Rodi Suddenly Stopped
Hey guys my 4 stage just stopped filtering out the tds. The tap water is 37 and when it was working would drop it to 5. Now it's just reading 35-37.
I micron Sediment, 1 micron carbon, 5 micron gac carbon and then di resin is the order of the chambers. |

It's only been working for a month and only about 30 gallons have went through the entire system. I got one bucket with the normal 5 ppm then the next 3 buckets are reading up to 35-37 ppm. Even had one go through and come out at 42 which is dirtier than the tap water which is at 35-37 ppm.

Remove and reinstal the membrane.
Fwiw my ro takes 150tds down to 1tds. 37 to 5 is bad anyways. You should be 0tds with 37in. What kind of ro unit?

Ive read that some people recommend running a few gallons or ro through prior to di, increases the life of the membrane greatly. Just a thought.
