What is the Main Sewer Line? The main sewer line is exactly what you think it is. It's the plumbing line that channels all of the waste from toilets, tubs, and sinks out of your home, toward the main sewer under the street in front of your home.
It can typically be found in the basement, crawl space or garage. You will want to search for a pipe that is approximately four inches in diameter with a screw cap on the top that has a notch or square knob at the top. Note that some homes have an indoor sewer cleanout point, while others may be located outdoors.
What is a Main Line? To put it simply, your main line is your sewer line. It's a line located underground that carries all wastewater from your home to a municipal connection or septic tank, not just toilet water.
Does homeowners insurance cover your sewer line if it's damaged? Damage to your sewer line may be covered by your policy if it is caused by perils such as hail or windstorms, explosions, lightning or fire, damages caused by vehicles, vandalism or falling objects.
You will likely pay around $350 to $650 to have a plumber unclog a main sewer line unless you have complications like serious damage to the line.
Sewer line replacement costs stem from labor, permits, materials, excavation, and landscaping restoration, potentially running from $4,000 to $25,000. Trenchless sewer replacement methods can save long-term costs by minimizing disruption and avoiding extensive excavation, despite higher initial charges.
Generally speaking, you're going to find that most main sewer lines will only last somewhere between 50 and 100 years before you need to do a main sewer line replacement. You could very well have a broken sewer line on your hands right now and not even realize it.
Sewer laterals are the underground pipes that connect your home wastewater to the main sewer line in the street. Homeowners are responsible for their sewer laterals, while problems with the public sewer main line are managed by the city or municipality.
For instance, residential sewer line depth ranges from 18 to 30 inches. However, city sewer line depths are different. Your city's sewer lines must always be deeper than the deepest residential pipe to allow waste to flow downhill. As such, these lines can go as deep as needed.
your drain line. The main sewer line is outside the home, while drain lines are inside your house. When these systems need maintenance or repairs, the type of plumber you should call will depend on whether the problem is in a drain line inside your home or the main sewer line outside your home.
You may spot a 3 to 4-inch diameter pipe peeking out of the slab floor of the basement. The sewer drain pipe could be made of plastic or cast iron; it might be copper or brass in rare cases. The stub-out will have a screw-in plug coupled with a square-head lug on it, representing your access to the main drain.
At this point almost all homes have a sewer cleanout. The only houses that don't are older homes in which a cleanout wasn't installed originally. But even if you're in an older home that was built without a sewer cleanout, it's likely one was needed at some point and was installed.
Test Balls for Drainage Lines
To start the process, make sure your main line sewer cleanout is clear of debris and liquid. Next, insert the test ball and inflate it so that it blocks the main line. Fill the sewer system with water and observe the water level for 15-20 minutes.
As we mentioned above, it's certainly possible for a homeowner to perform sewer line replacement or sewer line repair. However, it's definitely not an easy job. When you replace the sewer line yourself you run the risk of causing even more damage.
One of the primary reasons for the high cost of sewer line replacement is the labor-intensive nature of the job. Replacing a sewer line involves excavating the ground to access the damaged pipe, removing the old pipe, and installing a new one.
Expert Recommendations for Sewer Line Cleaning
We recommend homeowners schedule sewer line cleaning every 18 to 24 months to prevent buildup and clogs. Regular cleanings help avoid costly repairs and extend the life of your plumbing system.
In most cases, home insurance will cover sewer line damage from specific events. This includes extreme weather (excluding earthquakes and floods), vandalism, fire, and damage from vehicles or falling objects.
Main drains are located in the walls and floors of your home, while sewer line drains are located outside underground. Each drain pipe in your home is connected to a different household fixture on one end, including toilets, sinks and bathtubs, and the other end is connected to the main sewer line.
Trenchless sewer repairs, such as pipe lining or pipe bursting, are typically 30-40% less expensive than traditional excavation and less invasive. Traditional excavation, which involves digging a trench to access the damaged pipe, is usually more expensive and can cause significant damage to your yard.
Typically, to replace a sewer line it can take anywhere from 1 to 2 days, to 3 to 5 days. In some rare cases, it may even be as quick as one day. Generally, the estimated time frame will depend on the layout of your property, your home's piping system, and the depth required to excavate.
Professional plumbers can use various camera styles to inspect the sewer line, such as: Remote-controlled crawler cameras. Pole or fixed zoom cameras. Push rod cameras.
