How to Prevent a Sewage Back-up

How to Prevent a Sewage Back-up.

Sewage back-ups can be an absolute nightmare for homeowners. Between the astronomical costs of physical damage, they can cause, and the mental toll repairs can take, it’s best to take preventative measures beforehand.

Thankfully, there are tell-tale signs to look out for and steps homeowners can take to stop sewage back-ups in their tracks. Read on to learn more about the main causes of sewer leaks and how to prevent a sewage back-up from the get-go.

What Is a Sewage Back-up?

A sewage back-up occurs when an object blocks a home’s outgoing sewer line that connects to municipal sanitary sewers. This blockage causes a build-up in the drainpipes and backs up into your home. The result can lead to contamination issues including flooding, mold growth, and deteriorating property.

Sewage backups are one of the biggest headaches homeowners can deal with.

It’s imperative to take care of any damage as early as possible. Be on the lookout for suggestive signs such as slow drains throughout the house, waste backing into the wrong pipe, a greater quantity of sewage, and waste reverse-flowing into the home. Ignoring a sewage back-up can mean thousands of dollars literally down the drain.

Costs can include the fees of cleaning up and repairing floors, electrical systems, walls, furniture, and carpeting. Not to mention the numerous health hazards associated with nasal and oral exposure to germ-laden sewage water.

What Causes a Sewage Back-up?

Typically caused by natural occurrences, sewage back-up signs range from a visibly damaged sewer line from heavy rainfall to invading tree roots growing in pipe cracks and gaps. Read on to learn what you need to be on the lookout for.


Clogs can be the first indication of a sewer back-up.

Sewage back-ups are inevitable when one or more pipes becomes clogged with hair, grease, or other solid materials that tangle and prevent a healthy flow of water. To prevent a sewage back-up and any clogs, avoid pouring fats, oils, or melted butter down the kitchen sink, flushing feminine hygiene products, thick wipes, paper towels, or diapers down the toilet, and washing hair, hardened toothpaste and soap fragments, or solid makeup products down the bathroom sink.

Tree Roots

Roots can do serious damage to your plumbing system.

Tree roots naturally grow towards a water source. Even the smallest of cracks in your plumbing can attract the biggest tree roots. Over time, tree roots can cause major damage to your pipes.

Even if you cannot visually spot any plants or trees on your property growing near your pipes, there is a chance that extensive roots from your neighbor’s trees could be the assailant.

Heavy Rainfall

Heavy rainfall can cause your plumbing system to clog.

In the following days of a detrimental downpour, always check your home’s basement and pipes for floods that may indicate backflow from your pipes. On average, the nation’s sewer lines are over 30-years-old, according to data from the American Society of Civil Engineers.

Wear-and-tear over the years can worsen and be greatly damaged by heavy rainfall. But there are few things you can do to lessen the blow of a storm.

By disconnecting downspouts, foundation drains and weeping tiles from the municipal drain, and installing rain barrels to collect rain and prevent runoff, you can put your house in an optimal condition to avoid back-ups.

Damaged Sewer Line

Aging sewage systems can dilapidate and deteriorate over time, making your main sewer line susceptible to cracks and leakages

Aging sewage systems can dilapidate and deteriorate over time, making your main sewer line susceptible to cracks and leakages. All your home’s drains rely on the main sewer line in order to drain properly.

So, if there are blockages occurring in multiple drains, the problem can be traced back to the main sewer line.

How To Prevent a Sewage Back-up

Avoid Pouring Grease Down the Drain

Since grease and fatty substances can harden in cooler temperatures, they may form a barrier in your pipes, which leads to clogging. And despite what you may have heard, washing down grease with hot water will not prevent this hardening from happening.

Instead, try a natural method of unclogging drains by pouring one cup each of baking soda, white vinegar, and warm water down the drain.

Have Your Lines Cleared Every Few Years

If you are unfamiliar with the complex systems involved with residential plumbing and sewer systems, consider contacting an expert in plumbing repair.

Expert plumbers can examine the current state of sewage pipes, detect slab leaks, flooding faucets and other potential issues. They can recommend how to avoid back-ups from occurring in the future.

Cleaning your lines every few years will help diminish issues that can become severe without intervention as well as help you avoid clogs and lingering foul smells in your home. Oftentimes cleaning your sewer line is necessary to get your system working again.

However, it’s not always a permanent fix as physical damage caused by a root intrusion, for instance, requires a line replacement.

Work On Tree Root Maintenance

If tree or shrub roots prolifically grow in your sewer lateral, you may have to have a professional regularly cut the roots or replace your pipes with a plastic alternative. For minor roots, trim them periodically to inhibit their growth from reaching a point where serious damage can be caused.

Conduct Regular Sewage Pump Maintenance

Ensure your sump pump is not perched atop debris such as silt or gravel, which could be sucked into the pump and damage the motor. Make sure it’s placed on a steady flat brick instead. It also helps to put a filter fabric around the sump pump to prevent debris from entering and causing a blockage in the pipes.

Now that you’ve learned the causes of sewage back-ups, check your pipes to see if there is anything that needs extra attention from your local plumbing repair experts. Minor issues can sometimes be handled without the need of an expert, but do not ignore or delay problems affecting your main sewer line. Handling contamination damage yourself can also put you at risk for bacterial illnesses, so contact Moore HVAC immediately if you think your sewage system is damaged.
