ok so after some more troubleshooting i found the issue. after unhooking everything, i took the unit somewhere more convenient to work and figure what the heck is going on. i apparently after i removed one of the canisters and then reattaching, i inadvertently squished one of the tubing. it is a pretty tight fit with that last canister and some of the tubing and is seated behind the canister. i did not realize that i was kinking the hose when i screwed the canister back.
and upon unhooking the tubing from the faucet, i also caused a pretty bad leak from the washing machine's faucet. luckily i was able to tighten it, so now there is no more leak.....thank god.....LOL
so i just took a cigar break and now i'm off to re-hook the unit back. this was a good lesson and a great way to learn how things work on my RODI unit.
