Is your flow impeded when running off the pump? If not the problem is in your incoming water supply. Look at the screen on the city water hook-up. Insure the check valve at the same location has not improperly seated. You can generally manipulate that with your finger or a screw driver on the white button. If you are running a pressure regulator and the park has one on the spigot it will often retard water flow. Let us know what you find.
