I am installing a watts premier model WP-4V ro system. I can't find which hoses attach to where on the faucet. Does anyone have any idea? There is a red 3/8"hose and two 1/4"hoses. One is black and one is blue. Thank you for the help.

I had the same question and made a guess - black hose goes to the furthest connection end of faucet and the red/blue hoses go to the two connections inside the faucet itself. However, when I Google for the installation, I found the black and blue get switched. So plan to try that and see if it works. Not sure how to un-plug them at this point though.

I assume you are talking about Reverse Osmosis...

Blue is incoming water supply
Red goes to the dispenser
Black attaches to your drain

However, there should be instruction enclosed with the unit. See if you can locate them...
