This video is intended to illustrate some disadvantages and issues associated with using LDH or Large Diameter supply hose unsupported connected to a hydrant. I go over the basic friction loss formula to work backwards to determine the approximate available GPM based on the pressure in the water main and the friction loss in the 5-inch supply hose.
