I have a fish tank with 3 sections. I am trying to create a single siphon pump that will drain all three sections at the same time.
On the lower pipe at the left before the hand pump I have used a valve.
In each elbow at the top, some airline pipe feeds in the top of the pipe and down the pipe on the outside of the tank a couple of inches. At the top of the air line pipe is a 1 way valve.
First I close the bottom valve, then suck the air out of each pipe to create a siphon.
Then I release the valve and some water will trickle out, i use the hand pump to pull the water out faster.
Now... all three of the tanks have drained, but not simultaneously, and it tends to be only 1 that will drain, usually the one on the far right, or far left.
Can anyone offer some insight here?
