I would guess there's an electric solenoid in the system between your freshwater tank and your toilet bowl. The solenoid is what opens when you press one of your control buttons to demand water.
Solenoids can go bad, stick open, or just get clogged with a bit of calcium (or whatever) grit. Find it, take it out and clean it, try it again, see if it leaks. If it does, just get a replacement from Raritan.
