sewer backup situation

Any property experiencing a sewer backup will have a serious plumbing issue. It can be a disturbing sight to witness. The toilet drains and sinks on your premises or residence can cause sewage and wastewater to back into your space. You must take every precaution to steer clear of it. 

You must be wondering—what is sewer backup? It is a blockage or malfunction that prevents wastewater from draining away properly. This condition typically occurs in the central sewer line that connects the property to the public sewerage systems. Wastewater will keep filling your gutters and sewage lines if the problem does not get fixed right away, which will cause a backup. Your property may sustain significant damage from a sewer backlog, and the inhabitants may become ill.

This article will help you recognize sewer backup situations, how to eliminate them, and how to fix sewer backup in basements.

Top 6 Reasons for Sewer Backup

The answer to your question, “what is sewer backup?” is now present. The next and most necessary stage would be to determine the cause.

The six most likable explanations for why there is a sewer backup on your property are listed below.

1. Aging Sewer Systems

The aging sewer system is the most common reason people face sewer backups on their properties. Typically, Polyvinyl chloride, Ductile iron, Terracotta, or Orangeburg (a fiber pipe) are the substances that make sewer pipes. Although these substances are robust, they cannot last a long time. 

Furthermore, it is a verifiable fact that people neglect their plumbing apparatus after installation. Sewer pipes and drainage systems will inevitably corrode and disintegrate as they age. It is necessary to realize the connotation that these materials will eventually need replacement, and waiting till things worsen is not a sensible move. 

Sewer backup in basements and overflows have all increased significantly in recent years due to the rise in residences linked to existing deteriorating sewage systems. People need knowledge on how to fix sewer backup in basements. The pipeline and drainage system are no longer enough to tolerate increasing requirements resulting from years of depreciation, damage, and clogging. One way to resolve this problem is by checking the condition of your sewer system every 3-5 years, and you should clean up sewer backup in basements.

2. Heavy Rainfall or Too Much Melted Snow 

A surplus of water and waste particles enters local sanitary sewer systems during severe rain or continuous snowmelt, overburdening the system. It could back up into your facility’s sewage pipe and overflow, causing sewer backup in basements if there is too much water. 

It is most frequent when there has recently been a flood in your vicinity or during times with excessive snowfall. The extra water may cause the bottom to get saturated and raise the water level in the sewer system. Water may still enter your sewage line even if your house does not flood. Flooding can trigger a sewage backup that contains more than merely your debris.

The sewer system in your neighborhood may flood entirely if the local pump station floods. This issue gets worse in case of a power outage throughout the flood. Power is used in many treatment facilities, including sewage ones, to maintain return valve seals. All types of waste can continue to flow up sewers if they falter. 

3. Broken or Collapsed Sewer Lines

A sewage backup is also frequently caused by cracked or collapsing sewer lines. Like the local drainage pipes in your house, your main sewer line can jam or get stuck. If additional materials get washed or dumped into the sewer that should not be in the first place, they can cause a backup because the main sewage line is only big enough for untreated sewage to flow through.

If the overflow results from a single clogged drain, you will only encounter issues with that one drain. However, if it originates from your property’s main sewage line, you may suffer plumbing problems with bathrooms or sinks.

Instead of merely affecting one drain, a sewer line obstruction will concurrently damage most of your plumbing across the entire property. In such cases, turn off your home’s water supply to reduce damage and attempt to line drain valves with materials that can absorb liquids.

4. Tree Roots 

Sewer pipes frequently experience issues due to tree roots. The water and other elements in your sewer line are sought after by vegetation such as trees. After the tree roots have reached your pipes, they frequently keep expanding and obstructing them.

Tree root obstruction is particularly prevalent in old buildings. The sewer lines in most old residences constitute earthenware pipes, which are vulnerable to splitting. Roots of trees or other plants may utilize even tiny gaps in the earth. Also, the base of earthenware pipes is particularly permeable; even if it does not shatter, tree roots might cling to it and cause problems later.

These obstructions are common during dry months or periods of drought. Plants such as trees and shrubs sought out additional suppliers of water because the soil is so parched; the closest energy option could be your sewer line.

5. Cracked or Deteriorated Sewer Lateral

Geological mobility and inadequate ground stability can weaken sewer lateral, resulting in pipes that break or crash. It is another issue frequently affecting old buildings with metal or clay-based pipe systems.

A chipped, torn, or ruptured line may cause sewage to back up. Steel pipelines also can degrade over time, leading to oxidation that consumes the pipes. 

The pipes in your property may become dented if you reside in a region that experiences earthquakes or other earth tremors. The natural occurrences are beyond your control, but again, the aged the pipe, the more probable it is to sustain deterioration.

Thankfully, deep foundation pipe repair, a service procedure that involves no disruption to your property or land, can help fix numerous deteriorated sewer laterals.

6. Blockages in City Sanitary Mains

It can be that your town, municipality, or county owns and is responsible for the pipeline that is your mainline sanitary sewage system and is where blockages occur. The mainline sewage clog is comparable to a domestic clog and may be the source of the obstruction. If your neighborhood is experiencing an exponential rise in sewage issues, it can also be due to a lack of computational resources. If a municipality experienced sewage issues following significant rains, this issue becomes apparent and needs time to resolve.

If this occurs, the only thing you can do to resolve the issue is to contact your neighborhood authority. Your properties’ basements are more likely to experience this because congested public sewage lines can create sewer backup in basements. The fact that this happens progressively is a plus since it gives you time to have a qualified plumber evaluate the harm. For instance, they will clean up sewer backup in basements for you.
