One of the engineers on our dept. feels he needs to put the pumps into gear and run them for 30-45 minutes every morning that he is on shift. He runs the pressure up to about 50 psi so its not that much but does anyone know if this could potentially cause problems down the road. We've already had to replace several discharge valves on a couple of the engines, is this practice of 'deadheading' the pump causing the valves to wear out?
And yes the pump is circulating the water while running.
