What to consider when buying RO faucet

1. Types of faucet

They are different types of the faucet but reverse osmosis faucet is available in two designs

• Non-air gap faucet
• Air gap faucet

Difference between the non-air gap and air gap faucet

Air gap faucet has an air hole, threaded stem, and additional connection.

Non air gap faucet has a threaded stem and no additional connection

Threaded stem is where purified water goes and the additional connection is where drain water goes in and out

Air gap hole is used to suck air if there is reverse suction. Reverse suction is when dirt water clog the drain connection from the faucet to the house drain, water starts coming out the air gap hole

Non-Air-Gap Faucets do not require a drain connection like an Air-Gap would.

Air gap faucet make gurgling sound when the storage tank is filling up

2. Color

Reverse osmosis faucet is available in different colors. You can opt to choose the color that matches with your house decoration
