Water Supply Pipe Capacities
Water supply pipe lines should be sized according to expected demand rather than total theoretical demand. Due to intermittent fixture usage, actual demand is significantly lower than the sum of all fixtures operating simultaneously. The following values apply to applications such as homes, offices, and nursing homes.
