Sewage coming up in a basement floor drain or the lowest tub is the main sewer line telling you it is full, and our 24/7 dispatch line in Braintree, MA is built for that call. While you wait, stop all water use in the house, because every flush and load of laundry adds to the pile in the pipe.
Sewer line cleaning means clearing the single large pipe, the lateral, that carries all the house's waste out to the municipal sewer. Roots, grease, wipes, a sagging section and a crushed joint are the usual causes. The smaller sink and tub pipes inside the house are a different job, covered under drain cleaning, and the water-pressure method is explained on our hydro jetting page.
Sewage backing up into the house tonight
Wastewater carries bacteria, so the first job is keeping people out of it while keeping more from arriving.
- Do not use any plumbing fixture, including the toilets and washing machine.
- Keep children, pets and bare feet out of the wet area.
- Open a window if there is a strong odor and keep the area ventilated.
- Call (617) 752-0573. We take overnight and weekend backups the same as daytime ones.
Signs the main line, not a single drain, is the problem
A main line blockage has a recognizable pattern. It starts at the lowest point in the house and works upward.
Basement drain or tub burps.
A floor drain gurgles when a toilet flushes upstairs. Air and water are being forced back up the nearest open pipe.
Several fixtures slow at once.
A shower, a toilet and a laundry sink all drain badly together. A single trap cannot cause that.
Toilet flush raises the tub.
Water leaves one fixture and appears in another because both share the blocked section.
Sewer smell in the yard.
A wet patch or odor near the cleanout or along the lateral can mean the pipe is breaking and leaking out.
Repeated clogs that clear and return.
Roots or a belly in the pipe refill quickly after each cable pass.
Lush stripe of grass.
A strip of greener lawn along the line can come from a slow leak feeding the soil.
Sewage in the basement?
Stop all water use and call (617) 752-0573. We take main line backups day and night.
Where the line runs and who looks after which part
Braintree is a sewered town, with the Water and Sewer Department operating the system and flows going on to the MWRA. Town rules make the property owner responsible for the lateral from the house to the property line. The section in the public way is the Town's.
The wording in the Town regulations is not perfectly consistent, so confirm the boundary with the Braintree Water and Sewer Department before you decide who pays for work out near the street. It matters here because a blockage at the property line is a different conversation from one inside your yard.
How we cable a main line from the cleanout
The job begins at the cleanout, the capped pipe that gives direct access to the lateral. Some houses have one in the basement, near the foundation wall or in the yard.
Find and open the cleanout.
We unscrew the cap slowly, since a full line can push sewage out when released, and we set up containment first.
Feed the cable.
A sectional machine with a cutting head turns as it advances. We watch the resistance and note the distance at every change.
Clear and retrieve.
Roots, paper and grease come back on the cutter and are bagged. We repeat until the cable runs clean to the street connection.
Flow test and recommend.
We run water through the house and recommend a camera look if roots or a belly were found. Cutting alone does not fix a damaged pipe.
What the cable brings back and what it means
| Debris on the cutter | Likely cause | What we recommend. |
|---|---|---|
| Fine hair roots. | Roots entering at a joint. | Clear now and camera the line to find the joint. |
| Grease and soap paste. | Years of kitchen waste coating the pipe. | Consider jetting to clean the full wall. |
| Wipes and paper mass. | Flushed wipes and toilet paper lodging at a bend. | Stop flushing wipes and recheck in a few weeks. |
| Dirt or sand, no waste. | Pipe cracked or collapsed with soil entering. | Camera and likely sewer line repair |
The last row is the one we hope not to see. Soil on a cutter means the pipe is no longer a closed tube.
No cleanout in the basement
Many older houses never got a proper cleanout. In that case we may go in through a toilet, which means pulling it and resetting it with a new wax ring, or through a roof vent. Both work but cost more time than a cleanout.
If yours is missing, installing one is usually worthwhile. It turns every future backup into a short visit instead of a toilet removal.
What affects the price of cleaning a main sewer line
Main line work depends on what the pipe contains and how we reach it, not on a flat menu.
A sudden sewage backup may be covered by a water backup endorsement. Routine line cleaning usually is not. Photograph the damage, keep receipts and call (617) 752-0573 for a clear price before work starts.
Main line questions, answered
Yes. Our 24/7 dispatch line takes sewage backups at any hour. Stop using water, keep people out of the wet area and call (617) 752-0573.
Town regulations place the lateral from your house to the property line with the owner, and the part in the public way with the Town. The wording is not fully consistent, so confirm the boundary with the Braintree Water and Sewer Department.
There is no calendar that fits every house. A line with roots or a belly may need attention regularly, while a healthy one may never. A camera look tells us which you have.
Cutting removes them for a time. They return unless the joint they enter is repaired, which is where sewer inspection helps decide the next step.
Often only if you carry a water backup endorsement. Ask your insurer before cleanup and photograph the area.
Yes. See our Randolph page for the area we cover from Braintree.
