Goulds EP0411A Effluent Pump 0.4 Hp 115V Float Switch

Product Description

The GOULDS EP0411A is a 4/10 horsepower effluent pump designed to move treated wastewater from septic tanks, holding tanks, and dosing chambers to drain fields or other downstream discharge points. Operating on 115 volts, this pump ships with a piggyback float switch that automates on/off cycling based on liquid level, eliminating the need for a separate control device. The piggyback plug design allows the float switch to be bypassed for manual operation during testing or service. Licensed plumbers and septic system installers are the primary trades that handle this equipment.

The EP0411A is suited for residential and light commercial effluent applications where solids content is low and relatively clear wastewater needs to be moved reliably on a timed or demand basis. Typical installations include secondary treatment systems, mound systems, and pressure-dosed drain fields where an automatic pump-and-float assembly is required by local health department or building code. This pump is not intended for raw sewage or high-solids slurries.

Key Features

• 4/10 HP motor rated for 115-volt single-phase power
• Piggyback float switch included for automatic level-based operation
• Piggyback plug allows float bypass for manual or test mode without rewiring
• Designed for effluent service with low solids content
• Compact submersible design suited for residential septic dosing chambers

Compatibility

Designed as an OEM-style replacement or direct installation unit for residential effluent pump applications in septic dosing chambers and holding tanks requiring a 115-volt submersible pump with integral float control.

Installation Notes

Installation should be performed by a licensed plumber or septic system contractor in accordance with local health department requirements and applicable plumbing codes. Disconnect and lock out power at the circuit breaker before lowering or removing the pump from the basin. Verify basin depth and float tether length to ensure the switch activates and deactivates at the correct levels before returning the system to service. Never run the pump dry, as motor damage from cavitation or overheating will occur without liquid present.
