Abstract
A faucet spray head having a volume control mechanism allowing the user to adjust the flow of water through the spray head from a full-spray to full-stream and to a paused flow and flow levels therebetween. The volume control mechanism illustratively includes a spring-activated safety mechanism that prevents the user from inadvertently leaving the faucet head in an off position, thereby preventing the mixing or backing up of hot water into the cold water supply.
