Key features that matter in real-world use
-
Powerful yet compact — 1/2 HP motor delivers up to 4,300 gallons per hour, making quick work of rising water in typical sump pits.
-
Efficient performance under pressure — Discharge flow at 10 ft is 3,360 GPH and at 20 ft drops to 1,260 GPH, so you’ll have meaningful pumping capacity even with greater vertical lift.
-
Smart, automatic control — Vertical float switch provides reliable, hands-off operation. Turn-on at 9 inches and turn-off at 4 inches help prevent nuisance cycling and ensure water is removed promptly as levels rise and fall.
-
Rugged, practical design — Thermoplastic housing resists corrosion from wet environments, while top suction intake helps minimize clogging from debris commonly found in sump pits.
-
Standard compatibility — 1-1/2 inch discharge outlet and 8 ft cord provide flexible installation options to fit common sump configurations.
-
Safe, compliant operation — UL-listed for reliability and safety, designed for AC power (120V) use in basements, garages, or utility rooms.

Operational range — Effective in temperatures from 40°F to 110°F, suitable for a variety of climates and wet environments.
Why this Wayne sump pump stands out
The Wayne 1/2 HP model combines a lightweight thermoplastic body with a robust vertical float switch system, offering dependable auto-operation without the heavier maintenance concerns of some metal pumps. Its variable discharge performance across different heads means you get practical pumping power whether your pit is shallow or deep, without oversizing your setup. The top-suction intake minimizes air locks and debris accumulation, helping maintain steady flow even when sump pits aren’t perfectly clean. And with UL compliance, you have an added layer of assurance for household and light commercial use.
Ideal use cases
- Basement and crawl-space flooding prevention in homes and small commercial spaces
- Storm water and sump pit drainage where quick water removal is essential
- Garage or workshop dewatering after rain or snowmelt
- Temporary dewatering during construction or renovation projects
Practical tips for installation and maintenance
- Place the pump in a sump pit with adequate clearance to allow the vertical float to move freely from 9 inches (on) to 4 inches (off).
- Use the 1-1/2 inch discharge outlet with compatible fittings to ensure a smooth, reliable outlet flow.
- Keep the top suction intake free of large debris to maintain consistent performance; periodic cleaning reduces the risk of clogs.
- Ensure the pump is powered by a proper 120V AC supply and kept away from standing water that exceeds its 110°F maximum operating temperature rating.
- Check the 8 ft power cord for any wear or damage during routine maintenance and replace promptly if signs of deterioration appear.
With the Wayne 1/2 HP 4,300 GPH Thermoplastic Vertical Float Switch AC Submersible Sump Pump, you get a purpose-built solution that combines practical power, automatic control, and dependable reliability—designed to protect living spaces from water intrusion today and for years to come.
