Customer Questions & Answers

  • Question : What is a reverse osmosis system?
    Answer : A reverse osmosis system is a unit that uses a membrane filter to remove contaminants from the water supply.
  • Question : What is a permeate pump?
    Answer : A permeate pump is a device that increases the pressure of the filtered water, allowing for more efficient water flow and better water quality.
  • Question : Is this valve compatible with other RO systems?
    Answer : This valve is designed specifically for use with the ASO and ASOV RO systems and may not be compatible with other systems.
  • Question : Can I use RO with 82psi pressure without a pump?
    Answer : You can, but it is not a big advantage. Using a permeate pump cuts waste water down significantly.
  • Question : My booster pump comes on once the tank pressure drops below 40 psi but the ASO won't open until 35 psi. Will this work?
    Answer : Using the 90% valve will not correct this. Normally, a booster pump will have an electronic pressure switch that will start and stop the pump.
  • Question : Is a permeate pump required?
    Answer : Yes, it is required and eliminates the pressure fighting against it and cuts waste water.
  • Question : How high does the water pressure have to be in order for the ASO to function?
    Answer : The ASO does not work right below 30 psi.
  • Question : At what pressure ratio does this valve reopen to allow water flow through the RO membrane?
    Answer : This valve opens just 2 psi less than the 30 psi on input. However, sometimes this pressure changes.
  • Question : Will this keep my permeate pump from cycling on and off every 3 seconds as the tank gets near full?
    Answer : No, the permeate pump cycles on and off every 3 seconds when the tank is almost full because that's when the pressure is the highest in the tank. The pump has to work faster to fill it.
  • Question : Will this valve work with a booster pump?
    Answer : This valve is designed for use with a permeate pump, but it could be used with a booster pump depending on the system.
  • Question : Where can you find a detailed connection diagram for the 1000 permeate pump with a 90% ASO valve?
    Answer : You do not need both. As both are valved off when pressure is high enough.
  • Question : Is the 90% ASO valve needed if a tank pressure switch and an ESO are used?
    Answer : No, the 90% ASO valve is not needed. However, the ESO is recommended to avoid incidents of the pump running against a closed shut-off valve.

AFW Pump Accessories Editorial Review

The AFW ASV90 ASV90-14Q 90% Auto Shut Off Valve for Reverse Osmosis is designed to work with a permeate pump. It is not a significant advantage to use without a pump, as it will still result in a higher waste water ratio. The valve may not solve issues with booster pump pressure switches. It is recommended to contact the seller for detailed setup instructions with a permeate pump. The valve cannot function below 30 psi and reopens just 2 PSI less than the input pressure. It does not prevent the permeate pump from cycling on and off. It can be used with a booster pump depending on the system. Some users found the instructions and diagram unclear, but installation was still manageable. Overall, customer reviews were mixed, with some experiencing issues with the valve not working properly or not meeting expectations.

Pros

  • Significantly reduces waste water with a permeate pump
  • Helps maintain respectable flow with a hot water tank
  • Keeps TDS low with a permeate pump

Cons

  • May not solve pressure issues with booster pumps
  • Unclear instructions and diagram
  • Valve may not shut off at the advertised 90% pressure
