Sink Pump System 1/2 HP 115V

The Dayton 12F741 is a complete sink drain pump system designed for residential or light commercial drainage where gravity flow is not possible. It includes a 6 gal HDPE basin, a 1/2 hp thermoplastic pump body, and a stainless steel impeller. The unit operates on 115V AC drawing 4.9 A and uses a vertical float switch with piggyback electrical connection for automatic operation.

Flow rates across head pressures

Under sustained load the pump delivers 55 gpm at 5 ft of head, 51 gpm at 10 ft, 46 gpm at 15 ft, and 39 gpm at 20 ft of head. These figures show how capacity declines as discharge height increases, allowing installers to match the system to the actual vertical lift required. The thermoplastic construction and stainless steel impeller resist corrosion during continuous or intermittent cycling.

6 gal basin capacity

The 6 gal HDPE basin with a 13 3/8 in height and 1 1/2 in inlet, outlet, and vent diameters determines whether this system fits the available space and connects to existing piping. Buyers needing a larger holding volume or different port sizes will need an alternative solution.

Questions about this item

How much electricity does the 1/2 HP motor draw on 115V AC?

The pump is rated at 4.9 A on 115V AC, which determines its operating power draw.

What plumbing connections must already be in place for the 1 1/2 in inlet, outlet and vent?

The basin accepts a 1 1/2 in inlet, a 1 1/2 in discharge and a 1 1/2 in vent, so matching piping and fittings are required.

Will the 6 gal HDPE basin and vertical float switch clear an existing 13 3/8 in deep sump pit?

The basin height is 13 3/8 in, so the pit must provide at least that much vertical clearance for the float to operate freely.
