Prostormer 1HP Sump Pump - 3700 GPH Submersible with Auto Float Switch (Orange)

Overview

Meet the Prostormer 1HP sump pump, a compact submersible unit designed to move up to 3700 GPH. Built for versatility, it works with clean or mixed water in spaces from flooded basements to pool and pond maintenance, as well as irrigation tasks. The orange housing helps it stand out in a sump pit or outdoor setup.

Power, performance, and smart operation

The system relies on an automatic float switch to start and stop as water level changes. For low-water scenarios, you can lock the switch to keep pumping continuously. Before first use, fully submerge the unit and tilt it underwater for 20–30 seconds to expel trapped air.

• 1 HP power delivers rapid drainage for time-sensitive jobs.
• Maximum flow up to 3700 GPH accelerates water removal.
• Three outlet sizes (1", 1-1/4", 1-1/2") fit a range of hoses and flow needs.

Durability and design for lasting use

The pump features a corrosion-resistant thermoplastic body and a raised base plate to prevent debris buildup in sump pits. A sealed construction helps it endure damp environments and outdoor use while remaining relatively lightweight for handling.

• Durable thermoplastic housing resists moisture and corrosion.
• Open mode enables continuous pumping when needed; power off to stop.
• Automatic ON/OFF control activates with water rise and deactivates when water is removed.

Real-world uses and setup tips

Common scenarios include clearing basement floods, draining pools or ponds, refilling garden irrigation reservoirs, and performing aquarium maintenance. In practice, you might quickly empty a soggy cellar after a storm or prepare a pond for cleaning and refilling. This model is designed for straightforward setup with hose connections that match your existing gear.

What you get and tips for setup

• 1 HP sump pump with up to 3700 GPH capacity.
• Three outlet options to fit standard hoses.
