About Product Overview

Meet the Superior Pump 1/2 HP 4800 GPH Cast Iron Sewage Pump with a tethered float switch—built to move wastewater quickly and reliably while withstanding tough wastewater conditions. Its cast-iron housing stands up to demanding basements, crawl spaces, and other sump applications where solids are present, delivering steady performance when you need it most.

Why this pump stands out

  • 1/2 HP motor delivers up to 4800 gallons per hour, moving wastewater efficiently even under heavy loads.
  • Cast iron housing provides rugged durability and long-term reliability in dirty water environments.
  • Tethered float switch ensures smooth, dependable on/off operation, reducing nuisance cycling and protecting the pump from burnout.
  • 2" discharge and 2" intake sized for typical residential sewage and effluent applications, with solid handling up to 2 inches in diameter.
  • 120V AC power for universal compatibility and straightforward installation.
  • Max head of 20 ft gives you flexibility to pump wastewater to a higher discharge point or through longer drain lines.
  • CSA certified for added safety and reliability.
  • Operating range from 32°F to 120°F ensures it can handle typical home wastewater temperatures without freezing or overheating.
  • Dimensions designed for sump pits with 9" width, 9.8" depth, and 16.8" height; requires a minimum sump pit diameter of 18" for proper installation.
  • Warranty—1 year limited parts and labor, backing up its durable construction and serviceability.

Use cases and ideal setups

Designed for basement and crawl space fail-safe pumping, this sewage pump expertly handles graywater and solid-laden effluent where household waste needs timely transfer to the sewer line or septic system. It’s well-suited for:

  • Basement sump pits where groundwater carries solids or debris that must be moved away quickly.
  • Home utility rooms or laundry areas where wastewater may contain lint, hair, or rags up to 2" in diameter.
  • Projects requiring reliable head height to reach a central drain or septic line from a lower-vault installation.

How it works and key capabilities

When water rises to the 14" turn-on level, the tethered float activates the motor, starting the pump. As water drops to the 6" level, the float disengages, stopping the pump to minimize wear and save energy. The unit’s 20 ft maximum head means it can push effluent through longer discharge runs or to elevated drainage points without compromising performance. The 2" discharge port ensures compatibility with standard drain piping, while the 2" intake accommodates typical household wastewater flows with solids present.

Installation and practical tips

For reliable operation, ensure your sump pit meets the minimum diameter requirement (18"). The pump’s compact footprint and cast-iron construction make it a strong, long-lasting choice in pits that face sediment and debris. Plan for a check valve or backflow prevention in the discharge line to prevent reverse flow, and verify electrical supply is 120V with a dedicated circuit if possible. Routine maintenance—occasional cleanout of the intake area and inspection of the power cord and switch—keeps performance steady year after year.

Maintenance and care

To extend the life of your sewage pump, perform these simple steps:

  • Regularly remove debris from the sump and intake area to prevent clogging.
  • Inspect the tethered float and wiring for signs of wear or corrosion; replace if needed.
  • Test cycling every few months to confirm proper on/off operation and that the float reaches full travel.
  • Schedule periodic checks of the discharge line for obstructions and ensure the 2" discharge remains clear.
