Pythons are great!! I have used them for years. Make things so easy.

Here is an easy DIY tip..... especially if you dont have a gravty fed system.
The pythons end is usually connected to the sink and the suction is created by the water flow of your faucet. Lucky for us....the EXACT same unit is used in a $5.00 waterbed fill kit sold at walmart. All you have to do then is get yourself a hose from the garden department. And there you have it. A Python for usually 1/2 the cost. I also have a medium gravel vaccum style syphon that presses right into the hose end.
I can post pics if anyone is confused.
Have a Great Day
