My photo club has a functioning Jobo ATL 1000 without any procedure for recovering chemicals. The posted instructions says to let it pour everything into the drain after use.

If I understand the ATL 1000 manual correctly it's possible to recover chemicals using a "Chemical Separator #4220", but we don't seem to have one. Can I still recover chemicals somehow? There's a water supply hose and a water drain hose, but no hose on the chemical drain outlet. The processor is set up to sit in the sink on an upside-down dishwasher plastic tray, so that spent chemicals can be dumped without soaking the machine.

I know there are people using it for one-shot BW, but I was hoping to use it for C-41 and that's kind of uneconomical to do one-shot. Do you learned gentlemen and ladies have any wisdom to share?
