Thanks Terry. I now see and understand the concept, but if it needs to be plumbed outside the tank in the back its not going to work with my space restraints unless I make the tank narrower. Like I said 30" ia my max and I'm only leaving 1" between the wall and the tank.... even at this its pushing it. Frankly, although a coast to coast would be real trick and clean, I don' think its going to work for me.... Unless you know something I don't!!!!!
