Thinking of trying this project for a hydroponic setup. If my pump is pumping water straight up from a reservoir; then will turning off the pump cause water to flow back to the reservoir through the pump?

I’m not too sure but my guess is that it will stay stuck in the tube until you turn it back on again—assuming the diameter of the tubes is the same as the ones I listed in the article. This is what happened when I actually tested the system.
