EASY TO CLEAN PIPE WATER SUPPLY SYSTEM

摘要

PURPOSE: A water supply system for facilitating a drainpipe cleaning work is provided to easily remove and drain deposits from a high-temperature sterilization tank by opening a drain valve and an air inlet valve. CONSTITUTION: A water supply system for facilitating a drainpipe cleaning work comprises a high-temperature sterilization tank(20), a drinking water tank(50), a water supply pipe(10), and a drinking water supply pipe. The high-temperature sterilization tank has a high-temperature heating device(21) and a drain valve(23). The heating device heats water stored in the high-temperature sterilization tank. The drain valve removes and drains deposits from the sterilization tank. The drinking water tank stores drinking water sterilized from the high-temperature sterilization tank. The water supply pipe supplies tap water to the high-temperature sterilization tank. The air inlet valve is opened to send air to the inside the water supply system. The drinking water supply pipe supplies the drinking water sterilized from the high-temperature sterilization tank to the drinking water tank.
