Sewage ejector pumps are designed to pump your home's raw sewage into a septic tank or gravity flow sewer main. Therefore, they can only pump up to 750 feet. However, one of the benefits of sewage jet pumps is that they can move up to 200 gallons of raw sewage per minute. This is significantly higher than what a septic grinding system can pump. Typically, wastewater jet pumps are designed to handle large volumes of wastewater at low pressure.

While sewage jet pump systems and septic tank grinder pumps both pump raw sewage from your home to another destination, they do so in different ways. For example, a sewage jet pump does not have grinding blades like a grinding pump. Instead, they use a rotating impeller to push raw sewage out of the bottom of the pump. Pressure is then used to force the effluent into the discharge pipe.

septic tank grinding pump

Septic tank grinding pumps are high pressure/low volume systems. This means they are better suited than sewage jet pumps for transporting small amounts of raw sewage over long distances. If you need to move sewage to a pressurized sewer main, a septic tank grinder pump will help you achieve this goal.

Septic tank grinding pumps contain blades that grind raw sewage into a slurry before discharge. From there, it is sent to the pressurized sewer main.

Septic tank pumps should not be used with septic systems because the slurry is finely ground and does not separate from the liquid once it enters the septic tank. This means it won’t be sent to secondary systems, which can damage your underground leach field.

Which pump should I use?

To determine which pump is best for your home's sewage pumping needs, it's important to consider the amount of sewage you need to pump, your destination, and how far you need to travel to get there.

If you need to pump sewage to a pressurized sewer main, we recommend installing a grinder pump. If you are pumping water to a septic tank or gravity flow sewer main, then it is best to use a sewage jet pump.

Septic tank grinding pumps are also designed to pump thousands of feet of surface sewage, which is much further than a sewage jet pump can provide. The trade-off is that grinding pumps can only pump small amounts of sewage. Sewage ejector pumps, on the other hand, can move large volumes of raw sewage (up to 200 gallons per minute) up to 750 feet.
