Buying Guide
Key considerations
When selecting a 3/4 HP sump pump, consider horsepower and flow rate (GPH) to match your drainage needs. A higher GPH helps manage heavy rain or rapid groundwater influx, but ensure the head height (how high the water must be lifted) aligns with your pit and discharge setup. Discharge size matters; many units use 2″ NPT, which is common for basement drains, while some offer 1-1/2″ options. Material matters: cast iron and stainless steel offer durability in damp environments, while thermoplastic options reduce weight. Automatic versus manual operation matters for convenience; many models include piggy‑back floats for easy mode switching. Debris handling, ease of installation, and warranty are practical considerations for long‑term use.
