Question 70

A well pump for the potable water supply in a basement must be mounted a minimum of 12 inches above the basement floor.

To ensure safety and prevent contamination, a well pump for potable water should be mounted at least 12 inches above the basement floor.

A) 6

Mounting a well pump only 6 inches above the basement floor does not meet the safety standards required to prevent potential contamination from flooding or other water sources. This height is insufficient to protect the potable water supply.

B) 12

Mounting the well pump 12 inches above the basement floor is the correct standard. This height is established to protect against contamination from water intrusion and ensures the pump remains safe and functional in various conditions.

C) 18

While 18 inches is a reasonable height, it exceeds the minimum requirement. Therefore, while this option is safe, it is not the required minimum height for mounting a well pump.

D) 24

Similar to option C, mounting the pump at 24 inches is more than what is necessary. Although this provides extra safety, it does not conform to the minimum standard which is set at 12 inches.

Conclusion

The requirement for mounting a well pump at least 12 inches above the basement floor is crucial for ensuring the safety and integrity of the potable water supply. Options A, C, and D either fail to meet the minimum standard or exceed it unnecessarily, confirming that option B is the definitive correct answer.
