Dave, I ran a one step program and then manually set the volume at each of the preset amounts. So for example, I created a new program with one processing step, bottle 1, and with fill volume of 60ml. I then measured the reclaimed chemistry. In each case (i.e., at each of the preset volumes), the measured volume was significantly lower than the set volume. In some cases by more than 30%.

I only tried this with bottle 1. Mike, you may be correct regarding leaky seals or faulty pump. Logically I should try the same test with the other five chemical bottles. If it is a pressure leak, then the volume extracted from some of the other bottles should be fine. If it's a pump problem, I think I would expect the same problem regardless of the bottle. Does this sound loigical? I'll give it a shot this coming weekend and post my findigs.

Thanks,
Luigi
