Unfortunately, it’s a myth that grinder pumps can’t clog. So if a grinder pump has more torque and chops up everything that comes its way, using one for every job seems like an easy decision to make.īut there are a number of reasons to stick to a sewage pump when the job calls for it, and not just because of the potentially higher energy costs of grinder pumps. However, just as with normal sewage pumps, they can last for years if well maintained.

In general, they cost a bit more than regular sewage pumps and sometimes use more electricity. Grinder pumps are more powerful, starting at 1 hp. The slurry can then more easily pass through lines with smaller diameters than solid waste could, so the discharge line and pump connection is usually 2” or less, and some use 1.25”. In addition to having an impeller, grinder pumps use cutter blades to pulverize, or grind, solids. Residential sewage grinder pumps handle a lower volume of waste-between 35 and 70 gallons per minute-but over much longer distances, into the several thousands of feet. Grinder pumps are a type of sewage pump, which can explain why people sometimes use both terms interchangeably. But what about that other 10% of the time? What’s a grinder pump? Nine times out of 10, a regular sewage pump that doesn’t grind is what you’ll need for a residential plumbing job. And because what goes in the septic pump must fit through the pipes “as is,” sewage pumps have larger diameters for discharge line and pump connection: between 1.5” to 3”. A sewage ejector pump with 1/2 hp is all that’s typically needed for a residential home. Sump and sewage pumps usually have lower horsepower (hp) than grinder pumps. A typical sewage pump will use a vortex-style impeller to prevent clogging and efficiently move the liquid. Each type of impeller and its dimensions correspond with different head pressures. There are three general types of impellers: vortex, semi-open and enclosed channel. Also called sewage ejector pumps, some can move up to 200 gallons a minute of waste horizontally as far as 750 feet.Ī sewage pump uses an impeller to provide the head pressure that moves the waste vertically.

Unlike effluent or sump pumps, which should be used only to remove clear or gray water, sewage pumps are designed to move “dirty” or sewage waste to a septic tank, gravity flow sewer main or leach field.

Whether you’re replacing or installing new, discover how to choose the best residential sewage or grinder pump for the job. While the terms are sometimes used interchangeably, understanding the difference between sewage and grinder pumps is important to get the job done right the first time. If you're working on a replacement sewage pump, it can seem as simple as looking at the model number and ordering a new pump, but what if installing the wrong one the first time led to the problems? And if you’re plumbing new construction, making the right choice means the homeowner will be satisfied with your work for years to come.
