The Automatic Shut-Off Valve for RO Permeate Pumps (ASV-ERP-JG) is a 'must-have' fitting for reverse osmosis systems used in settings with low water pressure levels. Installing a permeate pump will improve the water pressure and flow through your RO system, but you'll definitely want a new ASO valve as well. Adding a new, specialized shut-off valve will boost the shut-off capacity of your system from the standard 65% to as much as 84% 'feed water pressure' from the holding tank.

The TIER1-ASV-ERP-JG is comparable with the following part numbers



  1. The valve automatically shuts off production when the tank pressure reaches approximately 78% - 84% of the incoming line pressure to indicate the tank is full
  2. The ASO valve saves thousands of gallons of water. Reverse Osmosis Systems without an Automatic Shut-Off valve continually send rinse water to the drain even when the tank is full
  3. Note: In low water pressure areas the tank will not fill completely, but the tank will be more full with the the ASV-ERP-JG than without
