what causes sewer backflow water

The issue of water entering structures via a city sewer line, also known as sewer backflow water or backwater, is the subject of this article. The causes of this problem will be examined, and solutions will be offered to fix it.

Building owners frequently complain about the widespread issue of sewer backflow, especially in areas like New York where it rains a lot. When water from the city sewer line backs up into the structure, it brings with it all the dirt and debris that are in the sewer line, which is where the issue starts. Contrary to what was intended, this flow caused the dirt to be carried away by the water as it left the structure. This results in an unpleasant and uncomfortable situation, a potentially hazardous situation for those living in the building, particularly in the basement and cellar areas.

The purpose of this post is to explain how this problem occurs and provide effective solutions to prevent it from happening. By understanding the causes and preventative measures, building owners can take steps to protect their properties and avoid the costly and unpleasant consequences of sewer backflow.

Why does Sewer backflow happen?

There are several following common reasons that cause backflow

Heavy rain or flooding

Sewer backflow is frequently caused by prolonged periods of heavy rain or flooding. The sewer system may become overloaded with water during a heavy downpour. Wastewater may flow back into the house as a result of pressure buildup in the pipes brought on by the extra water. Significant damage and health risks may result from this.

Systemic Blockages in the Sewers

Another frequent reason for sewer backflow is obstructions in the sewer system. Debris accumulation, grease buildup, and other substances obstructing water flow through the sewer pipes can result in blockages. The pressure that builds up due to improper water flow may force wastewater to flow back into the house.

Malfunctioning or Inadequate Sewer Infrastructure

Malfunctioning or inadequate sewer infrastructure can also cause sewer backflow. If the sewer system is not properly designed or maintained, it can become overwhelmed during heavy rainfall or flooding. The pipes may not be able to handle the amount of water flowing through them, leading to sewer backflow. Additionally, if the sewer pipes are not installed correctly, they may not function as intended and may cause sewer backflow.

Improperly Designed or Installed Plumbing Systems

Improperly designed or installed plumbing systems in homes can also cause sewer backflow. If the plumbing system is not designed to handle the amount of water flowing through it, it can become overwhelmed during heavy rainfall or flooding. Additionally, if the plumbing system is not installed correctly, it may develop blockages that can lead to sewer backflow.

Backpressure from the Public Sewer System

Backpressure from the public sewer system is another common cause of sewer backflow. When the water level in the public sewer system rises, it can create pressure that pushes water back into homes. This can occur if the public sewer system is not properly designed or maintained or if there are significant changes in the pressure within the system due to other events such as nearby construction work.

The solution for Sewer water backflow problem

To start addressing the issue of sewer backflow, it is highly recommended to seek the assistance of a licensed plumber to inspect and maintain your building’s plumbing system on a regular basis. This proactive measure can help to identify any potential issues before they become serious problems that could potentially damage the entire system. The plumber can also carry out periodic cleaning to ensure that water flows smoothly and effectively throughout the system.

Backwater prevention valve

Installing a backwater prevention valve is another highly effective solution. Given the recent climate changes and increased flood levels in New York City, it is crucial for every homeowner to have a backwater prevention valve in their sewer system. This can provide vital protection against sewer backflow and ensure that the wastewater flows in the intended direction.

In addition to installing a backwater prevention valve, there are other steps that can be taken to reduce the amount of water that enters your building’s sewer system and eventually flows into the city sewer. Installing a rain barrel or redirecting your gutter downspouts to a grassy area where the water can be absorbed by the soil are both effective measures that can be helpful.

How a sewer water backflow valve works

A sewer water backflow valve, also known as a backwater prevention valve, is a device that is installed in the sewer line to prevent wastewater from flowing back into your home. This valve is designed to allow water to flow out of your home but will close when water begins to flow back in. Understanding how a sewer water backflow valve works is crucial to preventing sewer water backflow and protecting your property.

A backwater prevention valve typically consists of a flap or gate that is installed in the sewer line. The flap or gate is designed to allow water to flow out of your home but will close when water begins to flow back in. This prevents any wastewater from entering your home and causing damage or posing health hazards.

The valve operates automatically, which means that it does not require any action from the homeowner to function. When water flows out of your home, the valve is open and allows water to flow through the sewer line. However, if water begins to flow back into your home due to heavy rainfall, blockages in the sewer system, or other issues, the valve will automatically close to prevent any wastewater from entering your home.

Backwater prevention valves can be installed in a number of places, including outside in a manhole or in the basement or crawl space of your home. The layout of your home and the sewer system will determine where the valve is placed.

Backwater prevention valves must be regularly maintained to ensure proper operation, it is important to note. This may entail inspecting the valve for wear and tear or damage and cleaning it. The valve’s installation must be done correctly, and it must be the right size for your house’s sewer system.
