You can install a small booster jet pump system, but your neighbors may not be happy if you start sucking all the water out of the main and they dont get any.: I just built a new house and found out from one of my : neighbors that our water pressure in the area is low : because the old water tower cant keep up with the : demand of the new construction in the area. Is there : anything I can attach to the main water line coming : into my house that will increase the water pressure : through the lines? The valve is open all the way now, : but the water pressure is still too low by my standards.
