Well, final try before I tear out the whole mess and start from scratch yet AGAIN with everything new (including the RO system). I cut the line going up to the sink faucet. Logic is telling me something nasty may be growing in that faucet. So I cut the line, got a piece of sterile silicone tubing, slipped it over the remaining line going up to the faucet. Mixed up a very strong solution of bleach and water (about 3:1) 3 parts water. Put in a squeeze bottle and placed the end of the bottle into the silicone line and run the contents through the faucet then, closed it as it neared the end to keep solution in the faucet and remaining line. Going to leave this in there for about 15 min. Then flush it all out with fresh water, finally hooking back up to the RO line, flush again until no odor remains. Then we wait and see what happens. I have doubts the taste/odor is coming from the final pressure tank because if it was why is the fridge tap not seeing this. Both have carbon block filters as "finals", both are fed from the same pressure tank. So, from a logical POV it's pointing to some type of "nasties" in the faucet.
