Problems with air in my reverse osmosis
I hope someone can help me because I can't find an answer on google. I'm trying to figure out the issue with my reverse osmosis system. When I flip open the RO faucet to get water the pressure is good for a 1/2 minute or so and then I hear this air escaping sound and then I lose most of my water pressure. I'm not leaking any water. I have a three filter stage system with a large tank and the tube that runs into the stages shakes when I hear the air escaping sound. Can someone point me in the right direction?
