man thats nice, wish i could do that but i got my own well at my house so i have to treat all the water before i put it in my tank, because the water has high chlorine.
Tunez, a Python could still help you. You would just have to hook it up to an elevated water holding tank, where you could treat it, and then use the Python to send it to the tank.
This would, of course, depend on a lot of layout factors, this might work for you, and it might not, but it's just a thought.
