Residential Cast Iron Sewer Pipe Replacement in Murphy, TX
Underground Pipe Replacement Services for Murphy Homeowners
If your Murphy home was built before 1986 — especially in neighborhoods within ZIP code 75094 — there’s a strong chance it still has cast iron sewer piping beneath the slab. These pipes have a limited lifespan and are known to corrode, crack, or shift over time, putting your home at risk of costly plumbing failures.
At In-House Plumbing Company, we don’t offer general plumbing — we focus solely on cast iron pipe replacement. Our complete underground pipe replacement services are designed to replace aging cast iron systems with high-quality PVC piping that’s built to last.
Why Cast Iron Pipes Fail in Murphy
Like many North Texas communities, Murphy sits on soil that expands and contracts with changing moisture levels. That soil movement, combined with decades of corrosion, leads to serious pipe problems, including:
- Rusted and flaking cast iron walls that block flow
- Cracks that let in roots and debris
- Pipe joints that separate or shift due to foundation movement
These issues can’t be permanently fixed with spot repairs. We provide full pipe replacement services because that’s the only way to solve the root problem.
