Cold water subrogates hot water supplied to a leaky hot water faucet. An individual kitchen or bathroom faucet set incorporates the anti-dribble control feature to substitute cold water trickle for wasteful hot water trickle through the leaky hot water faucet. When the leaky faucet is turned "off" the supply of hot water feeding the faucet is stopped and a limited flow of cold water replaces the hot water supply to an extent necessary to feed the leaking trickle of water. In effect, usual hot water dribble which may leak through a faulty faucet is eloquently displaced by a sacrifice of cold water.
