My whole experience with Pure Water Works has been a NIGHTMARE! Customer service is totally non-existent. Don't expect anyone to call you back, even if they say they will. We worked very hard for two weeks to give Pure Water Works our business before finally cancelling and having Culligan take care of us. Contacted Culligan on Friday and by Tuesday the Health Dept. had their paperwork, the reverse osmosis system was installed, water was tested and we were able to move forward with our loan process. We wasted TWO weeks trying to work with Pure Water Works. No one would call back, they couldn't seem to get the required information to the County Health Dept. so we could even have the system installed. I was even told that the Project Manager would call me - that was a week ago now and haven't heard a thing. In looking at prior reviews (I wished I'd checked them first) it looks like poor customer service is a systemic problem within Pure Water Works and has not been addressed. My review: Pure Water Works = 0; Culligan = 10+.
