Try as I might I can't figure out where water is coming in. I have checked all the livewell plumbing fittings as well as the cartridges and tightened as best as I can. It's hard to get to them. After 1/2 day of fishing, I have well over a gallon in the bilge. Water from ice in cooler is not the issue, no ice used. I make a point not to backwash when I stop, so not much there. Am I missing something? What else can I do? It's enough that the auto bilge will come on.
