Abstract
The discharge ends of hot and cold water pipes are provided with valved outlets discharging into a common single water outlet and a by-pass pipe communicates the hot and cold water pipes upstream from but reasonably closely adjacent the hot and cold water outlets. A water accumulator is communicated with a mid-length portion of the by-pass pipe, a remotely operable flow-control valve is serially connected in the by-pass pipe intermediate the accumulator and the hot water pipe and an adjustable pressure regulator is serially connected in the cold water pipe closely upstream from the by-pass pipe.
