Mine has never leaked, it's great that it has a computerised back flush in it. Good design all around. The problem is the built in TDS meter. As soon as it is done making water or flushing the system the TDS meter goes up to 50ppm right away. So either the meter is plumbed in to the wrong spot on the unit or the meter is screwed. I've replaced the membrane but it has not changed. With a hand held TDS meter the water is 0ppm. I figure I should not have to own a hand held if the unit comes with one built in. I don't like buying things that do not work properly or half assed. My only compaint is that i'm not getting any help from the manufacturer. And when the rep tells me that it was a store demo and so no warranty, well thats not good support. I will send pics of the labeling. Very cheesy as they were put on with scotch tape. To me it looks like some kind of welfare peice of crap that I wasted $500 on
