A high pressure switch will mount on the pressurized storage tank tubing. Air pressure above 10 psi can rupture it internally. Reverse osmosis tanks come in various capacities, depending on the maximum volume of water they can hold. Making sure that the pressure in the storage tank is correct when it is empty will allow the bladder to fill to its ideal capacity while still having enough air pressure to let it empty completely. Most standard reverse osmosis tanks are three to four-gallon tanks that work best when the pressure in them is between six and ten pounds per square inch (PSI), so the magic number that we are shooting for is eight pounds of pressure.

Since RO filtration is a slow process, it takes more time to push water molecules across the semipermeable membrane. 3. 3. Use an air pressure gauge to check the air pressure inside the RO storage tank. Check to see if there is still water in the storage tank by lifting the tank.

Continue The number one reason for low water flow from a reverse osmosis system is due to the holding tank losing its air pressure. Step 2. The standard air charge for undersink RO tanks is about seven psi when there is no water in the tank. You have to empty the tank of water in order to check the air pressure. To check the pressure accurately, you need a low pressure air gauge. You can find these at auto parts stores or hardware stores. High water pressure is one of the main reasons water heaters leak prematurely. Most experts recommend 50-60 psi.
