I'm planning to supply air to a few tanks in the basement using a linear piston pump. The pump will power mattenfilters and air stones. I want the same pump, which I plan to put on top of a shelf in the basement, to provide air for filtration and air stones for a tank on the main floor (one floor above the pump). Apart from check valves is there anything else I can do to prevent a siphon forming and the main floor tank being drained in the event of a power failure? I don't want the pump on the main floor.
