Sewage coming back up through a floor drain or tub is a health problem as well as a plumbing one, so treat it as urgent. Dispatch for sewer line cleaning in Newark, DE runs 24/7, and until the plumber arrives you should stop using water, keep people and pets away from the affected room, and leave the dishwasher and washing machine off.
This page is about cleaning a blocked lateral or main line. If a camera shows a cracked, collapsed or sagging pipe, that moves into sewer line repair.
Sewage backing up: what to do in the first few minutes
- Stop all water useEvery flush, shower, dishwasher cycle and load of laundry sends more water toward a line that has nowhere to put it.
- Keep people out of the areaSewage can carry bacteria, so children and pets should stay out of the wet room.
- Do not run the dishwasher or washing machineBoth discharge a lot of water at once and push the backup into the lowest drain in the house.
- Look at the other fixturesNote whether the basement floor drain, the toilets and the tub are all affected. That tells the plumber the blockage is in the main line or lateral.
- Protect what you canLift rugs and cardboard off the floor, and keep electrical devices out of standing water.
- Call us and tell the dispatcher everything you sawA licensed plumber can then arrive with the right cable and a plan for the cleanout.
Night and weekend backups follow the same pattern, and same-day appointments are offered when the schedule allows.
Who clears which pipe in Newark
The City of Newark takes care of more than 100 miles of sanitary sewer main under the streets. The pipe from your house to that main is called the lateral. According to the City's Sewer Care Guide, a blockage in the lateral is for the owner to arrange to have cleared, while the City clears blockages in its own main.
The City's Water Resources team is available around the clock for sewer backups. Its crew generally checks the main under the street first, and if the main is clear, the next call is to a plumber for your lateral.
The municipal code (Sec. 25-2) adds a wrinkle for roots. A property-line cleanout changes who handles root clearing between the line and the main, so ask the plumber to locate yours before assuming the whole lateral is on your tab. If you live in Bear, our Bear plumbing page applies. Bear is outside the City, so County sewer rules apply where a home is connected.
| What you see | Likely location | First move |
|---|---|---|
| Only one fixture is slow | Branch line in the house | Fixture cable, see the drain page |
| All lower drains back up, upstairs works | Lateral or main | Call the City and a plumber |
| Neighbors report the same problem | City main | Call the City's Water Resources team |
| Backup returns every few months | Roots, grease or a low spot in the lateral | Clean, then run a camera |
A single slow fixture is a job for fixture drain work. This page is for the pipe that serves the whole house.
How a sewer lateral gets cleaned
The plumber starts at the cleanout. If your home has one outside near the foundation, or at the property line, the cable goes in there. If it does not, access may come through a basement cleanout, a roof vent, or a pulled toilet. A drum machine feeds a heavy cable with a cutting head through the line until it reaches the blockage.
What the cable meets tells the story. Soft resistance with grease on the cable points to buildup. A sudden stop followed by grinding and then root fibers on the head points to roots. A hard stop that does not give can mean a collapsed pipe or an offset joint, and that is when a camera belongs in the conversation.
For heavy grease or repeat trouble, a high-pressure jet cleans the pipe wall more fully than a cable does. A cable restores flow, and a jet restores capacity.

Cleaning a sewer line before it backs up
Not every cleaning is an emergency. Some owners have a lateral cleaned after a close call, before a rental turnover, or after buying a home with no sewer history. A planned cleaning is less disruptive than a Saturday-night backup, and it lets the plumber see what the line looks like.
There is no set cleaning schedule. Roots, grease habits, pipe material and slope all matter. A better rule is to clean when symptoms appear, run a camera when they repeat, and repair when the camera shows damage.
Backflow prevention and insurance
The City's guide suggests considering a backflow prevention device that stops sewage from coming back into the house. A device does not clear a clog. It stops backed-up water from reaching your lowest fixtures, and a plumber can tell you whether your basement layout allows one.
The same guide notes that many homeowner policies exclude sewage backup. Ask your agent whether sewer backup coverage is available, and do it before an incident, because adding coverage after a loss is too late.
What affects the price of sewer line cleaning
Sewage damage is a separate matter from the cleaning bill. Most policies cover sudden and accidental loss, but many leave out sewage backup unless you added a rider, so read your declarations page and your endorsements. Call us for your actual number, and a clear price comes before the cable goes in.
Sewer cleaning questions from Newark homeowners
Sewer backup calls are taken at any hour, Sunday nights and holidays included. The City's Water Resources team also works around the clock, so you can contact both. A plumber can clear the lateral while the City checks its main.
Call both. The City's guide says its crew checks the main, and that if the main is clear you need a plumber for the lateral. Doing both at once avoids a wait if the problem turns out to be on your side.
Often not. The City's sewer guide notes that many homeowner policies exclude sewage backup. Check your declarations page and ask your agent whether a sewer or water backup endorsement is included.
The City asks residents to keep fats, oils, grease, rags, disposable diapers and sanitary napkins out of drains. The EPA lists wipes, including some marked flushable, among items that cause blockages.
For now, yes. If it returns, a camera inspection shows whether roots, a low spot or a damaged joint is feeding the clog.
You can rent a cable, but a lateral is long, and a cable can jam or scrape an old pipe. A backup can also put sewage in the home. If you hire out, you can verify any plumber's license at the state lookup at delpros.delaware.gov.
