½ hp 115 V Sink Drain Pump System

This Dayton 12F740 system combines a half-horsepower pump with a six-gallon HDPE basin for automatic grey-water removal. The cast-iron pump body and stainless-steel impeller are actuated by a vertical float switch with a piggyback electrical connection. Rated at 115 V AC and 4.9 amps, it delivers 42 gallons per minute at five feet of head. The unit includes ten feet of power cord for flexible placement.

Suitable applications and limits

Designed for basement sinks, laundry trays or bar sinks where gravity drainage is unavailable. The 1½-inch inlet, outlet and vent connections suit standard residential DWV piping. Not suited for raw sewage or solids larger than the impeller can pass. Installations requiring higher flow at greater head or a larger basin capacity should consider a different system.

Deciding specification — flow at 10 ft head

At ten feet of head the pump moves 38 gallons per minute, which determines whether it can handle the fixture load and vertical lift in your installation. Match this figure against the total dynamic head calculated from your pipe run and elevation change. If the required flow exceeds 38 gpm at that head, a higher-capacity pump is needed.

Questions about this item

How do I choose between the available flow-rate ratings for this pump?

The system delivers 42 gpm at 5 ft of head, 38 gpm at 10 ft, 32 gpm at 15 ft and 24 gpm at 20 ft; match the rating to the vertical lift your installation requires.

What does the half-horsepower motor mean for actual drainage performance?

The 0.5 hp motor drives a cast-iron pump with a stainless-steel impeller to move up to 42 gallons per minute at low head, suitable for typical sink and floor-drain applications.

How does the 115 VAC supply and piggyback float switch limit installation options?

The unit plugs into a standard 115 V AC outlet drawing 4.9 amps, and the piggyback float switch connects inline so the pump cord plugs into the switch, which then plugs into the wall.
