Got it...ok so I can have 2 return lines to the main tank and then one bleeder back into the sump. BUT I will have 2 T's in the equation, 1 ball valve, 1 bleeder back into the sump, and 2 return lines. So basically come out of the pump into a T, the straight part going up towards the tank and the bleeder heading back into the sump. The install a ball valve above the 1st T, the above the ball valve have another T, with one going to one side of the tank and another to the opposite side of the tank. I think this is it...Thanks for the help and let me know if Im still missing something..
