Air gap reverse osmosis faucets do tend to run a little noisy.
If the sound is driving you crazy, good news, there is a way you can silence it!
All it will take on your behalf is a pair of scissors, a few materials, and a little patience—no need to buy an entirely new non-air gap RO faucet just for a quieter option.
So, here is our handy ‘how to’ guide for bypassing your reverse osmosis air gap and possibly saving your sanity.
Here is how to bypass a reverse osmosis air gap:
A check valve is a device that will prevent dirty water from getting into the reverse osmosis system if there is a clog in your drain pipe. It is a standard component of any RO system that doesn’t use an air gap faucet. It is also known as an air gap adapter.
The great thing about bypassing a reverse osmosis faucet air gap is that it eliminates most of the disadvantages that come with an air gap faucet:
Air gap faucets can be super noisy. By bypassing the RO faucet air gap, you will have a quieter system overall.
The water lines in an air gap RO faucet are pretty narrow, and sediment and debris can build up and block the drain line. If this happens, water will flow from the air gap and onto your sink/countertop.
An air gap RO faucet is a specialized faucet that is designed specifically for use with an under sink reverse osmosis system. It may even be a requirement to have one if you have an RO system, depending on the plumbing codes in your area.
An air gap faucet contains three tubes that run up the faucet stem; one carrying the filtered water for use, one carrying the wastewater up the stem and past the air gap, and a third line where the wastewater uses gravity to drop down for disposal via your sink drain pipe.
The purpose of the air gap faucet is to make sure that if your drain pipe clogs, your RO system will pull air back into the unit and not contaminated water, which could jeopardize your RO membrane and health.
Check to see if your local plumbing codes require you to have an air gap faucet with your RO machine. If not, then yes, you can replace your air gap reverse osmosis faucet with a non-air gap faucet.
To do this, you may need to get an adapter as air gap faucets use a different size tubing to connect to the drain saddle than non-air gap faucets. The adapter is required in order to fit the 3/8” drain saddle connection to the ¼” drain line.
