I personally wouldn't trust a check valve that much. I do have one on my main return just in front of the pump, but it really isn't necessary. The sump will hold the drain down. The kind I have seems to work pretty well and it comes apart easily for cleaning - but it cost $40.
I wouldn't put returns on the bottom of the tank if they are not part of a closed loop. JMO. You could do a closed loop like that, even if you have to go over the side or through the side of the overflow box to tap into the tank water for the intake side.

I have the 3 1200 maxi jets with the mods on them ( they work like a charm) with a wave timer for the rest of the flow. I plan on getting the Wave Master Pro in the near future so the wave timer will have to do for now.
