1/2 HP Submersible Sump Pump

The Dayton 3YU75 is a 1/2 horsepower submersible sump pump designed to remove water from residential sump pits. It operates on 115V AC power at 60 Hz and draws 4.1 amps during operation. A tether float switch with piggyback electrical connection provides automatic on and off control based on water level.

Switch points and pit requirements

The pump activates at a 15 inch on point and shuts off at an 8 5/16 inch off point, requiring a sump pit diameter of at least 12 inches to accommodate the tether float travel. Stainless steel body and impeller construction resists corrosion in typical sump environments. Buyers needing a vertical float switch for narrower pits or a different voltage should look at alternative models.

Flow rates at measured head

At 5 feet of head the pump delivers 34 gallons per minute, decreasing to 25 gpm at 10 feet, 15 gpm at 15 feet and 7 gpm at 20 feet, with a maximum shut-off head of 23 feet. These figures determine whether the unit can meet the required discharge capacity for a specific installation.

Questions about this item

How do I install the tether float switch on this Dayton 3YU75 sump pump, and what step do people often miss?

Mount the pump in a pit at least 12 inches wide, connect the 1-1/4 inch discharge, then plug the piggyback tether float into a 115V AC outlet and the pump into the float. The step often missed is setting the tether length so the float travels freely between the 8 5/16 inch off point and 15 inch on point without catching on the pit wall.

What maintenance or replacement will the Dayton 3YU75 need over time?

The Buna-N shaft seal and stainless-steel impeller are the main wear items. Inspect the seal annually for leaks and clean debris from the impeller; replace the seal if water reaches the motor housing. The tether float switch may also need replacement if the contacts corrode or the tether frays.

What is the first limit that appears when the Dayton 3YU75 runs continuously under load?

The maximum head of 23 feet is the first hard limit. Beyond that the pump cannot lift water, flow drops to zero, and the motor runs at 4.1 amps without moving fluid, which can overheat the windings. Flow also falls sharply — 34 gpm at 5 feet of head versus 7 gpm at 20 feet — so sustained high-head operation is the practical constraint.
