Reverse Osmosis Filter Reservoir Pressure

Introduction

Repressurize your reverse osmosis (RO) filter reservoir (water pressure bladder)

What you need

  1. Reverse Osmosis Filter Reservoir Pressure, Disconnect the water supply: step 1, image 1 of 1

    • Disconnect the filter from the main water supply

    • Typically this is a needle valve

    Edit

  2. Reverse Osmosis Filter Reservoir Pressure, Open the main water valve: step 2, image 1 of 1

    • Open the main valve to release the pressure from the reservoir/bladder.

    • Leave this open until you are ready to repressurize the reservoir

    Edit

  3. Reverse Osmosis Filter Reservoir Pressure, Connect air pump to the reservoir: step 3, image 1 of 1

    • Remove the cap from the Schrader valve (or other) and connect an air pump

    • Most reservoirs have a standard Schrader valve

    • For a standard Schrader valve, connect a bicycle air pump to the valve stem

    Edit

    • Use the air pump to (Gently!) force all of the water from the reservoir

    • Be careful to not over pressurize the reservoir/bladder! This may damage the filter!

    • (Gently!) pump your air pump as the water is drained from the reservoir

    • Continue (Gently!) pumping, to ensure all of the water is emptied from the reservoir.

    • Easy rule of thumb: if your pump has a built-in pressure gauge, generally avoid more than 10 to 20 PSI

    Edit

  6. Reverse Osmosis Filter Reservoir Pressure, Close the output valve of the reservoir: step 5, image 1 of 1

    • Close off the output valve for the reservoir

    • For most RO unit reservoirs, this is a ball valve on the top of the reservoir

    Edit

    • Release any over-pressure of the reservoir

    • The reverse end of most tire pressure gauges, a flathead screwdriver, or your car keys, are good tools to easily release pressure from a standard Schrader valve

    Edit

  8. Reverse Osmosis Filter Reservoir Pressure, Repressurize the reservoir: step 7, image 1 of 1

    • Use your air pump to repressure the, now empty, reservoir

    • Most reservoirs operate between 5 and 8 PSI

    • Consult the owners manual for your specific filter to find the optimum operating pressure for the reservoir

    Edit

  9. Reverse Osmosis Filter Reservoir Pressure, Repopen the reservoir: step 8, image 1 of 1

    • With the reservoir repressurized to the specified pressure, reopen the ball valve

    • Fin.

    Edit
Conclusion

Your reverse osmosis (RO) water pressure reservoir/bladder should now be repressurized!
