If the high point is below the overflow height the system should flow without having to have a siphon. The pressure of the water moving down will push the water up. The more water pushing down vs pushing up the faster it will flow.

Here's a link to a picture of the Brooks Aquaduct where the water goes under a rail line. This shows how water can drop and rise again using just gravity. Basically if there is more water pushing down than you are trying to push up the system will flow

If the point you have to go over is higher than the overflow you would need a siphon making this layout risky - siphon break could cause a flood.

One thing you can do to test this would be to setup a couple buckets and a hose running the route. See it the hose will flow or not.

are the tanks on the same floor, or different floors???Also when you say it has to go 16' is that 16' vertically or horizontally???

if its verticall you can just use a pressure rated pump....the reeflow snapper pumps are good for 26' i believe

yes I need to run it verically.....(up into the ceiling and back down)
Sounds like a pump like that could work...as long as it doesn't increase the flow unpredictably.
any idea where i can get a pump like that???

There's no problem of getting pumps with high head, I'm using a Iwaki with a basement sump and something like equivilant of 16' of head, the issue is going to be your drain. I would stay away of anything that basically is going to need to work as a siphon.

Most stores should be able to bring in pumps for you. If you want details on Reeflo pumps the website is reeflopumps.com
