How Your Sewer Drain Works And Everything Else?

Sewer drains are found under sinks or toilets, and they connect to the main drainage system. They remove waste from the sink or toilet and send it into the sewage system.

Sewer drains are also known as sanitary sewers, storm drains, and combined sewers. When the water flows through them, it picks up solid particles such as paper, food scraps, and other debris. This material gets flushed down the drain and eventually ends up in the local sewer system.

When the sewer line breaks, it creates a backup of wastewater and sewage. If this happens, the city will usually call a plumber to fix the problem.

Your sewer drain system is essential to keeping your home clean and free from nasty smells. Unfortunately, it can also become clogged or damaged over time. If you want to prevent these problems, then you should take a look at this guide.

Sewer drains are responsible for removing waste water from your house. They consist of pipes that carry wastewater away from your property. These pipes usually run under your yard and into the ground. The main purpose of a sewer line is to remove solid waste such as food scraps, toilet paper, and other debris from your home.

There are two types of sewers: gravity sewers and force sewers. Gravity sewers rely on gravity to move waste through the pipe. This type of system is common in older homes. Force sewers require pumps to push waste out of the pipe. This type is commonly found in newer homes.

How Your Sewer Drain Works – And Everything Else

The first step when dealing with any plumbing issue is to shut off the water supply. You do not need running water while working on your plumbing. Once the water has been turned off, open all faucets and let everything drip until the problem is fixed.

If you have an old leaky toilet, try using baking soda to stop the leak. Mix one part baking soda and three parts water in a bucket. Pour this mixture around the base of the toilet bowl and leave it there overnight. In the morning, check if the leak has stopped. If so, flush the toilet again to get rid of the residue.

If your toilet won’t flush properly, pour some vinegar down the toilet’s drainpipe. Wait ten minutes and then flush the toilet. Repeat this process once every day until the problem goes away.

If you have a slow-running garbage disposal, pour hot water down its drain. This should clear up most issues. To unclog a blocked sink, pour boiling water down the drain. Let it sit for about five minutes before flushing.

To unclog a bathtub drain, pour half a cup of white vinegar down the drain. Allow it to sit for 15 minutes before flushing. Vinegar works best because it dissolves grease and soap scum.

To unclog a kitchen sink, pour a little bit of dishwashing liquid down the drain. Wait for it to dissolve and then flush the sink.

If you have a backed-up shower, pour a few drops of ammonia down the drain. Wait 10 minutes and then flush. Ammonia works well because it removes lime deposits from the pipes.

How Does Sewage Leave Your House?

You might wonder how sewage leaves your house. It does so through a drainage pipe called the storm drain. Storm drains are located along streets where rainwater flows into them.

Rainwater picks up pollutants like dirt, oil, and chemicals. After picking up these contaminants, the water enters underground tunnels called sanitary sewers.

Sanitary sewers collect sewage from houses and businesses. When they reach capacity, the excess sewage overflows into nearby bodies of water. Sanitary sewers are designed to handle large amounts of sewage at one time.

Storm drains are smaller than sanitary sewers. They are used to transport small amounts of water from street intersections or parking lots.

How Does a Domestic Sewage System Work?

A domestic sewer system consists of many components. The main component is the sewer line. A sewer line runs underneath your home from the building’s foundation to the city sewer connection.

Sewer lines typically consist of four sections: (1) the manhole; (2) the service lateral; (3) the distribution lateral; and (4) the forcemain.

A manhole is a round opening that allows access to the sewer line. Manholes can be found at road crossings, driveways, and other places.

A service lateral is a section of pipe that connects a property owner’s sewer line to the public sewer system. Lateral lines usually run parallel to the property owner’s main sewer line.

A distribution lateral is a section of piping that carries wastewater from several properties to the main trunk line. Distribution laines are also known as “service loops.”

A forcemain is a long piece of pipe that transports wastewater from a treatment plant to a river, lake, or ocean. Forcemains are often placed near a body of water.

The next part of the sewer system is the collection system. Collection systems include catch basins, soakaways, and dry wells.

Sewer Line Inspection and Cleaning

Before digging a new sewer line, you need to inspect the existing sewer line. Inspections help prevent costly problems later on.

During an inspection, make sure there aren’t any cracks in the sewer line. Cracks allow pollutants to enter the sewer line. If you find a crack, repair it immediately.

After inspecting the sewer line, clean out the old sewer line using a vacuum cleaner. Vacuuming helps remove debris from the sewer line.

Clean out the manhole cover with a garden hose. Use a brush if necessary. Make sure you don’t damage the manhole cover.

If you find clogs in your sewer line, use a plunger to dislodge them. Plungers work best when you push down on the plunger rather than pull it.

If you suspect your sewer line has been damaged by roots, try removing some soil around the manhole. Roots can cause serious blockages.

When cleaning out the manhole, wear protective gear. Wear rubber gloves and boots. Cover yourself with waterproof clothing.

You should also check for leaks after cleaning out the manhole. Check all connections between pipes. Look for cracks in joints.

Finally, seal off the manhole with caulking. Caulk seals gaps so no more air gets trapped inside.

What Happens After You Dig a New Sewer Line?

Once you have inspected and cleaned out the existing sewer line, you can start digging. Before digging begins , contact your local utility company.

Digging a new sewer line requires permits. Utility companies require permits before they dig trenches. Obtain these permits before beginning construction.

Once you get the permit, call a licensed contractor who specializes in trenching. The contractor will dig the trench.

Your contractor may hire subcontractors to do specific tasks. For example, he may hire someone to install concrete lining, another person to lay the pipe, and still others to excavate the area where the pipe will be installed.

Your contractor will then backfill the trench with dirt. Backfilling prevents groundwater from entering the trench.

Backfilling also keeps the trench from collapsing during heavy rains. When the trench is filled with earth, you can begin installing the pipe.

What Causes Sewer Drains to Clog?

There are many reasons why drains clog. Some common causes include:

Debris – This includes hair, food particles, soap scum, and other materials. These items can plug up the drain.

Grease – Grease can build up over time. It collects at the bottom of the sink or tub.

Soap Scum – Soap scum builds up in sinks and tubs. To clean this problem, use a soft-bristled scrub brush.

Fats and Oils – Fatty substances such as cooking oil, butter, grease, and salad dressing can collect in drains.

Fruit Seeds – Fruit seeds can grow into tree roots that eventually block drains.

Plumbing Problems – A plugged toilet or shower drain can lead to plumbing problems. In addition, a blocked sink or bathtub drain can lead to flooding.

Tree Roots – Tree roots can grow into sewers and block drains. They can also break through the walls of the sewer system.


Sewer lines are essential parts of our homes and businesses. Proper maintenance ensures that they function properly.

This article provides information about how your sewer works. We hope you found this helpful. A sewer is a large underground drainage pipe which is used to carry wastewater away from buildings.

A sewer usually consists of a main trunk (or pipe) which branches out into smaller pipes called laterals. Each lateral carries water away from the trunk.
