So I love my python but hate how much extra water it uses when I am dumping water. Do you guys think it would be possible to add a "T" or something to the line to add a external pump so that I won't have to use all that extra water? I figure I can add the "T" with a valve and open it so that I can pump water out and then turn it the other way to let water through the normal hose to refill the tank. Good idea? Has anyone done it?
