had Kevin from Culligan out to talk about a Reverse osmosis water filter for the kitchen sink and ice maker in the fridge. There were two systems one with a tank and a bigger tankless unit that can make up to 600 gallons a day. We went with the tankless one. This was our Xmas present to us this year. Kevin came out a couple days later to do the install. He ran the water line through all the cabinets to the other side of the kitchen and hooked up to the existing line in the last cabinet next to the fridge for the ice cubes and cold water. . Then he went back to hooking up the lines under the sink, then installed the RO device also under the sink. About the size of a P.C. tower, fit nicely up against the wall inside the cabinet. He drilled the hole in the counter top for the faucet, for the dedicated drinking water and connected that. Then we were ready for some very clean tasting water. Some times our well water has a very slight musty smell , no more with the new filter. There is a little light array on the front of the faucet to monitor filter use so you don't have to crawl around under the sink. Kevin did a wonderful job,so if you are looking for a reliable source for clean water call Culligan.
