do ya do that in the top of it im assuming...so once it hits air it'll stop? Thats one thing I never got good at was other than to plumb from here to there... (being that I plumb, lol) and knowing how to build (being that I can construct small things,lol) I dont get alot of the tricks and such ...
Most folks will drill a hole in their return pipe just at or right above the water line on the section of it that is inside of the tank. That way when power to the pump is cut, the hole allows air to enter into the return line and breaks the siphon the occures when the pump is shut off. But those have been known to fail as well. They can get blocked by algae build up, sludge or simply because a snail decided to park it's arse on top of the hole. So some folks will drill two holes for redundancy.
The three things I would consider are...
1. Placements of the output/ends of your returns.
2. If you simply have to have your returns more than a couple inches under water then drill siphon break holes in the return line at the water line..
3. And when ever possible, use a large enough sump to be able to handle all of the back flow that could happen in a worst case scenario.
Personally I've designed my system to account for all three of these things as well as water proofed the inside of my stand.
