The Python is based on a venturi type pump originally made as a waterbed 
drain device. It uses the force of the hose-water tap at full flow to 
suck aquarium (or waterbed) water into the body of the bump and then 
force it out with the tap water. Inside the pump is a venturi that 
creates the pressure differential to suck in the water. So the whole 
time you are draining water from the aquarium, you have the tap running 
full blast -- as much as 6-12 gallons per minute of fresh tapwater going 
down the drain.

Or just do what I do, use the fuacet pump/venturi to start the syphon, 
then pinch off the hose, disconnect and run the hose to the toilet, 
lower drain, window, etc.  In my case, I live in an apartment and the 
bathroom is off the kitchen.  I Use the fuacet pump in th ekitchen sink, 
disconnect once the syphon is started then move the hose to the toilet. 
  Closing both lids holds the hose in place.

once the tank is drained (I do my glass cleaning and some maintainence 
during this time) I start the sink with the pump open and wait till the 
water temp stabalizes where I want it, add some Prime to the tank and 
close the pump so it fills the tank.  Works for me:)
