How to Install a Sink Sprayer Diverter Connection

A sink sprayer is attached to the main water lines leading to the sink faucet. The faucet is installed with a diverter inside, which allows the sprayer, when connected properly, to stop the flow of water to the faucet and spray out the sprayer head instead. To hook up a diverter connection, you need a sink that has a hole to accommodate the sprayer head as well as a faucet that has a spray diverter already installed. The connection is easy to make from there.
