Sewer Problems Escalate Fast — Act Early
Sewer problems can escalate quickly from inconvenient to catastrophic. A slow drain becomes a full backup. A hairline crack becomes a collapsed section. Marlin Plumbing provides comprehensive sewer services — from routine cleaning and root removal to emergency plumbing repairs and full line replacement.
Washington County's clay and iron-rich soils, combined with mature tree roots in older neighborhoods, make sewer line issues common in St. George. Our sewer camera inspection technology lets us diagnose the exact problem before recommending a solution — which means you're not paying for excavation before we know what we're dealing with. We've seen everything from root-choked lines in 1960s Bloomington homes to bellied pipe under shifting red clay in newer Toquerville developments.
For homes dealing with repeated sewer backups, the underlying cause is almost always structural — not something a snake or chemical treatment can permanently fix. Tree roots grow back. Bellied sections collect debris again. Cracked pipe walls let in more soil. When cleaning alone isn't holding, we'll run a camera, show you exactly what's happening, and lay out your options: spot repair, pipe lining, or full replacement. If your drain services keep bringing temporary relief that doesn't last, it's time to look deeper.

Know the Warning Signs
Signs You Need Sewer Services
Catching these early prevents a small issue from becoming a costly emergency.
When every drain runs slow — not just one — the problem is in the main sewer line connecting your home to the city system.
Sewer gas odors indoors indicate a venting problem or cracked pipe. Odors in the yard may point to a sewer line leak underground.
A soft, wet, or unusually green patch in your yard above the sewer line is a strong indicator of an active leak or collapsed section.
Sewage appearing in floor drains or lower-level fixtures during heavy use means the main line is blocked and backing up.
Local Expertise
How St. George's Red Rock Soil Affects Your Sewer Line
Southern Utah's distinctive red soil is beautiful but tough on underground pipes. The clay-heavy composition is expansive — it swells when wet and shrinks when dry. In a region where monsoon rains can dump an inch of water in an hour followed by weeks of bone-dry conditions, that expansion-contraction cycle stresses rigid sewer pipe at every joint. Over decades, the movement opens gaps that tree roots exploit.
The problem is compounded in older neighborhoods like Bloomington, Sunset, and areas near the Virgin River where the soil profile is particularly aggressive. Homes built in the 1960s–1980s often have cast iron or orangeburg sewer lines that were never designed to handle this kind of ground movement for 40+ years. We see a disproportionate number of sewer failures in these areas compared to newer subdivisions built on more stable, pre-engineered fill.
St. George's construction boom has added another dimension. Fast-growing neighborhoods in Washington Fields and areas south of the city are built on compacted desert soil that can settle unevenly as it consolidates over the first 5–10 years. This settling can create bellies in sewer lines — low spots where waste pools and eventually causes blockages. If your home is relatively new and you're already dealing with recurring slow drains, settling may be the cause.

Trenchless Sewer Repair vs. Traditional Excavation
Both methods solve sewer line problems permanently. The right choice depends on your pipe's condition and your property layout.
Our recommendation: For St. George homes with cracked but intact sewer lines, trenchless repair saves time and landscaping costs. For collapsed lines, orangeburg pipe, or severe bellies — which are common in older Bloomington and Santa Clara neighborhoods — traditional excavation and PVC replacement is the more reliable long-term solution.

What Our Customers Say
“Sewer backed up into our laundry room. Marlin came out the same day, ran a camera to find the problem — tree roots had cracked the line about 20 feet from the house. They replaced the damaged section and even helped coordinate the landscaping repair. Incredible service from start to finish.”
— Karen S.
St. George, UT
“Had a recurring backup in our downstairs bathroom about every 6 months. Two other companies just kept snaking it. Marlin ran a camera and found the pipe had bellied about 30 feet out — waste was pooling and creating blockages. They replaced the 8-foot section and it's been perfect for over a year now.”
— Ron M.
Hurricane, UT
“Our sewer line was destroyed by cottonwood tree roots. Marlin gave us two options — dig and replace or trenchless lining. They explained the pros and cons of each honestly. We went with replacement since the pipe was orangeburg and wouldn't support a liner. They finished in two days and the yard was cleaned up better than I expected.”
— Linda and Paul F.
Toquerville, UT

Emergency Sewer Replacement: Orangeburg Collapse in La Verkin
The Problem
A homeowner experienced a sudden full sewer backup on a Saturday morning. Two bathrooms and the kitchen were backing up simultaneously. A previous plumber had snaked the line 6 months earlier for a similar issue, but the backup returned worse than before.
Our Solution
We ran a sewer camera and discovered the original 1968 orangeburg pipe had collapsed in two locations — one about 25 feet from the house and another near the city connection. The pipe was too deteriorated for lining. We excavated and replaced the full 60-foot run with schedule 40 PVC, installed two new cleanouts for future access, and restored the yard grade.
The Result
The homeowner went from twice-yearly backups to zero issues. The new PVC line has been flowing clean for over two years. The added cleanouts make future maintenance straightforward if it's ever needed.

Sewer Services FAQ
Answers from our certified technicians — based on the questions St. George homeowners ask most.
Multiple slow drains, sewage odors indoors or in the yard, gurgling sounds from toilets, wet or sunken spots in the yard, and sewage backing up through floor drains or tubs. If more than one fixture is affected, the problem is almost always in the main sewer line.
