Vertical Float Design

Vertical float activates faster than horizontal floats in tight crawl space basins—solid polypropylene won't waterlog, ensuring reliable automatic operation.

Cast Iron Durability

Professional-grade cast iron construction in switch case, motor housing, and pump housing delivers long-lasting performance in demanding crawl space conditions.

Compact for Small Basins

Robust design fits smaller sump basins common in crawl spaces—sturdy base prevents debris clogs and keeps pump stable during operation.

Factory Tested

Every pump tested to published performance curve before shipping—backed by 3-year manufacturer warranty for peace of mind and proven reliability.
