A sewage ejector pump is far superior to a sewage ejector pump when pumping to a septic tank or a gravity flow sewer line. If you need to pump sewage to a pressurised sewer main, we propose installing a grinder pump. Which pump to choose: grinder pump vs sewage pumpĬonsider the volume of sewage you need to pump, its destination, and how far it has to travel to get there when determining which pump is best for your home's sewage pumping needs. This means it won't be transferred to the secondary system, which could destroy your subsurface leach field. It is then carried to the pressurised sewer main from there.īecause the slurry is so finely ground, it will not separate from the liquid once inside the septic tank, septic grinder pumps should not be used with septic tank systems. A septic grinder pump can assist you transport sewage from your septic tank to your pressurised sewer main.īlades inside the septic grinder pump are used to crush raw sewage into slurry before it is discharged. This means that they are better suited than sewage ejector pumps for transporting modest amounts of raw sewage over longer distances. Septic grinder pumps are low-volume, high-pressure systems. It has a smaller exit, which is one of the most important features of a grinder. It chews things up because it doesn't have to pass solids. On a typical grinder pump, this discharge will be around one inch and a quarter. It will grind it into a slurry, which will then be pumped out in a reduced quantity. Everything that is sucked into the pump will be chopped up by it. It functions similarly to a powerful garbage disposal. Septic Grinder Pumpsĭue to the cutter wheel, grinder pumps are larger, heavier, and more powerful than sewage pumps. The two-inch discharge is a fundamental element of the sewage pump. Sewage ejector pumps, in general, are designed to handle large volumes of sewage at low pressure. This is substantially more than what septic grinder systems can pump. Sewage ejector pumps, on the other hand, are designed to transfer up to 200 gallons of raw sewage per minute. As a result, they can only pump to distances of less than 750 feet. Raw sewage from your home is pumped into a septic tank or gravity flow sewer main by sewage ejector pumps. The sewage is subsequently forced into the discharge pipe using pressure. Instead, raw sewage is moved through the bottom of the pump using impellers that spin. For example, unlike grinder pumps, sewage ejector pumps do not have grinding blades. Septic grinder pumps and sewage ejector pump systems both pump raw sewage from your home to a separate location, but they do it in different ways.

Learn how to choose the best home sewage or grinder pump for the job, whether you're replacing or installing new. If you're looking for a new sewage pump, it may appear as simple as checking up the model number and ordering one, but what if you installed the wrong one the first time?Īlthough the names are frequently interchanged, knowing the distinction between sewage and grinder pumps is critical for getting the job done correctly the first time. Gravity alone won't be able to transfer the wastewater in a bathroom below the sewer lines, so you'll need to choose between a sewage or grinder pump. It's not uncommon for someone to request a grinder pump when all they truly need is a sewage pump. They have a lot in common, but they're made for different purposes. Many people mix up Sewage Pumps with Grinder Pumps.
