This article will guide you in following the water through your Reverse Osmosis system to determine where the problem area is, and how to fix it.
If there is no product water from the faucet, lift the storage tank up and determine if is:
Tank is Full of Water
1. Push the Schrader valve in on the side of tank. If there is water leaking from the valve, the bladder is broken and needs replacing.
2. Restore the air charge in the tank – empty the tank and use bike pump attachment to pump air into the unit to reseat the O-ring. The tank should hold 4-7 psi when it is completely empty.
Tank is Empty of Water
1. Is the absence of product water directly following a filter change?
a. YES; system is airlocked – remove all filters and reattach in reverse order, begin with Post filter.
b. NO; continue on.
2. Check the tank pressure – should be 4-7 psi when it is completely empty.
3. Test the incoming feed line is clear by pushing the Prefilter poppet stem. Warning: water may spray out during this test. If no water here, check feed line and supply shut-off if applicable.
4. Check ages of filters. Test Prefilter by pushing the Membrane poppet.
5. If no water here, swap Pre/Post filters and test membrane poppet again. If there is a spray, the Prefilter needs replacing. If there is still no spray, replace the Diaphragm.
6. Test the Membrane by removing the yellow line and watch for consistent water production. If no production, check Flow Control insert.
7. If constantly draining, test the TDS:
a. 75% or better reduction – check the Automatic Shutoff and replace if necessary.
b. Less than 75% reduction – check the Check Valve and replace if necessary.
