Question: How do I check the pressure in my Storage Tank?

By

Procedure For Checking Your Storage Tank Pressure:

1. Turn the water off on the RO System’s incoming water line.

2. Open the faucet on your RO System and allow the water to run until the flow stops, then close the faucet.

3. Turn off the tank valve.

4. Is the tank heavy ‑ does it have water in it? Does it weight about 15 lbs? If the answer is yes, you will need to replace the tank as the bladder will no longer hold water. 5. The tank has an air stem just like those on a car tire. Just like the auto tire, the air stem is covered. You will need to remove the cap before you can insert air into the stem.

6. If required, you will need to increase or decrease the pressure in the tank to the correct PSI (7 to 10 lbs.). You can use a standard bike pump or a compressor. This is a low pressure system so be careful when inputting additional air as over inflation can damage the bladder.

7. Then open the tank valve followed by opening the incoming water valve.

8. Permit the tank to fill, depending on your RO membrane size, this may take a few hours. When filled, determine if the system now operates properly after you corrected the air pressure.
