Return Pump Size?

Yes, my return goes through the wall of the overflow. I thought back flow would stop once it dropped below the teeth, but I wasn't sure. I planned on putting ball valves on both the drain and return line. Does it matter where they are placed, i.e., should they be closer to the bulkheads of the tank, closer to the sump, or doesn't it matter? Also, I just want to make sure there's nothing wrong with using flexible hose below the tank and just clamping it, or is it better to go with PVC?
The bulkheads are obviously threaded to tighten them down, but the 3/4" bulkhead is a slip on both ends (above and below tank), and the 1" bulkhead is a slip below and it has almost a cup on the top side that the standpipe fits into. Do they make bushings that are a slip on both sides?
My only other dilemma is that the bushing that goes through the overflow wall for the return is more or less just a smooth bushing. There is a bit of PVC for the return to slip onto, but on the tank side, there isn't anything. I was hoping to use a Loc Line so I could position the return flow, but the Loc Line connectors are all threaded. Any suggestions there?
Thank you for being so patient and helpful. I think I'm almost all set on this!

they do make a slip on fitting, it sounds like one side of the bulkhead is a male slip on and the other side is female. You could take one of the bulkheads to the hardware store with you and make sure you get the right size to fit the bulkhead, and from there you can go up in size, so the slip on fitting will be called a reducing bushing and the other side that the pipe goes on can be either slip on or threaded. Hope that all makes sense, once you get to the hardware store and look at all the fitting it should give a better idea of what I'm talking about. and if posible I would go with the pvc, I think it makes a better piping arrangement and easer to install your valves and fitting, I have used some flexable pvc in some cases that work well also. The valve placement you would want the one on the discharge close to the pump and. I put mine on the supply down by the sump for easy access.

Alrighty, I think you have armed me with just enough information to make me dangerous!
Actually, it's all making sense, and I actually feel like I can get this set up without much trouble. Thank again. I really appreciate the help!
