I plan on removing the old water softener; and once that is done I have room to install 2 50 gal tanks and a utility sink. Space is not a big issue there.
Total cost over 1k is not an problem; I am just trying to do the impossible; get value for the money spent. My bonus would be to remove the water softener; better located on/off valves to isolate on both sides the water heater. It would be perfect if I could get 2 additional hose attachments to support a mini-washer/dryer in the utility room.
I might try to stack up a few other smaller projects to keep a plumber busy for at least 4 hrs.
