the return pump is an external pump. As far as I have noticed it really doesn't need anything to keep it primed so I don't use it anymore. I will take off the check valve, but then what is causing the bubbles?

the fittings going into the pump are 1".

there is plenty of room in the sump for the water that will come from the tank.
