Piggyback ballast not draining all the way

[Agowen]

I have piggybacked 750s in my 06 sante 220 and I notice that when i drain the tanks I have a gallon or two left in the 750s but the gauges for the stock ballast read empty. Is this normal or should it be completely dry?

Sounds pretty normal. A few gallons won't effect anything. Just make sure when you winterize they are emptied out completely.

Agreed. Pretty normal. Unless you hold the bag so the last bit of remaining water can drain down into the hard tanks while emptying, some water will remain.
