Product and Purpose

The Dayton 3YU66 is a 1/4 HP submersible sump pump designed for residential water removal. It operates on 115V AC power at 60 Hz and draws 2.6 amps during use. The unit suits homeowners needing automatic drainage in a sump pit of at least 12 inches diameter.

Thermals Noise and Power

The pump runs on standard household current with a 2.6 amp draw at 115 volts. Its polypropylene body and carbon ceramic shaft seal are built for continuous submersion in cool water. The tether float switch activates the motor at 11 1/2 inches and shuts it off at 6 inches to manage cycle frequency.

Flow and Head Performance

At 5 feet of head the pump delivers 16 gallons per minute, at 10 feet it provides 11 gpm, and at 15 feet it moves 6 gpm. Maximum shut-off head reaches 20 feet. Buyers needing higher flow rates at greater lift heights should verify these figures against their system requirements.

Questions about this item

How do I install the 3YU66 pump and set the tether float so it does not short-cycle?

Place the pump in a pit at least 12 inches wide, secure the 1-1/4 inch discharge, and adjust the tether length so the float travels freely between the 6 inch off point and the 11-1/2 inch on point without catching on the pit wall.

Which parts of the 3YU66 will need replacement after extended use?

The carbon and ceramic shaft seal and the polyamide impeller are the primary wear items; the polypropylene body and tether float mechanism typically last the life of the pump.

At what head height does the 3YU66 flow drop below 10 gallons per minute?

Flow falls to 11 gpm at 10 feet of head and 6 gpm at 15 feet; maximum shut-off head is 20 feet.
