I have replaced my Ecowater ER-375 system with an APEC RO-90 and have been using it primarily to fork off extra parts on the ice machine line , which I have I already have. Ecowater uses 3/8 inch fittings so I had to go to the hardware store for a step down fitting. However, when I got this, I was still using latch and T-connectors. and some PEX included. All in all, the price was about what I would pay for a lock and T-connector at a hardware store, so I got the PEX I needed for free by buying this kit. If I did a clean install (and that's why I dropped a star), I don't think they give you enough PEX. That is, unless your fridge is very close to the reverse osmosis unit. 20' seems like a lot, but in my case the refrigerator can be 12 feet from the reverse osmosis unit. under the floor and back up, it wouldn't be enough to allow me to move my fridge around if necessary (including checking for leaks). Think about it, since APEC uses color coded PEX extensively when installing their system, I also think it would be nice to design this kit in a different color to make it easier for you to see which line goes to your ice maker and which goes to your faucet. Complaints are pretty minor. Overall, it's a decent price, and with all the parts included, installation is super easy.
