I am planning on using a large pump (at least a dart) for my return and am concerned about siphoning the tank into the sump when the electricity fails. A couple of issues:
1. I intend to route the return flow to the bottom of the tank, so I guess I have to run the pipes above the water level first?
2. The pipes will be 1.5 inches diameter, so I am concerned a small air hole will not work well, and if I use a large air hole, too much water will be lost.
3. This will be a plywood tank, so drilling holes will not be an issue.
Thoughts?
