What is the difference between a positive and universal (negative head) shower pump?

Is my system suitable for a positive head pump?

A gravity fed system is either positive head or negative head, depending on the natural flow rate of the water in the home.

Watch our video to learn how to measure the water flow rate and discover when a positive head will work for the system. If you are unable to achieve the minimum flow rate of 2 litres per minute from all hot or cold water outlets that are to be pumped, you will need to install a universal (negative head) pump.
