Yeah,  the resevoir is unpressurized - but when the screen is plugged
you are blocking fluid flow to the suction side of the pump.  When it's
bad enough, the pump won't be able to supply enough fluid, and may even
suck air into the pump-inlet side, thus it will run air bubbles through
the hydraulic pieces.  That WILL cause noise in the system.
