Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Guard your basement with the Wayne 1/3 HP Sump Pump, a reliable, automatic solution designed for everyday dampness and heavy rain scenarios. This model pairs a compact thermoplastic housing with a tethered float switch, delivering powerful water removal without complicated setup or frequent maintenance. With a 3,000 GPH maximum discharge and a 1-1/2" outlet, it’s a practical choice for sump pits of modest size that still demand serious capacity.

  • Power and performance: 1/3 HP motor operating on 120 V AC provides steady, dependable pumping, up to 3,000 gallons per hour for efficient flood protection.
  • Head geometry for real-world basements: At 10 ft of head, you can expect about 2,130 GPH; at 20 ft, the flow drops to around 400 GPH, giving you transparent expectations for longer discharge runs.
  • Discharge and intake design: 1-1/2" discharge with top suction intake helps minimize debris clogging and keep debris out of the pump mechanism.
  • Construction and durability: Thermoplastic housing blends lightweight handling with corrosion resistance in humid, damp environments.
  • Automatic operation: Tethered float switch detects rising water levels and triggers pump activation without manual intervention.
  • Safety and compliance: CSA and UL listed for peace of mind in residential settings.
  • Practical dimensions and wiring: Compact 11-inch height fits into tight sump pits, with an 8-foot power cord to reach outlets without extensions.

Ideal usage scenarios

Designed for basements, crawlspaces, garages, and utility rooms that experience seasonal flooding or routine water accumulation. It handles caught rainwater, sump drainage, and meltwater from snow with ease, helping to keep floors dry and assets protected. Its top suction inlet reduces the chance of debris overpowering the pump, while the tethered float ensures a reliable on/off cycle even as water levels fluctuate.

Why this Wayne sump pump stands out

Compared to metal-bodied alternatives, the thermoplastic construction resists rust and corrosion in consistently damp environments, extending service life with less maintenance. The combination of a robust 1/3 HP motor, a high-flow capacity, and a practical discharge height makes it a versatile choice for homeowners who want strong performance without overkill. The 8-foot cord length adds installation flexibility, so you can position the pump for optimal drainage without compromising safety or reach.

Installation and maintenance tips

  • Install the pump in a sump basin with a secure, clean outlet line to a safe exterior drainage path.
  • Keep the top suction intake free of debris; periodically check and clean the strainer to maintain maximum flow.
  • Ensure the float has unfettered movement and isn’t obstructed by the sump lid or stored items in the basin.
  • During cold months, protect the area from freezing temperatures to prevent ice blockage and potential damage.
  • Regularly inspect electrical connections and test the auto-start/stop function to confirm reliable operation before heavy rainfall seasons.

With the Wayne 1/3 HP 3,000 GPH Sump Pump, you get a practical, automatic solution that blends solid performance with dependable, straightforward operation. It’s a smart choice for homeowners who want effective flood defense, clear value, and long-term reliability in a compact, user-friendly package.
