Trouble Shooting Reverse Osmosis

With customers Australia wide, the ability to analyise problems with a view to ensuring all Purestream products operate effectively. Even with the very best premium systems, water quality etc can affect performance.

To ensure you are not on your own, we have technical staff who can walk you through any areas of concern to ensure a continued water quality.

Noisy or excessive vibration

  1. Close tank ball valve – turning 90 degrees.
  2. Tilt the RO system the right, ensuring the end that has the pressure guage is now higher than the other end. Place somehting under the carbon filter housing.
  3. Turn on the pure water faucet at the sink.
  4. Let pure water run through the system for 2-3 minutes. This will help dislodge any air bubbles form the check valve.
  5. Turn off the faucet. Wait for about 10 seconds.
  6. Repeat the previous steps 3-4 times. If you see air sputtering out of the spigot, repeat until pure water can flow smoothly from the faucet, or until the noise goes away.
  7. When the noise is gone, open the tank valve and let RO run as usual.

Low Water Pressure

Firstly - turn off stop valve on top of tank and open faucet.This allows the unit to bypass the tank and make water directly to the faucet. It also allows assessment of water pressure through the membrane indicated on the membrane pressure gauge. This should read 40psi+

We would suggest you measure the amount of water produced at the faucet - working on 10-12 litres an hour, the system should produce approx. 200 mls. This allows you to confirm correct performance.
