Sewer Scope Before You Buy: Clay Sewer Lines in Older Englewood and Littleton Homes

If you are in the process of purchasing a home in Englewood (zips 80110, 80113), historic Downtown Littleton, or Sheridan built between 1920 and 1968, your primary underground sewer lateral is constructed of vitrified clay tile pipe or vintage unlined cast iron.

While general real estate home inspectors inspect sinks, test toilets, and check exposed basement piping, standard pre-purchase home inspections completely omit the underground sewer pipe connecting your home to the municipal sewer main in the street. A dedicated sewer camera scope inspection is the only reliable way to evaluate the physical condition of this critical underground infrastructure.

Vitrified clay pipes were manufactured in short three-foot segments joined by cement mortar, tar, or oakum packing. Over 50 to 80 years of service, Front Range expansive bentonite clay soils naturally swell during spring snowmelt and shrink during dry summer heat waves. This relentless ground movement cracks brittle cement mortar joints, shifting pipe alignments.

Moisture and warm nutrient-rich vapor escaping from these cracked joints act as a homing signal for the root systems of mature neighborhood trees, including silver maples, green ash, and cottonwoods. Roots penetrate joints as hair-thin filaments, rapidly expanding into dense root balls that snag toilet paper, waste solids, and grease until sewage backs up into basement showers and floor drains.

A licensed plumbing technician inserts a self-leveling, high-definition fiber-optic sewer camera through the main sewer cleanout, recording the line in real time all the way to the city main tap. The camera precisely locates pipe defects, measuring exact footage and depth from the surface.

Key defects uncovered during an Englewood sewer scope include: offset joints where pipe sections have shifted out of alignment, root masses choking flow, low spots (bellies) where sagging pipe collects standing water and solids, and channel rot or pipe shears caused by soil settlement. Having this video evidence during your real estate inspection contingency window gives you crucial leverage to negotiate seller concessions or complete repairs before closing.

If a sewer scope identifies severe root intrusion, sheared clay tiles, or persistent bellies, replacement is essential. Fortunately, homeowners no longer need to excavate a massive trench across their front lawn, driveway, and landscaping.

Modern trenchless pipe bursting utilizes a heavy hydraulic pulling unit that pulls a hardened conical bursting head through the deteriorating clay pipe. The head fractures the old pipe outward into surrounding soil while simultaneously pulling a seamless, leak-proof high-density polyethylene (HDPE) pipe in its place. The resulting line is completely joint-free, immune to future tree root penetration, and engineered to last 100+ years.
