Water-Saving Pipe / conserve resources

Water-Saving Pipe
Water-Saving Pipe

When people need to use hot water on cold winter days, they often purposefully let large amount of water flow to waste first to avoid touching the icy water. This results in a significant waste of water resources. The “Water-Saving Pipe” is designed to conserve resources. Installed on the back of a faucet, the Water Saving Pipe can automatically detect water temperature and redirect cold water back into the pipe while permitted hot water to flow out of the faucet. The device is small, cheap, and easy to install. Moreover, since it is designed based on the principles of thermal expansion , the device requires no additional energy to operate.
