My kitchen sink has a GE Profile RO system, which is fed by softened San Diego water.
When the system was about 3 years old, we started having frequent leaks under the sink that we traced to the RO faucet. Checked the drain line - it was clear and working fine. The base of the RO faucet looked bad, with some evidence of corrosion to the metal and to the gasket.
Plumber replaced the base (which contains the air gap and the electronics), and we saw on disassembly that the air gap itself had badly corroded. He said that was the cause, and the new faucet with a fresh gasket has worked fine for a year - but the leaks have returned. When the problem is happening, it's slow drips along the outside of the drain hose from the air gap to the drainpipe - and, no, the drain hose is not clogged.
So, of course, I again suspect corrosion. It's impossible to get a look at the air gap without a lot of disassembly, but at this point I'm losing confidence in the GE faucet's ability to handle the waste from the filter. I'm wondering whether to try some other brand of faucet, or whether it makes sense to replace my dishwasher air gap with a dishwasher/RO combination air gap. A lot of those products have plastic parts, which may better withstand the (apparently) corrosive wastewater.
In all my searching, I have found NOTHING about corroding air gaps, but it does happen and I'm trying to figure my best path forward.
