Which Zoeller pump do I need?

Zoeller is one of the leading brands of submersible pumps for dewatering (sump) or effluent (septic tank systems). They are popular due to their great pricing, reliability and warranty. 

To order a model, you need to know two things:

  1. How many gallons per minute you would like to pump
  2. Total height, also called rise, that the water must go
