When installing a remote pump for a waterwell in a basement, what is the height requirement for the pump above the basement surface?

1. 12 inches

2. 16 inches

3. 18 inches

4. 24 inches

The correct answer is: 18 inches

When installing a remote pump for a waterwell in a basement, having it placed at a height of 18 inches above the basement surface is crucial for several reasons. This height requirement helps to prevent contamination of the water supply. By elevating the pump, it ensures that any potential floodwaters or spills in the basement do not reach the pump, thereby maintaining the integrity of the drinking water. Moreover, positioning the pump at this specific height facilitates easier maintenance and servicing. It allows for sufficient clearance for both the installation of the pump and for any required inspections or repairs without the risk of undue exposure to moisture or flooding conditions. This requirement is also in line with best practices that ensure the pump operates effectively while minimizing the risks associated with the environment where the pump is installed. Overall, these factors contribute to the necessity of having the remote pump elevated to at least 18 inches above the basement surface.
