The main line is backing up: what to do in this order
A main line backup is time-sensitive because the water level rises as long as anyone uses the house plumbing.
- Stop using toilets, sinks, showers, dishwashers and washing machines straight away.
- Look at the lowest drain. If it is wet or bubbling, the main is blocked below the house.
- Find the exterior or basement cleanout and tell the dispatcher where it is, but do not open it.
- Lift valuables from the basement floor, and keep the area clear for the plumber.
- Call and report whether neighbors are affected, since a shared blockage may be in the street pipe.
Where the main line begins and ends
The main sewer line starts where the branch drains from your bathrooms, kitchen and laundry join. It runs out of the house, usually under the slab or through the basement wall, and carries on to the town connection or the septic tank.
Anything that blocks that single pipe affects the whole house. That is why a slow tub, a gurgling toilet and a wet floor drain on the same day all point to one cause.
Only the part of the pipe on your property is yours to maintain. A blockage in the street main belongs to the town, which is why asking neighbors matters.
Cleaning by cable, by jet, or not at all
A main line needs a bigger machine than a sink drain. The choice between cable and jet depends on what the sewer camera inspection shows.
| What is in the line | Method | Notes |
|---|---|---|
| Paper and waste plug | Machine cable with a retriever head | Fast and usually enough. |
| Heavy roots | Cable with a cutting head, then a jet | Roots return unless the joint is sealed. |
| Grease and scale | Hydro jet | Leaves a cleaner wall and a longer interval. |
| Foreign object | Retriever or camera-guided tool | May need the toilet pulled. |
| Collapsed pipe | Cleaning cannot fix it | Camera shows it and repair is planned. |
Why the main clogs in spring and after storms
Westborough holds the headwaters of the Sudbury and Assabet rivers, along with Lake Chauncy, Sandra Pond and Hocomonco Pond. Wet seasons raise groundwater, and soil water can press on older pipe joints.
If a main line clog appears during or after heavy rain, tell the plumber. The camera can look for water entering through joints, which changes the repair plan from cleaning to sealing.
Signs the main line needs attention before it fails
A main line gives warnings. Learn these, and you can book a visit before it becomes an emergency.
- More than one fixture drains slowly at the same time.
- A toilet bubbles or a floor drain gurgles when you run the washing machine.
- A sewage smell appears in the basement or at the cleanout.
- Green or unusually lush patches appear in the yard along the line's path.
- Backups return within months of the last cleaning.
Cleanouts: the small fitting that saves a lot of work
A cleanout is a capped access pipe that lets a machine enter the main line directly. Many older homes have none, or have one buried or painted over.
Without a cleanout, the plumber pulls a toilet or enters through a roof vent, which takes longer. Adding a cleanout during a repair is a modest extra that makes every later visit cheaper, and it is worth asking about. Related repair work is described under sewer line repair.
Property managers and Grafton-side calls
Multi-unit buildings share a main line, and one tenant's clog backs up into the lowest unit. Property managers should keep a record of cleanings and camera footage to see patterns.
Dispatch from Westborough reaches Grafton's villages, North Grafton, Grafton and South Grafton, as described on the Grafton emergency plumbing page. Give the village name and ZIP when you call.
What changes the cost of cleaning a main sewer
You hear a clear price before work starts, and these are the factors.
Cleaning a clogged line is usually a maintenance cost that insurance does not cover. Water damage from a sudden backup may be covered if you have a backup endorsement.
Call and describe the symptoms, and the dispatcher will give you a price range first.
When every drain in the house slows at once, the main line is the place to look. Call early, before the basement floor drain starts to rise.
Code and standards note. Cleaning a main line does not alter the piping, but any repair uncovered by the cleaning falls under 248 CMR 10.00. Call 811 Dig Safe before any digging near a buried line.
Sewer Line Cleaning questions from Westborough homeowners
Yes. Dispatch is open 24/7 and a licensed plumber is sent to clear the main and camera it. If sewage is rising in the house, say so first so your call is placed ahead of routine requests.
If neighbors on the same street have no problems, the blockage is probably on your property. If several homes back up, report it to the town. The plumber can tell by whether the cleanout is full.
Only as needed. A sound pipe may never need a second cleaning. A line with roots or grease may need one every one to three years, and the camera tells you which.
It is better not to. A full line can discharge forcefully and flood the area. Let the plumber open it with a collection setup ready.
A properly sized cable or jet used on a sound pipe does not. Old thin iron and clay need lighter tools, which is why the plumber asks the age of the home.
Then it is not a cleaning problem. The camera will usually show a broken joint or a low spot, and a repair is the lasting answer.
