How Sewage Ejector Pumps Work

A sewer ejector pump is necessary to help make sure that wastewater flows away from your home. Not everyone will require a sewer injector pump, but if you do, there are several things that you will need to learn about the system. Ensuring that it is professionally installed and works well will ensure that you will never have any issues with any wastewater backing up into your home.

What Is A Sewage Ejector Pump?

Sewage ejector pumps need to be used when the plumbing is located below the septic line or main sewer line level. When wastewater drains, it depends on gravity to go where it needs to go. If your fixtures are lower than the sewer line, it may pool and back up into the house. This pump will help to elevate the wastewater so it can get into the sewer line appropriately. Sewer ejector pump works similarly to a groundwater sump pump.

Pump Systems in Homes

It is typical to find these pump systems in homes that have laundry rooms or bathrooms located in the basement. If you have a city sewer line that runs in the street, they will be at a higher level, and an ejector pump will be needed. These ejectors are also often found in rural settings where the drain field or holding tank is higher than the plumbing.

The pump system needs to be placed in the sump basin. This is cut into the ground, which is below the grade of the home. Each sump can pump out 30 to 40 gallons of waste at a time. Drain lines from the basement area will be sloped down and ran into the ejector pumps. It will have a level where when the wastewater reaches it and will kick on and start the process. The wastewater will then be removed from the basin and will go into the sewer or septic system. When the basin is empty in the float will drop, the pump will turn off and wait until it is full again.

Requirements For Pump Systems

There are several requirements that will be needed when the sewer ejection pump is installed.

  • Vents. To have a sewage ejector pump installed correctly, you will need to have a vent installed. This vent helps to equalize pressure when it is pumping to help the sewer gases to escape. The vent will be placed through an existing vent or through the roof.
  • Check valve. It is imperative to have a check valve installed with your sewage ejector pump. This is found in the outlet pipe that leads to the main sewer line. This check valve will keep any wastewater from coming back into the sump basin after it has been pumped into the sewer line. This will also help to ensure that there is no smell coming out of the basin.
  • Size. You will need to consider the size of the ejector pump that you will need. There are various sizes for these. If you have an average size home, there will be a standard pump kit that has ½ to ¾ hp motor and pushes around 30 to 40 gallons of wastewater out. You will need to ensure that you get the correct size to ensure that wastewater does not back up into your home. If you are unsure of the size that you need, talking to a reputable plumber in your area will help you determine what size pump you need.
  • Budget. A sump pump ejector system can run anywhere from $400 to $1000. The price will depend on the size that you need and the brand you get. You will want to make sure that you purchase quality equipment when buying a pump system. You do not want to repair the system as it is often difficult, and an entire replacement is often needed instead of repair. If you purchase through a local plumber, you may get discounts, especially if you have them install it. Make sure you take the time to do your research to find the best ejector pump out there that you can afford.

Checking Codes

Before you start the process of installing sewage ejector pumps, you will want to call your local building department to determine what the codes and requirements are. Each area may have different requirements when it comes to plumbing. You may be required to get a permit, and you may have to get it inspected. It is a good idea to have a professional plumber do this for you as they know all the local codes and regulations when it comes to installing these pumps.
