Reverse osmosis gurgling after use
I've just replaced countertops and sinks in my kitchen, including replacing the RO faucet to fit in with my new decor. The under-sink tank and the cartridges were not changed. The original faucet was an air gap faucet, and the new one is not -- they said they could adapt a non-air gap faucet to work since the air gap faucet was not available in the color and size I needed. Now we hear gurgling after every use of the RO faucet. After running 16 ounces of water, the gurgling continues for 10 to 12 minutes, and it is audible throughout the kitchen unless we close the drain to muffle the sound. Running enough water to fill a coffee pot causes the gurgling sound to go on for a long time. Culligan never told me that I would have this gurgling problem. Is it likely that this is because of the non-air gap faucet? Any thoughts on whether this can be remediated? Or do we just retrain ourselves to close the drain after running the RO? :)
Thanks for any advice anyone may have for me.
