Recommended Customer Reviews

Chris was able to come out same day and fix my RO system under my sink and replace the filters as well. Very fair price and very responsive. Maybe most importantly, he didn't try to sell me on something that didn't need fixed or to replaced my entire RO system like a couple other services on here suggested without even seeing my system. It's nice to find a service that's honest.

Chris from 02h came out on a Friday and installed some new components to our RO system which had stopped working a couple weeks ago. He gave us a good deal, offered helpful suggestions about how to approach the problems we were having, installed everything quickly, and even came back later with a new faucet after noticing the one we had (not installed by him) needed replacing. A follow-up call the next day finished the experience and we would recommend him highly to anyone looking for good service and a fair price for reverse osmosis systems.
