1/4 HP Submersible Sump Pump

The Dayton 3YU57 is a 1/4 horsepower submersible sump pump designed for residential drainage. It operates on 115V AC at 60 Hz and draws 2.3 amps. The pump body is polypropylene with a polyamide impeller and a carbon ceramic shaft seal. A vertical float switch controls automatic operation.

Suitable for standard sump pits

This pump suits homeowners needing automatic water removal from pits at least 10 inches in diameter. The vertical float requires sufficient clearance to move freely without obstruction. Buyers with narrow pits or limited vertical space should look at alternative switch designs. The maximum head of 21 feet limits use in high-lift applications.

Simple drop-in installation

Lower the pump into the pit, connect the 1-1/4 inch discharge, and plug the integral cord into a grounded outlet. The float activates at 4 29/32 inches and shuts off at 1 49/64 inches. Debris can jam the float, so keep the pit clean and test the switch travel after installation.
