Sewer backup: what to do first
A backup tells you the lateral, the pipe between your foundation and the district main, cannot carry what you send it. Every minute of water use adds to what is already on the floor. The first job is to stop adding to it.
- Stop using sinks, tubs, the dishwasher and the washing machine. Do not flush.
- Keep children and pets out of any room with standing sewage, and do not wade through it barefoot.
- If water has reached outlets or a furnace, leave the breaker alone unless you can reach it while standing dry.
- Note the lowest fixture that overflowed. A basement floor drain or tub usually fails first because it sits closest to the pipe.
- Do not pour drain chemicals into a backed-up line. They sit in the pipe and can burn whoever opens it next.
Which part of the sewer belongs to you in North Davis Sewer District
Clearfield homes connect to North Davis Sewer District. Under the district's 2025 ordinances, a building sewer, including its connection to the main, is owned and maintained by the connected property owner. The district owns the collection mains in the street.
That split decides who calls whom. If the blockage or break sits between your house and the connection, repair is the owner's job. If a neighbor's drains are also backing up, the main may be involved, and the district takes reports on its own lines.
A camera run answers the question with a picture instead of a guess. The footage shows whether the damage is on your side of the connection. The ordinance also lets the district require a backwater valve on some connections, paid for and maintained by the owner, so ask about one before you close up a new lateral.

Signs the line under your yard is failing
Lateral damage rarely arrives as a surprise flood. It usually gives weeks of small warnings before the day everything backs up at once.
What you hear and see inside
Gurgling in a toilet when the washing machine drains is the classic one, because air is being pushed back through traps. Toilets that bubble after a shower, a basement floor drain that weeps, and slow drains on every fixture at once all point downstream of the branch lines.
What shows up outside
A sewage smell near the lawn, a soft or sunken strip running from the house toward the street, and grass that is greener and thicker over one narrow line can mean waste is leaking from the pipe. Wet ground over the lateral during a dry week deserves a camera.
How the plumber finds the break
The plumber feeds a waterproof camera head on a flexible push cable through the cleanout. Roots, offset joints, cracks, standing water in a low spot and scale on old iron all show on the monitor. A transmitter in the camera head lets a handheld locator mark the surface above any defect and read its depth.
Cleaning usually comes first, since a camera cannot see through a clog. If the line is packed with roots or grease, the plumber clears it, then runs the camera again to see what the roots were feeding on. You can read more about the inspection itself on our sewer camera inspection page.
A camera cannot see a leak inside a wall or a failed vent stack. It does show material, condition and location, which is what a repair plan needs.
What the plumbing code and permit office mean for a sewer repair
Clearfield City's 2026 design criteria list the 2024 International Plumbing Code as the adopted plumbing code, effective July 1, 2026. Replacing a section of sewer line counts as replacement plumbing line work, which the city's permit guidance puts on the permit side of the line, while fixture swaps stay off it.
Ask how the permit will be handled before the trench opens. An open excavation waiting on paperwork is the delay you can prevent with one question.

Call (801) 207-7520Repair options, matched to what the camera shows
No single fix suits every lateral. The right one depends on what failed and how much pipe around it is still sound.
| What the camera shows | Usual repair | When it makes sense |
|---|---|---|
| Roots in joints | Cleaning, then spot repair | Pipe is otherwise round and sound |
| One cracked or offset joint | Spot dig and section swap | Damage is short and reachable |
| Belly holding water | Replace that section | Sag keeps fouling the line |
| Long run of worn pipe | Pipe lining | No collapse, and the pipe can be cleaned |
| Collapsed or crushed pipe | Dig and replace | Nothing remains to line |
| Scaled, thinning cast iron | Replace or line | Walls are failing, not just rough |
Lining and digging can be combined on one lateral, for example lining the straight run and replacing a collapsed elbow.
Cast iron, clay and what your home's age suggests
Census figures put Clearfield's median home at 1989, but 987 homes date from before 1950 and about 39 percent were built before 1980. Build year only hints at the sewer material. Older neighborhoods can have cast iron or clay tile, newer ones usually plastic, and a remodel may have swapped part of the line. The camera settles it.
Old cast iron rusts and scales from the inside, which narrows the bore and gives roots and grease a rough surface to catch on. Clay tile fails at its joints. Both can often be cleaned and then either repaired in sections or lined.
Lining, honestly
A liner is a resin-saturated sleeve pulled into the cleaned old pipe and cured so it hardens into a new pipe inside the old one. It avoids a trench across the yard. It shrinks the bore slightly, it cannot straighten a belly, and it needs a pipe that is still in one piece. Side connections have to be reopened afterward, which a good crew checks with the camera.
Digging, honestly
A trench costs you landscaping, a driveway edge or a sidewalk section, but you end up with brand-new pipe at a known slope. Clearfield's design criteria list a frost line of 30 inches, so in a hard freeze the crew is breaking through frozen soil and the schedule may stretch. Plan around the weather, not the calendar. We run the same camera-first process for homes in Roy and Layton.
Cleaning the main versus repairing it
A blocked main with sound pipe needs cleaning, not repair. Our sewer line cleaning crews use cable machines or a water jet depending on what is in the line, and grease is the usual jet job, and our hydro jetting page explains how that works.
Cleaning treats the blockage. It does not treat the reason the blockage formed. When the same line backs up again within a few months, or a camera finds the same root mass in the same joint, the pipe is the problem and cleaning becomes a stopgap.
North Davis Sewer District says fats, oils and grease plug sewer lines more than anything else, and that wipes sold as flushable should never be flushed. Both are cheap to stop and expensive to dig out.
Permits, 811 and the dig
Clearfield City lists new and replacement plumbing lines as permit work, while fixture swaps do not need one. Permit rules vary by project, so ask the Clearfield City building department what applies to yours before any pipe is replaced.
Anyone who digs in Utah must notify Blue Stakes of Utah at 811 at least three business days ahead, and the person doing the digging makes the request. That wait is built into any planned excavation. It does not apply to an emergency camera visit, which needs no dig.
What decides the price of a sewer line repair
A fair price comes after the camera, not before it. Here is what moves the number.
- Length of pipe involved
- A one-joint repair and a replaced run from the house to the connection are different jobs.
- Depth and access
- A shallow lateral under lawn is easier than one under a driveway, patio, tree or retaining wall.
- Method
- Spot dig, trench replacement and lining use different crews, materials and equipment.
- Pipe condition and material
- Cast iron, clay and plastic fail in different ways, and a worse pipe means more to replace.
- Permits and restoration
- Permit work, inspections and repairing what was disturbed all add time.
Homeowner policies usually cover sudden and accidental damage and exclude wear, age and root growth. Sewer backup coverage is often a separate endorsement, so read your policy or ask your agent before assuming either way.
You get a clear price before work starts. Call (801) 207-7520 and we will send a licensed plumber, same day when the schedule allows.
When it is not a sewer line repair
One slow kitchen sink with a healthy shower and toilet is a branch clog, and a plumber will clear it without touching the lateral. See drain cleaning for that.
We do not treat septic systems. Clearfield sits inside the North Davis Sewer District, but a property on a tank needs a septic specialist. And if the whole street is backing up, the blockage may be in the district main, in which case the district is the call.
Sewer line questions we hear from Clearfield homeowners
Do you handle sewer line repair emergencies at night or on weekends in Clearfield?
Yes. The dispatch line runs 24/7, including nights, weekends and holidays. A licensed plumber is sent as soon as scheduling allows. We do not promise a set arrival time, because it depends on call volume and where crews are. Tell us which fixtures are backing up.
Who is responsible for the sewer line from my house to the street?
You are, up to the main. North Davis Sewer District's ordinances place ownership and upkeep of the building sewer, connection included, on the connected property owner. The district owns the collection main in the street. A camera run shows which side of the connection holds the damage.
Should I call North Davis Sewer District or a plumber when sewage backs up?
Start with a plumber if only your house is affected, since the lateral is usually yours. If neighbors are also backed up or a manhole is overflowing, report it to the district, because those are its lines. Calling both is fine.
How do I know if tree roots caused my backup?
Slow drains over several months, repeat backups, and mature trees near the lateral all point to roots. The camera is the proof. Roots show as pale fibrous masses entering at joints. Catching them early often means a spot repair rather than a replaced line.
Can lining fix any damaged sewer pipe?
No. A liner needs a pipe that can be cleaned and still holds its shape. A collapsed section, a belly holding standing water or a badly offset joint usually needs a dig. The footage decides.
Does homeowner insurance pay for sewer line repair?
It depends on the policy and the cause. Sudden and accidental damage is more likely to be covered than wear, age or roots, and sewer backup is frequently a separate endorsement. Ask your agent before work begins. Keep the camera footage, since adjusters often ask for it.
Do you work on septic systems?
No. We repair and clean laterals connected to the public system, which in Clearfield means North Davis Sewer District. A property on a septic tank needs a septic contractor. We can still look at the house plumbing leading to the tank.
