I had an excellent experience with Advanced Water Resources. They are knowledgeable, quick, and efficient. I had a water softening system as well as a reverse osmosis filtering system installed in my home. I was really pleased with how well the system was installed and it works really well. There have not been any problems and I only have good things to say about the quality of the work. Their customer service is also great. The sales representative was smart and lovely to talk to. The technician who installed the systems was fast and knowledgeable. The pricing is not cheap, but the quality of the products and the great installation process trumped any concern about prices. I would definitely use them again if I had to and would recommend them to others.
