We had Pacific Water Conditioning Service install a RO under out sink and also connect it to the refrigerator.\n\nThey guy that came out was named Jonny, he was polite and professional.  He basically got right to work and was done in about an hour.  He went through the setup with me and showed me were the different emergency shutoff valves were.  He was able to answer all my questions and told me I could unhook my refrigerator filter and that would bypass the filter so the water was straight from the RO.  (some refrigerators you can undo the filter and others you need a plug to bypass).\n\nBefore he left he ensured there were no leaks and said check it for the 1st couple days to make sure there are no leaks and if there was to give him a call.\n\nWe have had the unit for a few weeks with no issues and saving space in the fridge where the brita used to be.  You can definitely taste the difference between RO and brita.  \n\nGreat service, would recommend.
