What is the typical application of drinking water filter faucets?
Air Gap & Non-Air Gap drinking water filter faucets are utilized with RO, UF (ultra-filtration), single-stage (a sediment filter or a carbon filter), and dual-stage (sediment with a carbon filter) water filter systems. Air Gap faucets are typically used with RO systems only, as other filtration systems do not need the air gap. Drinking water filter faucets are separate from the main kitchen faucet and are attached to the cold water supply line. They can only be used with cold water.
Does the air gap have to be used?
No. Use of the air gap is optional. However, if you have an RO system, using the air gap is highly recommended as many local plumbing codes require it in the U.S.
What is the difference between air gap and non-air gap faucets?
Non-air gap faucets only have a filtered water line. Air gap faucets have three lines consisting of the filtered water line (permeate water) and the incoming and outgoing wastewater lines. An “air gap” is a siphon break to ensure wastewater cannot flow backward from the household drain system into the RO system. The incoming wastewater line sends wastewater to a non-pressurized trough at the bottom of the faucet before it goes to the drain. The drain hole in the back of the faucet is an escape hole so that wastewater can have a way out if the drain becomes clogged. This protects the RO system and the filtered water it produces from contamination.
What type of water filters require an air gap?
Only RO systems require an air gap because RO membranes produce wastewater, often referred to as “brine water.” Other under sink filters, such as carbon, sediment cartridges, and UF (ultra-filtration) do not produce wastewater.
What type of water filters can use non-air gap faucets?
Non-RO under-sink water filters.
What is the air gap? What does it do?
The air gap is a non-pressurized trough found at the bottom of the faucet. Wastewater from the RO system travels up to this gap and then down to the drain. The air gap trough acts as backflow prevention, so if the line became clogged for any reason, a small amount of air would flow back into the system instead of dirty wastewater, protecting the system and the filtered water it produces from contamination.
