This statement from Barry is confusing to me:
"Everything came back into a smaller tank that was inside the unit, and the larger tank, which originally was going to be condensate return tank, and then we were going to pump the water back into the units."
Looking at the photos re-posted by BL (thanks by the way), it looks to me like the external tank is situated higher than the internal tank, but the angle of the photographs makes it pretty hard to determine exactly how much higher. Barry suggested that the condensate water returns back into the smaller tank and the larger tank. But some here are guessing that the larger tank was only used to start the system up or to replace water that might have leaked. So which is it?
