I have a similar problem Water running but no production at all, but not sure if the membrane is choked or there is too little pressure on the Main input line.
How long would it be until I see some product.
How can I measure that pressure and how do I determine if the membrane is "Finished". Unit was purchased used but the owner said it was never installed... Not true there was water inside. The lower chambers but none in the membrane chamber was dry. If a membrane dries out will it have problems? A
You need to check the pressure of the tank. turn off the water completely then empty all the water you can our of the tank. Check the PSI it should be 7-8 PSI when it is empty. Add pressure to it if it needs. Next turn on the system once again and let the tank fill up. When the tank is full it should have between 43-47 PSI
Reverse Osmosis systems function totally on pressure. In the reserve tank there is a bladder that has constant pressure on it. Once that fills up to a certain pressure (45-47 PSI) it pushes back on the supply and basically flips the switch so that no more water goes through the RO System. If water keeps going down the drain, that means that is just not enough pressure built up to let the System know to stop.
Make sure you don't have any leaks in any of the canisters or going up to the sink. That could be bad as well
