Does it drop off and
stay low? If my pump is running and there is air in the supply line (garden hose) it will shoot out a hard stream until it hits an air bubble, then the pressure drops until the bubble is pumped out, then the pressure comes back until another air bubble hits. It takes forever to pump out an air bubble.
