Advanced Water Resources took care of me when I called and they answered my questions. They were very polite and nice, and they did what they had to do. First of all, they installed a water softener system in my home, and I haven't had any problems with it. I didn't know how to change the salt bags in the water softener, and they showed me how to. Now all I have to do is press a button to use the water softener system. They made it easy for me to use. They put me back on track. They now come once a year to service it and change the fillers. I have no complaints.
