anybody else ever have problems using the python no spill? i tried using one for the first time and it hardly got any suction. i checked and made sure all the connections were air tight. could it be that the water pressure of my bathroom sink is way too low? it sucked some water through the tube but the water couldn't even make it uphill through the tube into the sink. am i doing something wrong or is my faucet just not good enough to use the python correctly. i thought about getting more hosing for it to connect to where the garden hose is but thats crazy far because my room with the tank is upstairs.
