It wouldn't make a difference, the pressure on the float would be the same with or without a pressurized storage tank once the tank is full. The tank is simply an accumulator which stores volume, nothing more. The float will be able to hold the pressure from the RO but in my mind you'd be pretty foolish to hook a mechanical float directly to an RO unit without some kind of safety. This is a big no-no in the hobby and I'm surprised people actually do it. Tony has the right idea if you want to use a mechanical float for an ATO.
