I got an RO filter recently. Problem is, we have to fill it from a
1 or 5 gal jug manually. I would sure like to have some info on building a DIY water storage tank that would turn the RO unit on when low, and back off when full. I think it could be done with a 5 or 6 gal plastic water bottle, with a spigot installed in the bottom. I hear the best type of float switch is actually an air column pressure switch. That would have to be rigged to turn a solenoid water valve on/off. So if I could find a source for a suitable air column pressure switch, and an electric solenoid valve to control the inlet water line, then I would be all set to build it. Or maybe there is a tank kit I can buy? Ideas?
