1/3 HP Submersible Sump Pump

The Dayton 3BB70 is a 1/3 HP submersible sump pump designed for residential water removal. It operates on 120V AC power at 60 Hz and draws 5.8 amps during operation. A vertical float switch with piggyback electrical connection provides automatic level control. The pump body and impeller are constructed from cast iron for durability.

Vertical Float Switch and Discharge

The pump activates at a 7 1/4 inch water level and shuts off at 3 inches, requiring a sump basin deep enough to accommodate this range. A 1-1/2 inch female discharge outlet connects to standard plumbing fittings. The carbon ceramic shaft seal helps prevent leakage around the motor shaft. Maximum head capacity reaches 30 feet for vertical lift applications.

Suited for Standard Residential Basements

This unit suits homeowners needing automatic water removal in typical basement sump pits with 120V power available. The 9 1/8 inch body diameter fits common basin sizes. Buyers needing higher flow rates at 20 feet of head or greater maximum lift should look at larger capacity models. Those without a grounded 120V outlet near the sump location cannot use this pump.
