Most of our work is commercial. We know a blocked line means a closed kitchen, an angry tenant or a stalled job site, so we diagnose fast and fix the cause, not the symptom.
Hydro jetting for kitchen lines and grease interceptor lines, camera checks to find recurring clogs, and maintenance schedules sized to your volume.
Trusted by quick-service restaurants in El Paso, including:


Recurring backups across units? We camera the line and show you the real cause before anyone digs. →
Sewer and drain work with clear documentation your facility team can file. →
Camera inspections, pipe locating and trenchless plumbing repairs for the underground part of your scope. →
Main line backing up at home? Same trenchless plumbing, same camera-first process, same honest answer. →
Modern trenchless plumbing equipment for cleaning, inspecting and repairing underground drain and sewer lines, from a single restaurant to a full apartment complex.

High-pressure water scours grease, hard-water scale and roots off the pipe wall. A snake pokes a hole through the clog. Jetting cleans the whole line, so the clog doesn’t come back next month.

Tell us what’s happening. We’ll start with a camera and tell you what the line actually needs.
No guessing. You see what we see, you understand your options, and you get a record of the work when we’re done.
A high-resolution camera goes in first to find the exact problem and where it is.
You get photos, video and a plain-English explanation of what we found and your repair options.
Jetting, lining or a trenchless plumbing replacement. Whatever solves the cause, not just the symptom.
We check the line again after the work and document the result for your records.
Plenty of plumbers guess. We document. That’s why property managers and restaurant operators keep calling us back for trenchless plumbing.

After each inspection you receive the footage, still photos of each problem, and our recommendation in writing. Share it with your owner, your insurer or your contractor.
If a line only needs cleaning, we won’t sell you a replacement. The camera decides, not the invoice.
We work with Spartan Tool and attend the WWETT Show every year to stay current on inspection and cleaning technology.
Responsible Master Plumber License #16347. We carry commercial auto, general liability, pollution and umbrella coverage, and provide a Certificate of Insurance on request.
Scheduled hydro jetting and camera checks for restaurants and multi-unit properties. Small buildup gets cleared on your calendar, not in the middle of a Friday dinner rush.

Plumbing runs in our family. Our grandparents were plumbers, our father was a plumber, and we grew up on job sites learning to do it right the first time. Today U.T. Trenchless is woman-owned and family-run, with the same hands-on approach and a lot more technology.
We sponsor high school football and basketball teams and support the Locomotives Youth Soccer Camp.
You deal directly with the people doing the diagnosis, not a call center.

Straight answers on drain cleaning, camera inspections, pipe lining and sewer repair, written by the third generation plumbers who do the work across El Paso, Horizon City, Socorro and Las Cruces.

Smoke, dye and camera tests each answer a different question about your sewer. Here is what each one finds, what it misses, and how to pick the right test for your symptom.

A sewer smell means gas is slipping past a trap, seal or vent. Here are the common causes, what hydrogen sulfide means for your health, and how smoke testing pinpoints the leak.

Sewer smoke testing pushes harmless vapor through drain and vent pipes to reveal leaks. Here is what the smoke is made of, why dry traps let it in, and how city programs differ from a private test.

Drawings rarely match what is in the ground. Here is why mapping sewer, water and gas lines before a remodel, addition or trenchless repair saves money and rework.

Texas 811 only alerts utilities to mark the lines they own. Your sewer lateral, irrigation and gas lines to outbuildings are private, and here is how to get them located before you dig.

Plumbers find buried pipes by tracing a signal, not the pipe. Here is how sonde cameras, electromagnetic locators, tracer wire and ground penetrating radar work, and where each one falls short.

Dye testing proves where water really goes. Learn how El Paso property owners use it to find leaks, cross connections and illegal hookups, and where it falls short.

Sewer flow monitoring records how much wastewater moves through a pipe and when. Here is how El Paso commercial properties use it to find stormwater leaks and prove capacity.

A plumbing dye test uses a safe tracer dye to prove where water goes. Here is when El Paso homeowners need one, what the dye is, and what the test cannot tell you.

In almost all cases, the answer is yes. Cured-in-place pipe (CIPP) lining and pipe bursting are trenchless methods that are particularly beneficial for aging or crumbling pipeline systems. Clients do not have to worry about tearing things apart for the service to be installed, thanks to revolutionary processes that enable maintenance of existing infrastructure.
