Sink Pump System 1/3 HP 115V

The Dayton 12F739 Sink Pump System is a complete unit designed to move wastewater from sinks and fixtures located below the main drain line. It serves residential and light commercial installations where gravity drainage is not possible. The system includes a pump, basin, and vertical float switch assembled for straightforward installation. It operates on standard 115V AC power drawing 4.1 amps.

Thermoplastic Pump with 6 Gallon HDPE Basin

The pump body and impeller are constructed from thermoplastic and plastic for corrosion resistance. The high-density polyethylene basin holds 6 gallons and stands 13 3/8 inches tall. It accepts incoming waste through a 1 1/2 inch inlet and discharges through a matching 1 1/2 inch outlet. A 1 1/2 inch vent connection allows proper air flow. The piggyback plug on the float switch enables simple electrical hookup without hardwiring.

Flow Rates at 5 to 20 Feet of Head

The pump delivers 40 gallons per minute at 5 feet of head and 36 gallons per minute at 10 feet of head. Output decreases to 32 gallons per minute at 15 feet of head and 23 gallons per minute at 20 feet of head. These figures represent steady-state performance under continuous lifting conditions. The vertical float switch actuates automatically to maintain basin level during sustained use.

Questions about this item

How long can the 1/3 HP motor run continuously before thermal protection trips?

The pump draws 4.1 A at 115 V AC; continuous operation is limited by the motor's internal thermal overload, which resets automatically once the windings cool.

What sound level and heat output should I expect when the pump cycles all day in a 6 gal basin?

The thermoplastic body and plastic impeller run quietly; motor heat is dissipated into the pumped fluid, keeping the basin area only slightly warm during frequent cycles.

Which fittings and pipe sizes must I already have to connect the 1 1/2 in inlet, outlet and vent?

You need 1 1/2 in slip or threaded PVC fittings for the basin inlet, discharge outlet and vent connection, plus a check valve on the discharge line.
