Review on Deionization Reverse Filtration System by Express Water by Roger Sanders

I've wanted RO/DI ststem for a long time. I maintain aquariums and plants that require very clean water. Tap water over 400 µS. This system reduced it to 5-7. If you have very hard water like me you can also get a whole house filter for pre-treatment (that will be my next project) but it does an excellent job of cleaning the water even without it. Installation on a stainless steel kitchen sink took about an hour. The hardest part was drilling a hole in the steel for the faucet, and it took about two minutes with a step drill or a hammer drill. The system comes pre-assembled, all you have to do besides installing a faucet is drill a hole in the sewer pipe and connect the pipes with the right color. If you wish, you can save the water for other uses and not install a waste water saddle. The taste of the water is great too. There are various upgrades that you can also purchase separately. I wish they had a 200lb/day reverse osmosis membrane and that's the only downside I've found so far. Installed about a month. The fact that it's reverse osmosis and deionized for the price can't be beat.
