by having the ball valve at the bottom of the tank it would only open when the level dropped enough to open it once they were near empty. It would stay closed the rest of the time. I'm thinking of a ball valve that you have in a toilet.
A mechanical float valve is what I should have said.
damoelld, I meant float valve connected to mains not ball valve, mounted low in the tank, to protect your pump from running dry.
My only advice would be to add a ball valve near the bottom of the tank connected to mains so your pump never runs dry.

Nice instructable!I want to setup a cloud on Linux Mint that is only accessible at home. I don't need it to be accessible over the net. We use iOSX, windows and Linux on the tv streaming computer. Is this an easy setup? How do I do this?
