Originally I had designed it to refill an RO
auto top off resevior that would have been on the shelf. However after, plumbing and electronics it limited my room for a decent sized resevior (4 Gallons was all I could get). I since have opted to run an RO
line through the floor from the basement. I am still undecided if I will include a small gravity fed fuge on the shelf, or leave it open and put and even larger sumpfuge in the basement. It still has a way to go, but getting closer and closer every day. Thanks for the kind comments. Constructive criticism is also welcome.
