Purchasing a sewage pump requires careful consideration to ensure efficient and reliable operation. Here are nine key factors to evaluate when choosing a sewage pump: Flow Rate: The flow rate indicates the amount of water the pump can discharge per hour. Choose one that matches your specific needs, such as 5-10 m³/h for a standard home setup with minimal plumbing. Larger homes or those with additional appliances like washing machines might need a pump with higher flow rates. Installing a dual-pump system can also be beneficial in certain situations.
