How Long Do Relined Pipes Last in Residential Properties?

Traditional pipe repair methods often mean messy, costly yard excavations. Thankfully, pipe relining offers a modern solution that saves your lawn and your budget. This process installs a new pipe inside the old one, but a common question we hear at Speedy Rooter Plumbing is: “How long can I expect this repair to last?” We specialize in solutions like trenchless pipe lining in Crozet, VA, and have clear answers about the longevity of this innovative plumbing fix.

The Longevity of CIPP Pipe Lining

CIPP pipe lining creates a new pipe within the old, damaged one. The process involves inserting a flexible liner coated with a special epoxy resin into the existing pipe. Once in place, the resin cures, hardening to form a smooth, seamless pipe.

When performed correctly by qualified pipe lining companies, a relined pipe is not a temporary patch. It is a structural repair designed to withstand the pressures and flow of a typical residential plumbing system. The epoxy materials used are incredibly tough and have a proven track record. This process avoids the high cost and disruption of completely replacing a buried line.

Expected Lifespan for Relined Pipes

Generally, homeowners can expect a relined pipe to last for 50 years or more. This long lifespan is one of the main reasons pipe relining has become so popular. The new pipe, often stronger than the original, is resistant to common issues that cause old pipes to fail. Since the liner is non-metallic, it does not rust or corrode. It also eliminates small cracks in the old pipe, which prevents tree roots from infiltrating the line.

The longevity is dependent on a few factors: the quality of the installation, the condition of the original host pipe, and the materials used. For example, lines made of certain materials like Orangeburg may require special preparation, but generally, relining works well on various pipe types. Homeowners dealing with aging but stable cast iron pipes often choose cast iron pipe lining because it preserves the historical structure of their property while addressing serious plumbing failures.

Protecting Your Sewer Line Investment

While a relined pipe offers decades of reliable service, homeowners should still practice good plumbing habits. Avoiding flushing non-biodegradable items and scheduling routine inspections can help maintain the integrity of the line. The new liner dramatically reduces the chance of clogs and backups, but nothing can completely stop solid grease or foreign objects from causing problems. Getting routine check-ups on your entire system provides early detection for any potential issues, though the liner itself needs very little maintenance.

FAQs

Q: What diameter pipes can be relined?

A: Pipe relining works for a wide range of pipe sizes, typically from small lateral lines (4 inches) up to large main sewer lines (many feet in diameter). For residential applications, the process is very effective on the standard 3-inch or 4-inch drain and sewer lines.

Q: Can a pipe be relined if it has a large break or a collapsed section?

A: Pipe relining works best for pipes that are structurally sound but have cracks, leaks, or root intrusion. If a section of the pipe has completely collapsed or has large missing pieces, a small, targeted excavation may be needed to replace that segment before the rest of the line can be relined.

Q: Does pipe relining reduce the pipe’s internal diameter, affecting flow?

A: Yes, pipe relining reduces the pipe’s diameter slightly because of the thickness of the new liner. However, this small reduction generally does not impact flow rate because the new epoxy surface is incredibly smooth. This smooth interior reduces friction and often improves the overall flow compared to the old pipe interior.
