Southern Utah's Most Powerful Drain-Cleaning Solution
Marlin Plumbing's hydro-jetting service pairs professional-grade water pressure with a camera-first diagnostic approach. Before we jet any line, we use sewer camera inspection to identify the exact blockage type and confirm pipe integrity — ensuring we're applying the right solution without risking damage. After jetting, we run the camera again to document the restored pipe.
For homeowners dealing with persistent drain problems, hydro-jetting is the step that breaks the cycle. Most of our repeat customers report 18 to 36 months of problem-free flow after a hydro-jetting service, compared to 3 to 6 months of relief from repeated snaking. It's not the cheapest call — but it's usually the last call for a long time.
When Snaking Is Not Enough
A drain snake pokes a hole through a clog. Hydro-jetting obliterates it — and scours the pipe walls clean at the same time. We feed a flexible hose with a multi-directional nozzle into your drain line and blast water at up to 4,000 PSI, cutting through grease columns, mineral deposits, tree roots, and compacted debris that have built up over years. The result is a pipe that flows like new, not just one that drains a little faster.
St. George's water is among the hardest in the country at 15–25 grains per gallon. That calcium and magnesium doesn't just attack water heaters and fixtures — it accumulates inside drain pipes too, narrowing the bore over time. Combined with the cooking grease that solidifies quickly in our summer heat, blockages here are denser and more stubborn than in most markets. Hydro-jetting is the only method that fully restores pipe capacity rather than temporarily reopening it.

Know the Warning Signs
Signs You Need Hydro-Jetting
Catching these early prevents a small issue from becoming a costly emergency.
If multiple fixtures drain slowly at the same time — sinks, showers, floor drains — the blockage is in a main line, not an individual trap. Hydro-jetting clears the entire run, not just the accessible section.
Water backing up into a bathtub when you flush a toilet, or into a floor drain when you run the dishwasher, indicates a severe partial or complete blockage downstream. This is a hygiene hazard that warrants urgent service.
Grease and organic buildup inside drain lines off-gas hydrogen sulfide. If you smell rotten eggs or sewage without an obvious source, a gunked-up main drain is a likely culprit.
If you've had a plumber snake the same line twice in 12 months and it's slow again, you're treating symptoms. Hydro-jetting restores the pipe to full bore and typically resolves recurring blockages for 1–3 years.
Air displaced by a partial blockage escapes through the nearest wet trap, creating a gurgling sound. This is an early warning sign that your drain line needs professional attention before it becomes a full stoppage.
Raw sewage at a basement or garage floor drain is a plumbing emergency. Shut off water to the home and call immediately — this indicates a main sewer line blockage.
Local Expertise
Why St. George Drains Need More Than a Snake
Washington County's water hardness — consistently 15–25 grains per gallon depending on the source — is among the highest in Utah. While most homeowners focus on the visible effects (spotty dishes, short water heater life), the slow accumulation of calcium and magnesium deposits inside drain lines is less obvious but equally damaging. Over 5–10 years, a drain pipe can lose 30–50% of its interior diameter to mineral scale alone, compounding the grease and soap scum buildup that every household drain sees.
The desert heat compounds the problem. Grease that might flow freely in a cooler climate solidifies quickly in St. George's 110°F summer heat, especially in outdoor drain runs exposed to direct sunlight. Neighborhoods like Little Valley and Sunbrook, with their newer construction and longer pipe runs to the sewer main, are particularly susceptible to mid-line grease accumulation that a snake can't fully address.
Hydro-jetting was designed for exactly these conditions. The high-pressure water cuts through hardened deposits that no mechanical tool can match, and because it cleans the full pipe circumference rather than just boring a hole, it addresses the root cause of recurrence. For St. George homeowners and businesses, establishing a hydro-jetting maintenance schedule is one of the most cost-effective plumbing investments available.
Transparent from Start to Finish
How Our Service Works
Camera Inspection and Assessment
We insert a waterproof camera into your drain line to identify the exact location, nature, and extent of the blockage. This tells us whether hydro-jetting is the right tool, where to position the nozzle, and whether the pipe has any damage that could be worsened by high pressure.
Pressure Setup and Safety Checks
Our technician selects the correct nozzle type and pressure setting for your pipe material and blockage type. We protect your property, confirm downstream cleanout access, and set up containment before introducing water pressure.
Hydro-Jetting
We advance the high-pressure hose through the line, working from the cleanout toward the blockage. The rear-facing jets propel the hose forward while the front jet cuts through debris. We make multiple passes until the pipe walls are scoured clean.
Post-Jetting Camera Verification
After jetting, we run the camera through the pipe a second time to confirm the line is fully clear and document the condition of the pipe walls. You receive a verbal summary and, on request, a recording of the post-jetting inspection.
Compare Your Options
Hydro-Jetting vs. Drain Snaking
Both methods clear blockages, but they achieve very different results. Here's how they compare for St. George homes dealing with hard water scale and grease accumulation.
Our recommendation: For recurring blockages, hard water scale, or grease-heavy lines, hydro-jetting delivers better long-term value despite the higher upfront cost. Snaking is appropriate for simple, isolated blockages with no history of recurrence.
The Marlin Difference
Why Southern Utah Trusts Marlin
46 Years Serving Southern Utah Drain Lines
Marlin Plumbing has been clearing St. George drains since 1978. We know the soil conditions, pipe ages, and mineral content that make Washington County drainage a unique challenge — and we've built our process around them.
IAPMO Certification and Licensed Technicians
Every technician who operates our hydro-jetting equipment is IAPMO-certified and licensed by the state of Utah. That means the work is done to code, insured, and performed by someone who understands how high pressure interacts with your specific pipe material.
Camera-First Approach
We never jet blind. Pre-jetting camera inspection ensures we're applying the right solution to the right problem and that the pipe can handle the pressure — protecting you from an expensive repair caused by an overzealous fix.
Commercial-Grade Equipment
We use professional-grade jetting units capable of sustained 4,000 PSI output — not the consumer-grade equipment some plumbers carry. That power difference is the reason our jetting restores full bore flow where other methods fall short.

What Our Customers Say
“We'd had three plumbers snake our kitchen drain in two years and it kept coming back. Marlin came out, ran a camera, hydro-jetted the line, and we haven't had an issue in 18 months. Should've called them first.”
— Renee M.
St. George, UT
“Our restaurant in Coral Canyon had a grease line that was a nightmare every summer. Marlin put us on a scheduled hydro-jetting program and we haven't had a backup since. Worth every penny.”
— Daniel T.

“Fast, professional, and thorough. They showed us the camera footage before and after — you could see the difference immediately. The drain in our Bloomington Hills home flows better than it has in years.”

Coral Canyon Restaurant Ends a 3-Year Grease Line Battle
The Problem
A full-service restaurant in Coral Canyon had battled a recurring grease-line blockage for three years, calling a plumber 4–6 times per year as the line would slow or back up into the prep kitchen. Previous plumbers had snaked the line each time, providing 6–8 weeks of relief before the problem returned.
Our Solution
Marlin ran a pre-jetting camera inspection that revealed a 40-foot section of the grease line had less than 30% of its original bore open — years of hardened grease layered over mineral scale. We used a grease-cutting nozzle at sustained high pressure to fully restore the pipe bore, confirmed with post-jetting camera footage, then set the restaurant on a bi-annual preventive jetting schedule.
The Result
In 18 months on the maintenance schedule, the restaurant has had zero emergency drain calls. The owner estimates savings of over $2,400 in emergency service fees and lost revenue from kitchen downtime, against a maintenance cost of $700 per year.

Got Questions?
Hydro-Jetting FAQ
Answers from our certified technicians — based on the questions St. George homeowners ask most.
A drain snake is a mechanical auger that punches through a clog or breaks it into smaller pieces. It clears a path but leaves residue on the pipe walls. Hydro-jetting uses water pressure up to 4,000 PSI to scour the entire pipe interior, removing grease, scale, and root tendrils from wall to wall. The result is a pipe restored to close to its original flow capacity, not just one with a hole poked through the blockage.
