Well I tore the top off of the ATL-3 today and figured out that the drain bits were broken and/or missing. Bummer. I disassembled the drain, went to the local fix-it store and bought a bunch of drain parts. I can plumb it to my standard downpipe from the sink fairly easily, and will do that tomorrow. I am thinking for now I will just put a drain plug in the tempering bath and have plans to put an in-line ball valve in the drain from the tempring bath. I'm actually relieved that I've found out that this was all bunged up, now I have a plan and the parts to execute. Stay tuned...(if you care).
