MID-SUCTION OVER BOTTOM-SUCTION DESIGN
The WE20G05P4-21’s mid-suction design is a key advantage for aerobic septic systems. By positioning the intake in the middle of the pump, it prevents debris from clogging the intake screen, as solids settle at the bottom of the pump tank. This reduces maintenance needs and extends pump life compared to bottom-suction models like the Franklin C1 Series or Sta-Rite Dominator, which can be more prone to clogging in systems with residual particles.
