Hi John,
I live in OKC. I was looking at my tank thread.....this time last year I was taking tile up to get the stand in.....
Here is where I am at today....
and since you kindly showed your plumbing........
I also drilled the tank myself.....a scary proposition but really allowed me to work the designs in my head a great deal before I ended up with the final system.
---didnt want to steal your thread.........
Paul.
