Prostormer 3500 GPH 1HP Submersible Sump Pump with Built-in Float Switch – Clean/Dirty Water for Pool, Pond, Basement

Overview

Meet the Prostormer sump pump, a robust 1HP unit engineered to move heavy water with confidence. With a maximum flow of 3500 GPH, it can clear basements, pools, ponds, and irrigation runoff faster than smaller pumps while staying compact enough for tight spaces. The built-in float switch powers pumping on and off automatically, helping you monitor water levels without constant supervision.

In real life, this submersible design shines when you face sudden cellar floods after heavy rain, or persistent water in a garden shed. The thermoplastic housing resists corrosion in damp environments, and a durable base plate minimizes debris collection in the sump pit, keeping things cleaner between uses.

• 1HP power delivers strong performance for draining tasks, outperforming typical 3/4HP options.
• Max 3500 GPH moves water quickly to reduce downtime and speed up cleanup.

Flexible connections & controls

Three outlet sizes let you adapt to different hoses and flow needs: 1 inch, 1-1/4 inch, and 1-1/2 inch. You can also choose manual mode for continuous pumping or automated mode for level-triggered operation. In auto mode, the pump starts when water rises and stops at the set low level.

• Three outlet sizes accommodate a range of hoses and applications.
• Manual mode lets you run the pump even when water is low; auto mode saves power by responding to water level.

Care and safety

To maximize service life, follow the included tips: ensure the unit is fully submerged and held at a slight angle during startup to expel trapped air. Do not rely on it as a continuous circulation pump, and flush the impeller after use to prevent debris buildup. The sealing structure and thermoplastic body resist corrosion, and the higher base plate helps prevent debris from accumulating in the sump.
