As far as the 2 litter bottles popping you really don't need to worry about It. Have you ever dropped a full bottle of soda? There's more pressure there than what you'll be producing with the diy setup as long as you don't stop the flow completly, and you won't be producing enough fast enough to worry about leaks. The only reason to worry with leaks is less co2 making it into your tank, a small leak with really lower the chance of the setup pushing all the way to the bottom of your tank and through a diffuser.
