I have a python but I don't use it to drain water. You have to turn on water at the python adapter connection to get a good siphon and if you dont like wasting water then that's a bad idea because you waste a lot of water draining with a python.
Instead I bought an extra large gravel vac and siphon the water into a big trash can I put nearby. Then I put a regular pump (I use a Rio 26 hf because they're cheap and powerful), connect it to a 50ft garden hose, and run the water in the trash can all the way to my trees and grass. You waste no water that way and the siphon is faster than with a python. I like this method because you can vacuum the sand to get all the dirt and it drains fast.
I use the python to refill my tanks. So I bought a faucet adapter and connected it to the female end of the python and my bathroom faucet. Then I turn on both hot and cold water to it to try to match the old water's temp. If you want to use the python to drain all the water to your garden, its either going to be really slow or you waste a lot of water.
