I chose this AO Smith reverse osmosis system because I wanted to install it myself and avoid the expense of hiring a plumber. I was able to install it myself but it was a bit of a hassle as the sink was so low but I managed. There was a slight leak when I first turned on the water, but after some adjustments I was able to use it with no further problems. I'm 74 years old and if I can do it, I believe anyone can! The instructions are very easy to follow. Tap water greatly improves the taste.
