What is the equivalence of one foot of pressure head in PSI at the pump?

One foot of pressure head is equivalent to 0.433 PSI at the pump system. This conversion is based on the relationship between the height of a column of water and the pressure exerted by that column due to gravity. Specifically, for water, one foot of height generates a pressure of approximately 0.433 pounds per square inch.

This relationship is important in pool service and repair, as it helps contractors determine the necessary pump pressure needed to circulate water effectively through the system. Understanding this conversion allows professionals to assess pump performance and ensure efficient operation. This knowledge is also essential when calculating the total dynamic head in pool systems, which impacts pump sizing and energy efficiency.

Knowing the correct pressure head conversion can greatly assist pool contractors in troubleshooting issues related to water movement, filter performance, and overall system efficiency.
