Were these disconnected from the switch/lever on the boat? I broke one switch this spring and having some difficulties trying to find one right now. But what I’ve done is unscrewed the plate that the switches attach to, and move the cable with my hand, verses using the dial on the front. Makes draining the well easier verses me sticking half my arm in the well to pull the plug.
The recirc option recirculates the water that is already in your livewell. Nice for keeping good water in the well if your waiting in a marina to weigh fish, or for keeping bait alive over night. Just switch the toggle over to recir and it will cycle every 3 or 5 minutes.
Now if you’re looking to add an oxygenator, you would want to get this fixed. I’m pretty sure with an oxygenator you fill the well up with good clean water, switch the well over to recir and the oxygenator will add to that water. It would defeat the purpose of the oxygenator if you kept filling the well from the lake, only to have it flow out the over flow back into the lake.
