Auto Top Off System For Tank

[blugrassboy]

Hello all! As you guys know, the mundane task of toting buckets to your tank can get real OLD, real QUICK, as it has for me. I have a python, but I'd like to make some sort of auto top off valve. If I am thinking of this correct, I believe NO electricity should be needed. If any of you have ANY suggestions, or see a flaw in design, please speak up! I am going to attempt to make this contraption this weekend, should I get the answers I need here.

My 300 gallon is located in my living room. DIRECTLY below it, in the basement, is the main water supply to the house. Now, the way I see it, I should be able to run something like a tap (like what an icemaker uses) from the main, upstairs to the tank's sump. The only problem I am having is figuring out how to get the newly ran water line to SHUT OFF when desired water level is reached. The reason I say I do not believe electricity needs to be used, is because I plan to emulate a toilet in many ways. The automatic top off in a toilet needs no electricty.

Im hoping you guys can help me out. I'm going to buy a toilet repair kit this weekend at lowe's just to see the principal behind it. I will report back in. Thanks!!

you can use a float switch to turn it off (like the one in a toilet cistern). we have this type of thing on some of the systems in work. when the water volume drops, it gets filled with fresh from the mains, until it reaches a certain level and shuts off again
