Japanese Patent JP2013528767
Kind Code:
A
Abstract:
The present invention relates to a method for circulating water through the inside of a pipeline, and to a method for saving water and preventing a water pipe and a meter from being frozen or bursting during the wintertime using the method for circulating water through the inside of a pipeline. The method of the present invention involves enabling a pipe arranged inside a hot water pipe to reach the front of a faucet or a shower valve to form a double passage, and connecting the pipe to a pump such that water circulates through the inside of the hot water pipe of a boiler to keep the temperature of the inside of the hot water pipe at a predetermined temperature level. Thus, cold water is prevented from being supplied during an initial use of hot water or a shower, thereby preventing a waste of tap water.
