What Do You Need to Size a Sump Pump?

So you’ve decided to size a pump. You might not know where to begin, in which case this brief outline will serve you.

As you’ve discovered by now, specifying the right size sump pump is vastly important. Selecting a pump that’s too powerful can result in the motor burning out, however, if your motor is too weak it can cause flooding. This is why you want to be sure you’re addressing some key areas before you begin sizing.

Here’s a checklist compiled by Zoeller to make sure you have the information needed to size your sump pump.

• • What are the electrical conditions?
    • Voltage
    • Phase
    • Cord Lengths

• • Where is this pump going to be used:
    • Residential
    • Commercial
    • Municipal
  • What are you pumping?
    • Sewage (raw unfiltered waste)
    • Effluent
    • Groundwater or Rainwater (mainly clean water free of solids)
  • How much water are you pumping? (design flow)
  • What is your static head? (or how high you are pumping)
  • How far are you pumping? (or the horizontal run of your pipe)
  • What is the diameter and type of pipe being used?
  • What fittings and how many do you have?
  • What are you pumping to?
    • Is it a gravity, septic or pressurized system?

If you have an answer for all of these questions, you are ready to find the right pump for your project.
