water, steam, or UV light to create a new, seamless pipe inside the old one.
Best For:
- Moderately damaged or root-invaded pipes
- Preserving landscaping or pavement
- Homes where fast turnaround and minimal surface disruption are priorities
Benefits:
- Minimal excavation
- Lower labor costs
- Faster installation (typically completed in one day)
- Jointless design resists root intrusion and reduces leak points
Our technicians will assess your system and recommend the best method based on feasibility, budget, long-term durability, and compliance.
Our Sewer Line Installation Process: Step-by-Step Execution With Proven Results
At Roadrunner Plumbing & Air, we follow a detailed and refined process for sewer installation that ensures precision, performance, and minimal disruption. Here’s a full breakdown of what to expect:
- Permit Acquisition and Scheduling: We handle all paperwork, including city permits, inspection scheduling, and utility marking coordination. Our scheduling team provides realistic start and end dates, allowing you to plan ahead.
- Site Setup and Protective Measures: We arrive within a 4-hour window and use boot covers, drop cloths, plywood boards, and temporary fencing to protect your home, landscape, and hard surfaces during excavation or equipment setup.
- Excavation or Access Creation: Depending on the installation method, we either dig a full trench (traditional) or two access holes (trenchless). Shoring systems are used for deep trenches to maintain job site safety.
- Pipe Installation or Replacement: Pipes are installed with precise slope and alignment. Connections are joined using solvent welding or mechanical gaskets, and pressure-tested according to Uniform Plumbing Code (UPC) standards. Bedding is laid using compacted sand or pea gravel to protect the pipe and prevent sagging.
- System Testing and Final Camera Inspection: We perform hydrostatic testing (or air testing in cold weather) to verify the integrity of the line. A final video inspection confirms correct placement, joint integrity, and flow consistency before backfilling.
- Backfill and Site Restoration: Trenches are filled in stages and compacted to prevent future settling. If your project includes landscaping or pavement, we restore those surfaces to match their original condition as closely as possible.
- Final Walkthrough and Warranty Activation: We review the completed system with you, explain maintenance guidelines, and issue all warranty documentation. Our worry-free warranty and 100% satisfaction guarantee offer long-term peace of mind.
Our same-day service availability and well-equipped trucks mean we’re prepared for unexpected variables, ensuring your project stays on time and on budget.
