If the pump is working as it was designed to, the inspector will check the water flow to see how it moves through the system. They will test the rate of water flowing through pipes as well as points that should stimulate water movement at certain pressure ranges. The inspector will answer many water movement questions, such as the following: How long does it take water to get to major points in the system? Is the pressure tank signaling that more water needs to be delivered? Are pipes leading to areas of the house correctly filled with water?
