Q: My ro system is producing a very thin stream of water and after about 4 cups, no water at all. I have replaced the cartridges within the last 90 days so I'm pretty sure it's the tank. A few years ago I had to put air in it, like a bike tire, to a certain psi but I can't remember what that magic number is or what the procedure is for valves open vs closed, tap on or off, that sort of thing. Thank you!
A: REPRESSURIZING R/O HOLDING TANKS
1. Shut off feed water to system.
2. Open (flip up) lever on R/O faucet.
3. Apply air (using bicycle pump, air tank, or air compressor) to holding tank at air valve.
4. Water will flow out of faucet. Stop applying air when water flow stops.
5. Check air pressure with low air pressure gauge. Correct pressure is 7-9 lbs.
6. Shut off lever at faucet and turn on feed water to system.
7. Allow tank to re-fill water. If problem continues after following these steps, call (317) 272-3000 or 800-447-5582 for further assistance.
