What is a sewer line?

The sewer line is a single tube that transfers all your wastewater from your house to the main sewer below the street. The pipe passes across your front yard, a few meters below the frost level.

This sewer line is located below the yard and is considered a component of your plumbing system. Drainage lines usually have a diameter of 4 to 6 cm and are inclined down to promote water flow from your property to your city sewer.

Causes of sewer line damage

Tree roots

Tree roots are one of the leading external causes of sewer system difficulties. Tree roots are drawn to the wastewater fertilizer. As roots develop around your pipes, they produce cracks to collect these nutrients. Tree roots have known to destroy or fill whole sewer lines. Even if you don’t have trees in your garden, your plumbing nightmare may become a neighbor’s tree.

Sagging into sewer line

While this is out of the control of a homeowner, the draining sewer lines occur over time. This gloomy pipe develops when a part of the pipe falls owing to soil or soil conditions.

The low point on the pipe starts collecting paper and garbage, resulting in repeated obstructions.

Corrosion developed into pipes

While iron and steel pipes are galvanized to reduce rust, the corrosion risk is high due to the regular wear and tear of calcium and magnesium. If the corrosion is left unchecked, the pipe can remain leak-able and crack-able.

Clogging of pipes due to debris

In your home, the drainage lines are only prepared to handle human waste and toilet paper. Do not flush waste like towels and wrappers, for they cannot correctly decline, and drainage agents cannot restore blockage. Kitchen oil and fat can potentially clog pipes if they are poured into the sink. Pour these liquids into a container, chill, and place in a basin.

Symptoms of basement sewer pipe problems

Significant change in basement

A change in the texture of your basement or basement plate could also signal a problem. If you go barefooted and stumble at water areas or soft patches on your basement, this can signal a drainage problem.

Foul-smelling yard

Other difficulties arising from a broken sewage connection in the basement include water draining through the concrete, expanding fractures or separation settlers, and unpleasant aromas which could occur in the sewage or mold development.

Draining difficulties

While a pipe that leads directly from a hack or shower produces some blockages, blockage in the central sewage system may be detected if many drainage locations are blocked at home. Toilets can warn of severe obstructions if odd gurgling sounds occur when the air is forced back up the pipe.

Water damage in the home

Water damage can happen when the drainage pipe leaks or breaks at home. Mold spreading on the floors or the walls is one of the first indicators.

Can you replace a sewer line yourself?

You, as a homeowner, can easily do sewer line replacement or sewage line repair. It’s not an easy job. If you don’t follow the instructions correctly, you can harm yourself if you replace the sewer pipe yourself.

Sewer line repair and replacement (2 Options)

Option-1: Dig a trench around the sewer pipe

Are you searching for how to replace cast iron sewer pipe by digging a trench? Then follow the below steps.

Step 1: Select right location

One of the most critical phases in excavating a sewage replacement trench is to make sure you dig at the correct area. You can find a video camera examination if you have no idea where your sewer line travels. Be as precise as possible since, in unnecessary labor, you will pay a significant price to dig in the wrong place.

Step 2: Establish the Utility Lines

This usually is a free service to people funded and administered by public utilities. Then your yard technicians should mark water, gas, and other vital services. Do not forget that there may be additional homeowner services in your yards, such as sprinkler lines and paisa lights; utility companies won’t identify these.

Step 3: Take Steps to Get Permission

Your municipality is very likely to require a permit as a security measure to make sure the work is done correctly. An inspector visits the workplace to ensure that the work has been carried out according to the code. For the replacement of a sewer line, this is usually done after installing the new sewage line but before the trench was filled.

Step 4: Break or Remove Obstructions

You may have to remove barriers such as concrete or brick sidewalks, roads, or slabs before you can reach the ground. Use an 8-pound hammer to break up the concrete from the edge. An electric jackhammer should be rented out in a tool rental center for massive cement buildings.

Step 5: Dig the Sewer Trench

You should dig straight down, limiting as much digging as possible. You will have to extend the trench later to stand in the pit and make access to the sewer. But dig as little as you can till the sewer line is identified.

Step 6: Cut Tree Roots

If you dig, you might have to trim or see tree and shrub roots when you meet them. You can cut down some tiny roots.

Tip

It is helpful to have a spade you may save for tree roots chopping. Keep the blade end sharp with the corner grinder.

Step 7: Assess the Sewer Line Problem

If your sewer problem is an emergency, before you see it, the pipe may smell. You may discover the soil wet by wastewater.

It is vital to protect the trench against animals or children who fall into the water until the sewage repair is complete. This can be achieved by covering the trench or installing a robust temporary fence to protect it from incursion.

Step 8: Finish the Project

Once the sewer substitution is complete, ensure that work is examined before the trench is filled with gravel and soil. When you fill the trench, regularly compress the soil to prevent the ground from settling.

Option-2: Trenchless sewer line repair

I recommend you adopt a trenchless sewer line substitution because the cost to replace underground sewer pipe by following this process is less. This process is environmentally beneficial and avoids interruptions from ordinary residential activities. Furthermore, trenchless sewer replacement lasts longer and prevents further repairs in the future.

Do you want to know how to replace sewer pipe by performing trenchless sewer line repair?

In Pipe Spy, an inspection service should be performed to confirm the problem with the sewer in your basement. During the inspection, we often find out whether the line is encircled inside the concrete or located farther below the plate itself.

Once determined, you should ensure that the property’s concrete platform does not endanger electrical conduits or radiant heat piping. In addition to the original problem, the wrong move and an owner can finally replace costly systems. Next, you would conduct the repair process without a trench, effortlessly replacing the old pipe with a brand new pipe in your basement or beneath your concrete plate foundation.

Replacing sewer pipe in the basement via trenchless

Pipelining:

If there is minor damage to your pipes, the pipes can be utilized to put an epoxy-covered inflatable tube into your tubes. The tube is inflated from there, pressing on the existing line. The epoxy heals and hardens against the existing sewage pipe, fixing the leak. You can then remove the inflatable pipe and repair the sewer line.

Pipe bursting:

If a sewer line is damaged too much to apply the pipe filling procedure, a more invasive trenchless repair can be carried out. Technicians feed your existing line with a cone-shaped bit and destroy the tube while replacing it with a new one. This procedure is more expensive and less time-efficient. However, massive excavations are not necessary.

If your pipes are damaged beyond repair, you might need to use standard sewer line substitution procedures. This highly invasive and expensive approach involves experts digging up their yards to reveal damaged or broken cables. Excavation is indeed necessary if the sewage system of your property suffers considerable damage. 

Average Cost to Replace Sewer Pipe

It isn’t fun to replace the sewer pipe in your basement. It is stinky, dirty, hard, and complicated—and a lot may go wrong if you don’t know exactly what you’re doing. Do you know how much does it cost to replace a sewer pipe?

Average sewage replacement from one house to the public sewer generally starts at about $3000 but may vary from $7,000 or more depending on the complexity. The charges are usually between $60 and $200 per foot.

Final Words

If your sewer line flows or romps and has to be fixed, there are two ways for you to dig a trench or repair the sewer line without trenching. A sewage repair without trench is time-efficient when excavating little or no. It is also essential to understand the warning signals that your wastewater system has a problem. These include multiple slow drains, bubbling sounds from the toilet, or other weird plumbing activities in your house. If your sewer line is of concern, it is recommended that you react as soon as possible.
