Reverse osmosis faucet comparisons
What to consider when buying an RO faucet
- Types of faucet
They are different types of faucets, but the 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
The air gap faucet has an air hole, a threaded stem, and an additional connection.
A non-air-gap faucet has a threaded stem and no additional connection.
The threaded stem is where purified water goes, and the additional connection is where drain water goes in and out.
An air gap hole is used to suck air if there is reverse suction. Reverse suction occurs when dirt and water clog the drain connection from the faucet to the house drain. Water starts coming out of the air gap hole.
Non-Air-Gap faucets, unlike Air-Gap faucets, do not require a drain connection.
The air gap faucet makes a gurgling sound when the storage tank is filling up.
- Color
The reverse osmosis faucet is available in different colors. You can opt to choose a color that matches the decoration of your house.
