Automatically turn your home RO system on and off according to the tank level. These diaphragm valves work in conjunction with a pre-pressurized tanks (sold separately) to automatically turn the RO system off when the tank is full, then back on when the tank level drops below a certain pre-set point.

Operating on pressure from the bladder style tanks, the diaphragm is engaged when the pressure from the tank exceeds approximately 65% of the incoming line pressure. This stops the flow of water to the RO system until the tank level is lowered enough for the pressure to fall below this level and allow the feed water supply to resume.
