Goulds EP0511AC Effluent Pump 1/2 Hp 115V Float Switch

Product Description

The GOULDS EP0511AC is a 1/2 horsepower effluent pump rated at 115 volts, designed to move treated wastewater from septic tanks, dosing chambers, and holding tanks to a drain field or secondary treatment system. Supplied with a piggyback float switch for automatic on/off level control, this unit eliminates the need for a separate switch installation. Licensed plumbers and septic system contractors are the primary installers. The pump is built for continuous submersible service in residential effluent applications where solid content is low and flow reliability is critical.

The EP0511AC is suited for residential and light commercial effluent disposal systems, including mound systems, drip irrigation fields, and pressure-dosed septic systems. The piggyback float switch connection allows the float to be bypassed when manual operation or system testing is needed, which simplifies startup and service calls. This pump is a direct fit for new installations and replacement service in standard effluent pump basins.

Key Features

• 1/2 HP motor rated at 115 volts for standard residential single-phase power
• Piggyback float switch included for automatic water-level-based operation
• Piggyback plug design allows float bypass for manual run without rewiring
• Submersible construction rated for continuous effluent service
• Designed for low-solids wastewater typical of septic effluent applications

Compatibility

Designed as an OEM-style replacement or new-installation effluent pump for residential submersible effluent pump basins and septic dosing systems requiring a 115-volt, 1/2 HP submersible pump with integrated float switch control.

Installation Notes

Installation should be performed by a licensed plumber or septic system contractor in accordance with local plumbing codes and IFGC or state on-site sewage regulations. Disconnect and lock out power at the panel before lowering or removing the pump from the basin. Verify basin diameter accommodates the float switch swing radius before installation. Never run the pump dry, as this will damage the motor seal.
