I paid too much
Don't bother with the squeeze ball. I paid $90 for this thinking I would save water by manually drainning.  You need to run the faucet to drain water out of the tank. There is nowhere to attach the squeeze ball because the ends of the hose won't let it attach.  Made me Super mad.. The product itself is worth it (though not $90).  Once you get used to it and experiment, it does certainly save your back.  Instructions were not as clear as YouTube videos.  I would watch one or two before your first time using it.
