Ok, I reduced the number of three way valves... then found a supplier that actually sells some reasonable ones. (i.e. not $383 each) I added the Propane lines and the whirlpool on the brew kettle. The Hot Liquor Tank we're getting doesn't have a fill inlet at the top. I might ask them just how much that would hurt to add. That would be the only place we need loose hose.
Not too sure what to do about the two flow control valves (propane and water). Most of the rest of the equipment is sourced. Perhaps I'll post the equipment list later.
