Green is the color it should be when producing GOOD (low TDS) water. A constant Red light indicates the TDS is high (relative to what the normal TDS rejection is on your water supply) and the membrane needs to be replaced. Frequently the TDS light will be RED when initially drawing water at the RO faucet because of a spike of TDS coming through membrane from static water in line. I suggest taking a sample of pretreated water and RO water to a dealer for a TDS test to see if the Membrane needs replacing. RJ
