1

Feed water blocked and Low feed pressure |
Make sure all lines to the RO system and within the RO head are not obstructed. Low water pressure result in slightly higher tds than the 10%.
|
Untangles the lines
|

2
|
Wrong membrane direction |

3
|
Forgot to insert membrane
|
Normally without the membrane, the RO water's ppm is equivalent to the Tap water's ppm. |
