Basements are a valuable space in any home, providing additional living or storage areas. However, one of the most common issues that homeowners face with their basements is flooding. Basement flooding can cause significant damage to property and pose health risks due to the presence of sewage. To address this problem, sewage ejector pumps play a crucial role in preventing basement flooding.

Understanding Sewage Ejector Pumps

Sewage ejector pumps are devices designed to remove wastewater and sewage from the lower levels of a building, such as basements, where gravity drainage is not possible. These pumps are typically installed in a dedicated pit or basin, below the level of the drainpipes. When wastewater from various sources, such as toilets, sinks, and showers, enters the pit, the pump is activated and pumps the waste up and out of the basement, connecting it to the main sewer line.

One of the primary reasons sewage ejector pumps are installed is to prevent basement flooding. These pumps ensure that wastewater is efficiently and safely removed from the basement, reducing the risk of water damage and contamination. Let’s explore some of the key roles sewage ejector pumps play in preventing basement flooding:

1. Efficient Water Removal

Sewage ejector pumps are specifically designed to handle the solid and liquid waste found in wastewater. These powerful pumps can effectively remove large volumes of wastewater from the basement, ensuring it is swiftly and efficiently transported away from the property. By promptly removing excess water, the risk of basement flooding is significantly reduced.

2. Prevention of Backflow

Backflow occurs when wastewater flows back into the basement due to issues in the sewage system, such as a blockage or overload. This can happen during heavy rainfall or when the sewer system becomes overwhelmed. Sewage ejector pumps help prevent backflow by actively pumping wastewater out of the basement and into the sewer system, ensuring that water flows in the intended direction and doesn’t reverse its course, leading to potential flooding.

3. Protection Against Sinkhole Formation

If excess groundwater enters your basement due to heavy rain or improperly drained landscaping, it can weaken the soil beneath your foundation and lead to sinkhole formation. Sewage ejector pumps help mitigate this risk by removing any excess water before it seeps into the soil. By removing the water promptly, the pumps prevent soil destabilization, ensuring the structural integrity of your foundation remains intact.

4. Overall Home Safety

In addition to preventing basement flooding, sewage ejector pumps contribute to the overall safety of your home. Flooded basements can pose electrical hazards and promote mold and bacterial growth. By efficiently removing wastewater and preventing basement flooding, sewage ejector pumps minimize the potential for these hazards, creating a safer and healthier living environment.

To ensure the proper functioning of sewage ejector pumps and prevent basement flooding, regular maintenance is essential.

Maintenance and Considerations

To ensure the proper functioning of sewage ejector pumps and prevent basement flooding, regular maintenance is essential. Here are a few considerations to keep in mind:

  • Schedule annual inspections and maintenance by a professional plumber to identify potential issues and ensure proper pump operation.
  • Test the pump regularly by pouring water into the pit to verify that it activates and pumps the wastewater out of the basement effectively.
  • Avoid flushing items like diapers, paper towels, or other non-biodegradable materials, as they can clog the pump and impede its performance.
  • Consider installing a high-water alarm system that alerts you if the water level in the pump pit rises above a safe threshold.

By following these maintenance tips and considering the necessary precautions, you can maximize the efficiency and lifespan of your sewage ejector pump, reducing the risk of basement flooding and ensuring its consistent performance over time.

Conclusion

Sewage ejector pumps play a vital role in preventing basement flooding by efficiently removing wastewater from basements where gravity drainage is not possible. These pumps effectively prevent backflow and protect against sinkhole formation, contributing to the safety and integrity of the home. Regular maintenance and considerations are essential to ensure the proper functioning of sewage ejector pumps. By investing in the installation of a sewage ejector pump and taking appropriate precautions, homeowners can safeguard their basements against flooding, promoting a secure and healthy living environment for their families.

Everything You Need to Know About Sewage Ejector Pumps

Sewage backup is one of the most damaging plumbing emergencies you can have in your home. Imagine the horror of sewage flowing into your home, not only ruining your floors and belongings but also subjecting your home to terrible smells. If you’re a landlord, you already know this means your property will be deemed uninhabitable. This is a plumbing issue you can certainly do without.

One trusted way to prevent this problem in your home is to install a sewage ejector pump in the house. But what is a sewage ejector pump? How does it work? What do you need to know before installing a sewage ejector pump in your home?

What is a sewage ejector pump?

A sewage ejector pump operates on the same principle as a sump pump. Just like a basement sump pump, this system comprises of a pump housed inside a basin. This basin or holding tank, along with its pump, is located below ground inside the home.

But unlike a sump pump system, which is designed to remove floodwater entering the home, a sewage ejector pump system holds wastewater from the home before pumping it into the main sewer lines in the street.

How does a sewage ejector pump work?

  • Waste from the various plumbing fixtures in the home flows easily into the basin because the drain lines are sloped down into the sides of the basin.
  • For a moderate-sized home, the basin can hold up to 30 gallons of waste. This water will stay inside the basin until it reaches a certain level.
  • Inside the basin are movable floats that rise with the water level. When the water in the basin reaches the threshold, the flotation device triggers a switch to activate the pump.
  • The pump removes the wastewater by raising it to the level of the main sewer line in your home or the city sewer lines in the street.
  • Once the basin is emptied to a specified level, the pump shuts down.
  • But before the liquid is pumped out of the basin, it passes through a grinder inside the sewage ejector, which breaks apart the clumped solid waste.
  • Most sewage ejector systems have a water level alarm that triggers when the water in the basin rises to a certain level. If this alarm goes off, it means there is a problem with the pumping mechanism.
  • A lot of sewage ejector systems are equipped with a secondary pump which serves as a backup when the main pump fails or is being repaired.

Does your home need a sewage ejector pump?

Your home needs a sewage ejector pump if the bathroom, laundry, or any plumbing fixture in the house is located at a level below the main sewer lines in the street. Where the municipal lines are located higher than a fixture in the home, wastewater will not flow properly.

This is because the flow of wastewater from your home depends on gravity. In order to flow freely, water must be able to move in a downstream fashion. In other words, your home’s plumbing fixtures must be located at a higher level than the city’s sewer lines.

Ejector pumps are also needed in homes with a septic drain-field system, such as those found in rural areas. Without a sewage ejector system, homes that fit the above description run the risk of sewage backing up into the basement or sewer gas seeping into the home.

Before you install a sewer ejector pump system

What do you need to know or get before installing a sewage ejector pump system in your home?

  • A permit – In most locations, you will require a permit to install a sewage ejector pump system in your home. This is because of the potential damage to the city’s sewer lines if your home’s sewage ejection pump is not properly installed.
  • Budget – Sewage ejector pumps cost anywhere from $400 to $1000. This price depends on the size and brand of the pump. If the pump system will not be subject to heavy use, you can get away with buying a less expensive one. But you really don’t want a system that you will have to repair often. Worse, if the pump fails it can cost you tens of thousands of dollars worth of damage.

Other system components – In order to function properly, the system needs the following:

  • A sump basin – The underground tank where sewage water is stored until it is removed.
  • Vents – Vents help to equalize air pressure and also provide an outlet for sewer gases.
  • Check valve – This is located between the outlet pipe and the main sewer line, to prevent backups.
  • The right contractor – Due to the critical role of the sewage ejector system, this is not a job you should attempt to do yourself. It is best to hire a skilled plumber for an ejector pump installation.
