Green is algae bacteria, commonly known as moss. That is, the green plant pollen or spore reproduction after the product, generally have these substances appear, proving that the water has been contaminated, water purifier water can not drink directly, algae bacteria must meet the three conditions, one is the water contains plant spores, the second is the sun (photosynthesis) three is the temperature of 25 ° or so, in line with the above conditions will be produced. Water purifier faucet has these reasons there are several,

1: faucet around the flowers and plants, sun exposure, high temperature. 2: water purifier in the key parts have failed (such as ultrafiltration membrane failure or RO reverse osmosis membrane failure) in general the body of water with plant spores. You can do a test, with a glass cup of water on the windowsill location with sunlight, 3 days or so the water cup will be green.

Why the tap water will not have a similar situation, because the tap water has a residual chlorine, it can inhibit the reproduction of spores, but instead of the water purifier will be installed, because the water purifier which the activated carbon to the residual chlorine adsorption off. And ultrafiltration membrane, or reverse osmosis membrane failure and did not retain the spores in the water body, so it will grow moss in the outlet end.

It is recommended that you replace the water purifier and the outlet faucet, because contamination with algae bacteria is basically very difficult to remove completely.
