Very interesting. Do you happen to have a picture of the finished product? Thanks.The bad thing about the Python is that it relies on water pressure to suction out water. If you turn off the faucet during draining, it's very slow.
It's a lot more effectively to buy pool hosing from a pool store or sump hosing from HD and use that instead. That way you'll be draining water out of a 1 1/4" hose instead of the small hose that the Python uses. Plus you will be using gravity instead of using water pressure and wasting water with the Python.
I use this : http://m.homedepot.com/p/Flotec-Sump-Pump-Discharge-Hose-Kit-FP0012-6U-P2/100645330. You glue a 1 1/4" pvc pipe to one end and a shutoff valve to the other. Then you start the suction by sucking in air like a regular siphon. I can drain my 210 g tank in about 15 mins.
