At the risk of shouting out my complete ignorance, and in the spirit of
trying to offer up an idea...

...maybe there is a blockage or restriction in your system, something that
keeps getting better every time you go into the system, even though the
work may have nothing to do with the blockage or restriction?  The noise
may have been cavitation in the pump if the blockage was on the suction
side, or just the noise of the pressure breaking down across the
restriction if it was on the discharge side of the pump - ?
