Choose 218 1/3 HP Hydromatic Heavy Sump Pump (10ft) If:

  • You need 2,100 GPH flow capacity at 10' dynamic head.
  • Your sump pit accommodates a 12" clearance footprint.
  • You favor the Vertical Float Switch actuation design.

Hydraulic Performance & Head Sizing

When operating at 10 feet of Total Dynamic Head, the Zoeller 53-0001 delivers 1,440 GPH versus 2,100 GPH for the Pentair Myers 218-10FT. Pumping capacity curves indicate that both models handle standard residential foundation drainage effortlessly.

Switch Technology & Pit Clearance

The Zoeller employs a Vertical Mechanical Float requiring a 15" pit, whereas the Pentair Myers utilizes a Vertical Float Switch suited for basins with at least 12" clearance. Ensuring your pit allows uninhibited float movement is essential to preventing switch hang-ups.
