Excellent customer service. For those that order those large, heavy, 5-gallon water bottles for your office (or home)...call Water Group 7 right away. It's 100% easier and a peace to your mind having your drinking water directly connected to your water line. I love that you have instantly cold or hot water at your convenience...and many people say that they can tell the positive difference drinking from our water. It's what I serve to my family and all the children at our preschool. Mahalo!
