Buying Guide
- What is your primary drainage task? Choose higher GPH and greater head for fast basement drain or pool/water feature drainage.
- What solids will you handle? Look for a pump with a bottom or side strainer that tolerates debris up to 1/5 inch to prevent clogging.
- What discharge size do you need? Most 1 HP pumps use 1″ to 1-1/4″ discharge; verify compatibility with your hoses and adapters.
- How long should the cord be? Longer cords offer flexible placement but require safe storage and strain relief considerations.
- Durability matters: metal housings last longer in harsh environments; thermoplastic is lighter and corrosion-resistant but may be less sturdy.
- Safety features: thermal overload protection and dry-run prevention extend pump life and reduce risk of damage.
