Hello: My issue is that the RO system I have will not discharge water at the faucet. Here is what I have done so far: All filters have been replaced and the Flow restrictor was replaced. The tank was removed and checked for pressure initially and it was fine. When I replaced the tank and installed the new filters the tank did fill with water but I have not been able to get any flow out of the faucet. I loosened the connection on top of the tank and water sprayed out so the tank is definitely pressurized. What am I missing?

Hi there, I have one of the Kinetico whole house softener and filter combinations, the one with 2 stacked tanks on each side. Its been installed and mostly perfect for about 15 years now. We once had the filter media changed about 7 years ago. Lately, I notice that when we fill the bath tub, the hot water side is a touch brownish/yellow in color. This is new behavior. We are on city water. I have read that in some cases where there's iron in the water, or other minerals, that the color can change, but I wouldn't expect our city water to change that much abruptly? Anyhow, I've called the Kinetico dealer, and of course their response is "we should take a look at it" to the tune of a $175 tune up - which I'd rather not pay if I don't have to - and they won't talk to me over the phone about it other than just to make an appointment to come look at it (learned a lesson about this company - oh well). Any suggestions? It's a ~2 year old hot water heater, so I'm thinking it should be relatively clean as well. Just looking for suggestions. The only thing I can think is that the resin probably is due for replacement - would that cause the water to change color? Near as I can tell, its only the hot water, which makes me think hot water heater, but I'm still a bit confused. Thanks for any pointers.:)
