Goulds WW0511A Sewage Pump 1/2 Hp 115V Piggyback Float

Product Description

The GOULDS WW0511A is a 1/2 horsepower, 115-volt sewage pump designed for residential and light commercial wastewater removal applications. Built to handle raw sewage and effluent containing solids, this pump is configured with a piggyback float switch that allows the unit to operate automatically based on basin water level. At 1/2 HP, the pump delivers reliable lifting capacity suited for standard below-grade sewage ejector systems. Licensed plumbers and mechanical contractors install this pump in pit configurations where gravity drainage to a municipal sewer or septic system is not possible.

The WW0511A is suited for residential sewage ejector installations, including basement bathrooms, laundry rooms, and utility areas that drain below the main sewer line. The included piggyback float switch connects between the pump cord and power outlet, enabling automatic on/off cycling without a separate control panel. This makes the unit straightforward to wire and commission in a standard sewage basin setup.

Key Features

• 1/2 HP motor rated for 115-volt single-phase operation
• Piggyback float switch included for automatic level-based control
• Designed for sewage and effluent service with solids-handling capability
• Piggyback cord configuration allows manual override by bypassing the float switch
• Suitable for standard residential sewage ejector basin installations

Compatibility

Designed as an OEM-style replacement or direct installation sewage pump for residential and light commercial below-grade ejector basin systems requiring a 115-volt, 1/2 HP pump with integrated float switching.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Disconnect power at the circuit breaker before servicing or replacing any sewage pump. Ensure the basin cover is properly sealed after installation to contain gases and meet code requirements. Do not run the pump dry, and confirm float switch travel is unobstructed within the basin before restoring power.
