Submersible Sump Pump 1/2 HP

The Dayton 3BB82 is a submersible sump pump rated at 1/2 horsepower for 120V AC operation. It uses a vertical float switch with piggyback electrical connection to automate water removal in residential sump basins. The cast iron body and impeller provide durability for continuous drainage tasks. This pump suits homeowners needing reliable basement or crawlspace water management.

Flow Limits at Stated Head Heights

Performance drops as discharge head increases, a practical limit of centrifugal pump design. At 5 feet of head the pump moves 80 gallons per minute, falling to 70 gpm at 10 feet, 62 gpm at 15 feet and 50 gpm at 20 feet. Maximum shut-off head is 32 feet where flow reaches zero. Buyers needing higher flow at greater lift heights cannot meet that need with this unit.

1/2 HP Motor Determines Capacity

The 1/2 horsepower motor running at 9.8 amps on 120V AC sets the pump's maximum hydraulic output. It delivers the listed flow rates up to 32 feet of total dynamic head. Systems requiring more flow or higher pressure need a larger motor. This rating decides whether the pump matches the installation's demand.

Questions about this item

Should I choose this 1/2 HP model or a different capacity for my sump pit?

This 1/2 HP pump delivers 80 gpm at 5 ft head and 50 gpm at 20 ft head, with a maximum head of 32 ft, making it suited for typical residential sump pits requiring that flow range.

What does the 1/2 HP rating mean for actual water removal in my basement?

At 120V AC and 9.8 A, the motor moves 80 gallons per minute at 5 ft of head, 70 gpm at 10 ft, 62 gpm at 15 ft, and 50 gpm at 20 ft, so capacity drops as discharge height increases.

How does the vertical float switch work with the piggyback plug on a 120V circuit?

The vertical float switch actuates at 7 3/4 in on and 3 in off, and the piggyback plug lets you connect the pump directly to a standard 120V AC, 60 Hz outlet without separate wiring.
