What is a key specification for pump tanks?

1. Submersible and wastewater approved

2. Must be lightweight

3. Should be manual

4. Only for potable water

The correct answer is: Submersible and wastewater approved

A key specification for pump tanks is that they need to be submersible and wastewater approved. This is crucial because pump tanks are typically used to handle wastewater and are designed to operate underwater, ensuring that the pump can effectively manage the flow out of the tank without causing damage to the system or posing a risk of contamination. The submersible aspect refers to the construction of the pump itself, which must be able to operate when submerged in the fluid, usually in a septic or wastewater application. Wastewater approved indicates that the materials and design are suitable for handling sewage and other types of wastewater without degrading or failing. Other options do not emphasize the necessary capabilities for dealing with wastewater management. For instance, while it may be beneficial for a pump tank to be lightweight for easier installation, it is not a key specification that ensures effectiveness in its primary function. Similarly, requiring a manual operation is less common; most modern systems are automatic to respond to fluctuating water levels. Lastly, the specification for potable water is incorrect, as pump tanks are predominantly associated with wastewater rather than drinking water applications.
