Hi there, I have a 1999 Lund Pro-v. It has two livewells, each with a bait well on a second level. When I use my fill switch, manual or timed switch, one pump runs the livewells. On the other side of the livewell is another pump. I thought this was for recirculation, an option that I have, but when I switch it, I see the same pump working. Is something weird here...why does the other pump not do anything?<br />Any help or ideas would be appreciated!
