Notice the concept of a natural water-vacuum (known as a siphon). For a siphon to work, a tube, or hose in our case, must have one end at a higher elevation than the other. If the higher end is submerged in water, it doesn't matter where or in what direction the rest of the hose travels, so long as the the other end is at a lower elevation. As you can see in the above illustration, the hose travels in every which-way before it reaches our reclining turtle in the low-elevation pond.
Now that the siphon is set up, it requires an artificial force, or for the turtledrain, a few foot pumps to get it started. This is a quick process, as we recommend 1 pump per every 3 feet of hose. So a 30 foot garden hose would need 10 good pumps.
Once there is water flow, you can sit back and relax and the siphon will handle the rest. The sucking end of the hose (the hose at the higher elevation) will completely drain all of the water from the pond you see in step 2.
Because the turtledrain is designed to be clog resistant, you can leave it alone and rest assured knowing the turtledrain will do the rest. After all, there are better ways to spend time.
