PROCEDURE FOR RECHARGING STORAGE TANK WITH AIR
Product Description
PROBLEMS
1 When you turn on the spigot you noticed small water pressure from the storage tank.
2 When you turn on the spigot, only a quick burst of water come out of the system, and it dies down to trickles.
3 When you turn on the spigot in the morning, you only can get less than a gallon of water.
If you have the above problems, you should recharge the tank, because the storage should contain about 7 psi of compressed air inside the tank. The storage tank has a water bladder inside, and it is surrounded by compressed air. So when you turn on the spigot, the compressed air would squeeze or compress the water bladder to force the water out of the tank. When the tank is full the tank pressure can reach about 35 to 50 psi depending on your feed water pressure.
TOOLS NEEDED:
1 An air compressor or air pump (like a bicycle tire air pump)
2 An air pressure gauge that is able to read less than 10 psi
3 Adjustable wrench or 9/11" wrench
STEPS
1. Shut off the water supply to the RO system
2. Turn on the spigot to allow water to run until it stops (you can collect the water if you want)
3. Check to see if there is still water in the storage tank by lifting the tank. If the tank feels heavy, that means you need to recharge to tank and continue the following steps. If the tank feels light, that means you don’t need to charge your storage tank at this moment.
4. Locate the air valve on the side of the tank. It looks like the air valve on tires.
5. Use air compressor or air pump to pump air into the tank. Keep the spigot on while pumping air, so that all water inside the tank can be purged out.
6. After all water is been drained, use an air pressure gauge to check the tank pressure.
7. The tank should have 7 psi of pressure when it’s empty. Add or purge air if necessary.
8. Turn the feed water valve back on, and turn off the spigot to allow refilling of the tank.
9. finished
For a 5-Stage 50 GPD, it would take about 2.75 hours to fill the tank.
Note: If after few days of running the system, the problem comes back, then you may consider replacing the existing tank with a new tank (Item# TKE-3200W).
