Sewer backup: what to do first.
A main line blockage is different from a sink clog. All the plumbing in the building drains into one pipe, so when it stops, the lowest fixtures show it first. In most Garfield houses that is a cellar floor drain, a basement shower or a laundry standpipe.
Stop the water, close the lids on floor drains, and open a window if there is an odor. Do not try to snake the main yourself. A cable machine that is not controlled can break an old pipe or hurt your hands. According to the State Board of Examiners of Master Plumbers, sewer line work must be done by a licensed master plumber or someone working under one, so ask to see a license before you agree to a price.
Where the blockage hides.
| Symptom. | Likely location. | What we do. |
|---|---|---|
| Floor drain bubbles after flushing. | Main line between the house and the street. | Cable the cleanout toward the street. |
| Tub backs up when the washer drains. | Main line or building drain. | Open the cleanout and cable both directions. |
| Only one bathroom is slow. | Branch line. | Clear the branch and test the main. |
| Backup returns every few months. | Roots, belly or damaged pipe. | Camera inspection, then jetting or repair. |
| Wet spot on the lawn or sidewalk. | Broken or collapsed pipe. | Camera inspection and repair plan. |
The cleanout is the plumber's door.
A cleanout is a capped pipe that gives direct access to the sewer line. Most houses have one in the cellar near where the main leaves the foundation, and some have a second in the yard. If you can find it, we can usually clear the line without touching a fixture.
If your house has no cleanout, we install one. It costs less than repeated emergency calls, and it lets the next technician work faster. Tell us whether the main sits under a finished floor and we will plan the access with you.
Cleaning the main, step by step.
Open the line.
We remove the cleanout cap and let pressure and standing water settle.
Run the cable.
A larger machine with a cutting head works through the blockage toward the street.
Retrieve and flush.
We pull out what we can, flush the line and confirm water flows freely.
Inspect if needed.
A camera shows roots, breaks or a belly that can cause the next backup.
Floor drain bubbling?
Call now. A dispatcher will tell you which fixtures to avoid until a technician arrives.
Roots, grease and old pipe in Garfield.
Many Garfield lines were laid decades ago in clay, cast iron or pitch fiber. Roots find the joints of clay lines easily, and cast iron scales and narrows from the inside. Both leave a rough surface where paper and grease catch.
If you are on a corner lot near the Passaic River or along River Drive, ground movement and high water tables can shift old pipe. We note any offset on the camera so you know whether it is a maintenance item or a repair job.
Who owns the sewer line.
In most New Jersey towns the homeowner owns the lateral from the house to the connection at the street main, while the municipality owns the main itself. The exact point varies, so we advise you to ask Garfield public works or the building department where your property responsibility ends.
If the blockage is in the municipal main, we can often tell by whether the neighbors on your block have the same symptoms. In that case, you report it to the city instead of paying for repair on a pipe that is not yours.
What changes the cost of sewer line cleaning.
You hear the price before work starts. If the camera finds a break, repair is a separate quote.
Where to go next.
If a camera shows a crack or collapse, sewer line repair is the path. For routine buildup, hydro jetting cleans the pipe walls. We also serve Lodi and Wallington, where the same backup symptoms come up.
Questions homeowners ask us.
Yes. The emergency line is open 24/7. We tell you which fixtures to stop using and send a technician as soon as one is free.
Look in the cellar near where the main pipe leaves the foundation for a capped pipe at floor level. Some homes also have one in the yard.
Usually the homeowner owns the lateral to the street. Ask Garfield public works where your responsibility ends, since the point differs by property.
Often only with a sewer backup endorsement. Check your policy and photograph the damage before cleanup.
A line without problems needs no schedule. Lines with roots or grease may benefit from a yearly or twice yearly cleaning.
We advise against it. Large cable machines can break old pipes and cause injuries when they are not controlled.
