Air Gap Faucet Bypass

Air Gap Faucet Bypass

Noisy air gap faucets may be silenced by bypassing them

You can use the same air gap faucet that you have as a non air gap faucet. No need to replace the faucet. Check local codes. See more on air gap faucets.

Remove and discard the 3/8" drain saddle and the short piece of 3/8" tube connecting it to the faucet base.

Install a new 1/4" drain saddle.

Disconnect the systems waste water (brine) line at the faucet.  Cut off the end and trim square the end of the tube that became malformed where it was connected to the faucet base.

Connect this line to the new 1/4" drain saddle.

Install the check valve shown below to prevent any possible back flow from the drain into the Reverse Osmosis system. Cut the brine line about 12" from the RO system and install the check valve. Do not install the check valve close to the drain saddle. The check valve comes with John Guest quick connectors. See How They Work.

Leave the line from the tank (permeate) connected to the center stem of the faucet. This is the only line that will remain connected to the faucet.  The 3/8" and 1/4" barbed fittings on the bottom of the faucet will no longer be used.  The faucet has now been silenced!
