I hope this is the right place to post this, and help would be appreciated.
I've have been working on a multi tower hydroponics system for the past couple of weeks. I'm currently trying to figure out how to get the pumped water, back into the water tank. However I'm having issues with the water overflowing in the return pipe, and not flowing into the tank(5 gallons).
The return pipe has holes drilled into it, which the towers water return sit in. This is where the water overflows, because it is not going into the tank. I was hoping that the suction from the pump would be enough to force the water back into the tank, but I was wrong there.
Any suggestions, how can I have the water flow back into the original water tank?
I'm no expert so sorry for the amateur diagram.
