Ontario is really two cities where plumbing is concerned. North of the 60 you have the historic core along Euclid Avenue and the downtown grid, with homes from the 1900s through the 1940s sitting on original clay and cast iron. South of the 60 you have Ontario Ranch, built on former dairy land in the last fifteen years. In between, and around the airport, sits one of the densest concentrations of warehouse and distribution property in the country.
Each of those has a sewer problem, and each has the same traditional fix: excavation, with a trench through a historic front yard, a new parking lot, or an active truck court. Pipelining is the alternative. Perry Plumbing and Pipelining rebuilds failed lines from the inside using a structural epoxy liner installed through an existing cleanout. Family owned since 1977. Call (619) 472-2112 or schedule an inspection.
What Trenchless Pipelining Is
Cured-in-place pipe lining rehabilitates a damaged sewer or drain without removing it. An epoxy-saturated liner is drawn into the pipe, inflated against the interior wall, and cured until it hardens into a seamless, corrosion-resistant new pipe formed inside the existing one.
Because it’s jointless, roots can’t enter and groundwater can’t infiltrate. Because it’s smooth, flow often improves on the pre-failure condition. Expected service life is 50 years or more. Full details on our trenchless pipelining services page.
Why Ontario Lines Fail
- Century-old clay and cast iron downtown. Homes along the Euclid corridor and through historic Ontario were plumbed with vitrified clay and cast iron generations ago. Clay cracks and separates at every joint. Cast iron corrodes from the inside until the bottom of the pipe channels out and solids start catching.
- Mature street trees. The Euclid Avenue median and the old neighborhoods around it carry decades of established canopy. Those root systems find leaking clay joints reliably, and by the time you notice symptoms the intrusion is usually well developed.
- Heavy truck loading. Around the airport, Ontario Mills, and the logistics corridor, building drains and laterals under truck courts, loading areas, and drive aisles take axle loads far beyond design. Repeated loading deforms and eventually crushes shallow pipe.
- Grease loading in commercial kitchens. Restaurants and food service along Fourth Street, Milliken, and the Mills area push heavy FOG loads into building drains where it congeals, hardens, and steadily narrows the line.
- Orangeburg pipe. Properties developed from the late 1940s through the early 1970s sometimes have this tar-and-fiber pipe, which flattens into an oval as it ages and eventually collapses.
Signs It’s Time for an Inspection
- Main line stoppages that return every few months despite repeated cabling or jetting
- Multiple fixtures backing up at once rather than one slow drain
- Toilets gurgling when other fixtures drain
- A commercial kitchen line that reloads faster every time it’s serviced
- Sewer odor inside the building or over the line route outside
- Depressions, cracking, or soft asphalt over a buried line in a lot or drive aisle
- Rust-colored or gritty debris in a tub or floor drain, a classic cast iron symptom
Those symptoms fit several very different problems. A sewer camera inspection tells you whether you’re dealing with roots, grease, a crushed section, or a line that only needs cleaning.
Our Process
1. Inspect and Scope
We camera the line, identify the material and every defect, and record depth and distance so the scope of work is exact rather than estimated.
2. Clean, Descale, Degrease
Hydro jetting and mechanical cutters clear roots, scale, and hardened grease. On a badly loaded commercial line this alone can restore substantial diameter.
3. Install and Cure
The epoxy liner is drawn into place, inflated against the host pipe, and cured into a structural pipe sealing every joint and crack across its length.
4. Verify and Report
We re-camera the finished line and provide footage and a written report for your records, your property manager, or your association.
Residential, Commercial and Industrial Pipelining
For homeowners in historic Ontario, lining means the trench never happens: no cut through a period front walk, no damage to a mature parkway tree’s root zone, no jackhammered slab for an under-slab failure.
For warehouse, distribution, and retail property, the argument is operational. Trenching a building drain means taking a section of floor, dock, or lot out of service, and in an active facility that cost far exceeds the plumbing itself. Lining works through cleanouts, so the floor stays intact and dock doors keep running. We schedule around operating hours, including overnight and weekends. We also offer large diameter sewer inspection for facilities assessing a system before committing to anything.

Frequently Asked Questions About Pipelining in Ontario
My home downtown is from the 1920s with original clay. Line it or replace it?
Usually line it, assuming the clay is cracked rather than collapsed. Clay’s core problem is that it’s jointed every few feet and every joint eventually leaks and admits roots. A liner converts the whole run into one continuous jointless pipe, which fixes the underlying condition rather than the current symptom. Replacement achieves something similar but requires trenching a yard, walkway, and possibly the street.
Can you line a warehouse or distribution building drain?
Yes, and it’s a large part of what we do in this corridor. Building drains, mains, and larger-diameter lines under slab and under paving are all candidates. The alternative in a distribution facility is saw-cutting and trenching the floor, taking racking and dock positions offline for days. Lining avoids that entirely.
Will my restaurant or store have to close?
Rarely for a full day. Drains in the affected section are unavailable during the cure, typically a few hours, and we routinely work overnight or on your slowest day. Give us your service hours when you call and we’ll build the schedule around them.
Does lining help with a chronic grease problem?
Meaningfully, yes. Degreasing restores full diameter, and the cured liner is smooth and non-porous, so grease has far less to cling to than the rough interior of corroded cast iron. It doesn’t eliminate the need for interceptor maintenance and periodic jetting, since nothing does, but it substantially slows how fast the line reloads.
Trucks run over our line daily. Can a crushed section be lined?
It depends how far it’s gone. A pipe that’s deformed but still has a continuous open path can often be cleaned and lined, and the cured liner adds structural strength the old pipe had lost. A fully crushed or collapsed section has to be excavated and replaced first, then the remainder can be lined. The camera settles it quickly.
My house in Ontario Ranch is nearly new. Is any of this relevant?
Much less so, and we’ll tell you that rather than manufacture a concern. Newer PVC installed to current code should have decades of life ahead of it. Where problems do turn up in new construction, they’re usually installation issues such as debris left in the line, a poorly bedded section, or an improper grade, and those show up early. If you have recurring backups in a house under fifteen years old, a camera inspection is worth doing precisely because the cause is probably something specific and fixable.
Do you handle HOA or shared laterals?
Yes. Shared lines are common in Ontario’s condominium and townhome communities, and lining is often the preferred option because it doesn’t require closing walkways or parking or trenching through common landscaping. We provide the camera footage and written scope that boards and management companies need, including documentation of exactly where the defect sits, which is usually what settles the question of responsibility.
Do you offer emergency service in Ontario?
Yes, 24 hours a day. Call (619) 472-2112 for an active backup at a home, commercial building, or industrial facility.
