    Tips: Sewage Pump vs. Grinder Pump

    Sewage pumps are able to handle some solids-handling capability, but only to a certain extent. This type of pump is commonly used with basement toilets to pump the sewage up into the sewer lines for the home or utility with the solids still intact, or if a home is located in a low area and sewage must be pumped uphill into the sewer or septic system.

    Grinder pumps are a subtype of sewage pumps. Generally speaking, sewage pumps that are not grinder pumps can move sewage solids up to two inches in diameter that are easy to break down or dissolve. Harder material will cause clogs and significant wear and tear on the pump. However, a general sewage pump that is not a grinder pump is usually less expensive and draws less power. This also means that the pump is not able to move sewage to as high of a point as a grinder pump can.

    Better than I expected
    I bought this 3 hp submersible sewage pump a month ago and it worked very well. And there's no noise when the sewage pump is running. I will recommend to my friends!

    Perfect replacement
    Installed in less than an hour and it has worked as designed. It was an identical replacement of my old sewage pump. I only swapped the direction of the switch from right side hang to left side hang due to the 3 hp submersible sewage pump in the sewage tank. Easily done by removing a single screw.
