Troubleshooting/Maintenance
Air gap is typically required by code
• Creates separation between RO unit (backflow prevention)
Water that backs up in the drain line goes out of air gap rather than back to RO
unit.
Installation errors
• Is the drain saddle installed nice and straight?
• Does the drain tubing that connects from the air gap on the faucet to
the drain saddle have any loops or dips in the line?
o Should be installed as short and straight as possible in a
downward path.
Obstruction in the drain tubing between air gap faucet and drain saddle
• Disconnect the tubing and blow through it in either direction to make
sure it is clear.
