Watts Premier WP116094 Air-Gap, Top-mount, Monitored Faucet, Chrome

This is a top mount Chrome reverse osmosis and water filtration air-gap faucet with a bell shaped base. It's monitored and will alert you when it's time to change your filters. This monitor works on a timer system based upon the amount of time the faucet is in the on position and doesn't test the quality of the water from your filters. When it's time to change the filters, you will be alerted with a blinking red light when the faucet is dispensing water (a blue light will be blinking when good).
