Professional people working for this company Wichita is a rare thing these days. Took off their shoes entering home! Everything explained. They have come back twice to test water to make sure system is running properly. Received cleaning products and love them! Water taste great! Noticed in a short time that my dishwasher is cleaner. Cookware and dishes are easier to clean, kinda like they have a Teflon coating on them. Nothing sticks! Coffee taste much better in morning! Would recommend this system to everyone.
