Payson UT Sewer Line Backups: 6 Causes & Fixes

Estimated Read Time: 11 minutes

A sewer line backup can shut your home down fast. If you are seeing slow drains, gurgling, or wastewater coming up in a tub, you may have a sewer line backup. In this guide, we break down the six most common causes and how to fix them the right way. When it is time to act, Eric’s Plumbing & Drain Cleaning offers camera inspections, hydro‑jetting, and trenchless repair to clear and restore your line without tearing up your yard.

H2: 1) Tree Root Intrusion Tree and shrub roots hunt for moisture. In Utah County, cottonwood, willow, and elm roots are common offenders near older clay or Orangeburg lines. Roots enter through tiny cracks or loose joints, creating a root mat that traps paper and grease and causes backups.

How to spot it

• Slow drains in multiple fixtures
• Gurgling after toilet flushes
• Roots seen on a camera inspection

How to fix it

1. Mechanically cut roots with a flex‑shaft tool. The chain head with carbide tips scrubs roots and scale from inside the pipe.
2. Hydro‑jet to flush remaining root hairs and debris. We use over 4,000 PSI water pressure to scour the line.
3. Restore the pipe. If joints leak or the host pipe is damaged, line the pipe with a cured‑in‑place liner or replace with pipe bursting to prevent roots from returning.

Future prevention

• Avoid planting thirsty trees over the lateral
• Schedule annual sewer camera inspections to catch early intrusion

"Hunter did a drain cleaning and was able to fix the sewer line a week later that connected to the city line. He was quick and also very clear in explaining the issue..."

H2: 2) Grease, Wipes, and Debris Buildup Kitchen grease, flushable wipes, feminine products, and excess paper do not break down fast. Over time they form a sticky dam that collects more debris until flow is choked off.

How to spot it

• Backups often start after heavy kitchen use or guests
• Camera shows sludge, rags, or wipes hanging in the line

How to fix it

1. Hydro‑jetting. A jetter head delivers focused streams to emulsify grease and shred soft obstructions. Done correctly, it restores the pipe wall to bare material.
2. Flex‑shaft descaling if mineral scale has narrowed the pipe. Descaling removes hard buildup and gives the jetter a clean path.
3. Evaluate pipe integrity on camera. If joints leak or pipe is cracked, consider lining to keep new debris from snagging.

Future prevention

• Never pour cooking oil in drains; collect and trash it
• Only flush human waste and toilet paper
• Use strainers on kitchen sinks

"I had a main sewer line clog over the weekend... Eric's had a technician at my house in 40 minutes... cleared the blockage in under 2 hours... took a video of the inside of our drain so I could see what was going on."

H2: 3) Offsets, Cracks, and Collapsed Sections Aging clay, cast iron, or Orangeburg lines can crack or shift. Soil movement and freeze‑thaw cycles in Utah clay expand and contract around the pipe, leading to misaligned joints, cracks, or collapses. Paper and solids then snag, which triggers recurring backups.

How to spot it

• Frequent backups in the same section
• Camera reveals offsets, fractures, or a deformed oval shape
• Locator marks a precise problem area in your yard or driveway

How to fix it

1. Start with a full camera inspection and electronic locating. We record video and pinpoint depth and position to plan the least invasive repair.
2. If the host pipe is intact enough, install a trenchless CIPP liner. Our UV‑cured Bluelight system allows inspection before curing and cures up to 4 times faster than traditional methods.
3. If the pipe is severely broken or crushed, use pipe bursting. We break the old pipe while pulling a new high‑density line into place with only small access pits.

Future prevention

• Avoid heavy vehicle traffic over the known sewer path
• Keep up with annual inspections to catch movement early

"Great experience having the main line replaced."

H2: 4) Bellies and Low Spots A belly is a sag where the pipe has settled. Wastewater slows in the dip, leaving solids behind. Over time, the belly becomes a sludge trap that causes slow drains and random backups.

How to spot it

• Camera shows standing water in the line
• Backups are sporadic and worse after heavy water use

How to fix it

1. Clear the line first with hydro‑jetting to restore flow and visibility.
2. Evaluate if the belly is short and shallow. Short bellies can sometimes be managed with maintenance and a sectional liner if the host pipe is otherwise sound.
3. If the belly is long or severe, the best fix is to regrade the line. We may recommend pipe bursting with proper slope or a targeted excavation to correct the pitch.

Important limitation

• Not every belly is a good candidate for lining. Severe bellies and badly out‑of‑round pipes should be replaced for reliable flow.

"Quick emergency response to clogged sewer line and flooding basement. Will definitely call for any future plumbing issues."

H2: 5) Foreign Objects and Construction Debris Children’s toys, dropped shop rags, and construction material can lodge in the line. Even a small obstruction becomes a lint catcher that traps everything behind it.

How to spot it

• Backups start after a remodel or a known incident
• Camera shows a defined object or edge inside the pipe

How to fix it

1. Attempt retrieval with specialty heads, grabbers, or jetting nozzles.
2. If the object is stuck in a damaged section, line or replace that section to seal off edges that snag flow.
3. Document with before and after video so you can see the resolution.

Future prevention

• Cap open drains during remodeling
• Keep wipes, rags, and shop towels out of drains

"I just had to get a video of the sewer lateral and Eric's was great... best price... in and out in about an hour... walked me through the video and then got it to me within 10 minutes."

H2: 6) Poor Venting and Low‑Flow Fixtures Plumbing systems need air to move water. If vents are blocked or undersized, fixtures can gurgle and drain slowly, which mimics a sewer backup. Ultra low‑flow fixtures can also underperform in older piping with scale.

How to spot it

• Gurgling at a sink or tub when other fixtures run
• Intermittent slow drains with no mainline obstruction on camera

How to fix it

1. Camera the mainline to rule out obstructions.
2. Inspect and clear roof vents. A quick vent auger or cleaning can restore air supply.
3. Descale older cast iron to increase internal diameter, which improves low‑flow performance.
4. If the main is clear and vents are good, evaluate fixture traps and branch lines.

Future prevention

• Keep roof vents free of leaves and nests
• Pair low‑flow fixtures with clean, properly vented piping

"Eric and company took a high quality video of our sewer line, identified its problems, and gave us expert advice."

H2: How We Diagnose Sewer Line Backups the Right Way Backups have different root causes. Guessing leads to repeat calls. Our process removes guesswork and proves results.

What we do on every job

1. Perform a full video sewer camera inspection. We record everything so you can see the problem and the fix.
2. Pinpoint the issue with a locator. We mark depth and location to avoid unnecessary digging.
3. Clear the line using the right method. Options include auger, hydro‑jetting at 4,000+ PSI, and flex‑shaft descaling for hard deposits.
4. Verify flow and condition on camera. You see before and after footage for full transparency.
5. Recommend the most durable repair. If the host pipe is viable, we install a UV‑cured Bluelight liner that is made to last 50 years. If not, we use pipe bursting or targeted replacement.

Hard facts you can count on

• Our UV‑cured Bluelight liners cure up to 4 times faster and allow us to inspect the liner before curing starts.
• We back repairs with a 100% satisfaction guarantee and a one‑year repair warranty. Cleaning services include a 30‑day clear‑drain guarantee.

H2: Trenchless Repairs: Fast, Durable, and Yard‑Friendly Traditional excavation tears up landscaping, driveways, and sidewalks. Trenchless methods fix the pipe using small access points, which reduces cost and disruption.

Two proven options

1. Pipe lining with CIPP. We insert a resin‑coated liner, expand it against the host pipe, then cure it with our Bluelight UV system. Result: a seamless, jointless pipe designed for a 50‑year service life.
2. Pipe bursting. For severely damaged lines, we fracture the old pipe while pulling in a new high‑density pipe of the same or larger diameter. Only small pits are needed.

Why homeowners choose trenchless

• Minimal disruption to your yard and hardscapes
• Faster completion and less restoration cost
• Documented results with before and after video

"Eric's Plumbing is doing business right and I highly recommend calling them first."

H2: DIY vs Pro: When to Call for Help There are safe homeowner steps, and there are red flags that need a licensed pro.

Safe first steps

1. Stop using water to prevent flooding.
2. Check for a visible cleanout cap and carefully remove it to relieve pressure if sewage is backing up indoors.
3. Try a plunger on a single clogged fixture. Do not use chemical drain cleaners, which can damage piping and are hazardous.

Call a pro if

• Multiple fixtures are backing up, or sewage is visible
• You hear gurgling throughout the home
• You suspect roots, a collapse, or a belly
• You need hydro‑jetting, flex‑shaft descaling, or trenchless repair

Frequently Asked Questions

How do I know if my sewer backup is in the main line or just a branch?

If multiple fixtures on the lowest level back up at once, it is likely a main line issue. A camera inspection confirms location and cause so you can target the fix.

Can hydro‑jetting damage my pipes?

When performed by trained techs with the right nozzles and pressure, hydro‑jetting is safe for most materials. It uses over 4,000 PSI to clear debris and is followed by a camera check.

How long does a trenchless liner last?

A properly installed CIPP liner is designed for a 50‑year service life. Our UV‑cured Bluelight system speeds cure and lets us verify placement before curing.

Is every sewer line a candidate for lining?

No. Severe bellies, major breaks, large offsets, or badly out‑of‑round pipes often require pipe bursting or targeted replacement. We confirm with a camera and locator.

Do you warranty your sewer repairs?

Yes. We offer a 100% satisfaction guarantee and a one‑year repair warranty. Hydro‑jet and mainline cleanings include a 30‑day clear‑drain guarantee.
