Sewage Pump Buyers Guide

Picking the right grinder pump for your home can be difficult. Many factors can affect which is the right model. If you are unsure of which pump to buy we recommend reviewing the following factors before making a purchase:

  • Head height – Every home will have a slightly different head height. It is important to get a pump powerful enough to lift the water up from the basin and out of your home. The deeper the basement the more power sump pumps are necessary
  • Max flow rate – Flow rate and max GPM are two important factors to consider. The more water sewage pumps have to drain means a larger horsepower motor
  • Ability to grind solids – Even the best ejector pumps are worthless if they can’t shred and grind small solids so they can pass through sewage lines into the city drains or septic system. We recommend sewage ejector pumps with a vortex impeller for the best results
  • Pump body material – A submersible sewage pump will take a lot of wear and tear, that is why the body material is important.
  • Pump accessories – All of the pumps on this list can drain water out your sewage line, but they all don’t come with the same features and add ons. We recommended installing separate battery backups and pump failure alarms in case the power goes out in a big storm.
