Buyer’s Guide: What to Consider

Consider these key factors when choosing a septic aerator pump to ensure it meets your system’s requirements and lasts for years.

• Air Output: Measured in liters per minute or GPH. Match the pump's output to your septic system's size for effective aeration.
• Rebuildability: Some pumps can be rebuilt, extending their life and reducing long-term costs. Check if replacement parts are available.
• Noise Level: Linear diaphragm pumps are generally quieter than piston types. Look for models with denoising features if noise is a concern.
• Alarm Compatibility: A built-in or external alarm alerts you to pressure drops, helping prevent system failure. Decide if this feature is important for you.
• Weatherproofing: Ensure the pump is UL rated for outdoor use if installed outside. Weatherproof construction protects against rain and temperature extremes.
