Hmmm I am going to have to think some more on this....
I don't think that I will have a problem as there will be baffles in the prop tank to keep it from draining completely, there will be durso/stockman overflows in the tank so only a couple of inches from the overflow should flow out....
On the plus side there is a drain coming through the floor on the far right hand side. I was planing on making the botom of the stand waterproof and allowing it to drain if I have a flood... If I wrecked the carpet my wife would kill me.
Well It looks like I will have to think a little more

Oh yeah.....Not sure if you are pulling my chain or not
But the closed loop flow will not affect the flow through the sump as the pump is just sitting in the sump in case of leaks.....the suction comes right from the tank to the suction of the pump and the discharge right back to the tank
