Buying advice

When choosing a sewage effluent pump, consider the total dynamic head, solids handling capacity, and whether a backup system is needed. Cast iron pumps offer durability for long-term use, while vortex impellers reduce clogging. Ensure the pump is properly rated for your application (e.g., septic effluent vs. sewage) and check the warranty. Installation by a professional is recommended for safety and code compliance.
