What is a potential effect of a clogged intake screen on pump performance?

Explanation:
A clogged intake screen restricts water entering the pump on the suction side. With less water being drawn in, the pump can’t deliver its normal flow, so the overall performance drops. It won’t make priming faster (actually it can hinder priming), and it wouldn’t cause an increase in head. Friction losses are tied to flow, so they wouldn’t be the primary effect of the restriction. The clear, direct consequence is reduced water intake.
