The water in Ewa Gentry are area is so bad, I needed a water softener system. After contacting and getting quotes from a few companies, I chose Water Group 7. The water softener has been in my house about 4 years now and it works great; very low maintenance. I just had an annual maintenance visit to assure everything was in shape and it was. Things I like about this company: professional, courteous, accommodating to my schedule, reasonably priced and doesn't try to oversell me. If you have issues with the water in your home, definitely consider Water Group 7.
