rodi
 

i got a used rodi unit from work and at the last filter which is labelled post carbon filter theres a tee to either go in the filter or to the storage tank wtf? and the storage tank only has the one entrance. so itll fill.the reason i ask is because some fittings were broken and it was all there so kinda re building it.

The final line should go to a T then one goes to the storage tank and the other is your output. Water goes in and out of the same line from the storage tank.

That's what I thought thank you!
