Clear Water Concepts (owner Matt Ulrich) has been an excellent company to deal with. I had the full house system filter/softener and R/O system installed over a year ago and the system has worked great. We can certainly tell the difference in the water quality. The price of the unit Matt installed was much less than other quotes I received. Great company, great service and very fair pricing. Customer server for many companies is nonexistent, but these folks have their act together. Highly recommend this company.
