i set my timers to run 1 minute for every 100lbs with a xtra 30 seconds to make sure i get a little water venting and lets the pump run a little xtra when emptying. so far so good, no issues.

now the one time I forgot to hook the bag up is another story, was very hard to get it back to 0% when there was nothing to drain and the system said i was 60% full.
