The perfect project for the weekend DIYer, update your Delta Marca pull-down kitchen faucet to Touch2O Technology with only a few common tools in your toolbox and this conversion kit. Whether you have two full hands or 10 messy fingers, Delta Touch2O Technology helps keep your kitchen faucet clean, even when your hands arent. A simple touch anywhere on the spout or handle with your wrist or forearm activates the flow of water at the temperature where your handle is set. The Delta TempSense LED light changes color to alert you to the waters temperature and eliminates any possible surprises or discomfort.
