Does anyone have a good recommendation for a good in line auto pump out? I just purchased a Jaguar MX- Cub and plan to do mostly residentials on the side where I don't mind hauling a few buckets. But for big commercial jobs I plan to have a 30 gallon water tank on wheels to feed from, now I just need a way to pump all that water back out so I can focus more on a good cleaning instead of running to the sink every 10 minutes.
