ro problems

[kellymm7149]

I just swapped out all my filters in my 75 gpd 5 stage ro-di unit the problem is I'm getting more filtered water than waste water I took the unit back apart to make sure none of the filters were being bypassed they all seem to be okay i'm still using the same size ro membrane it a filmtec 75gpd and my original flow restrictor anybody have any idea of whats going on ?

Make sure the o rings on the membrane are good and not out of place and seat the membrane down in the housing tightly. Thats a common problem.

If thats not it you only have 3 other options. One is a cracked or otherwise defective housing causing a bypass, second is the waste valve could be mis adjusted or bad and third is a defective membrane which does sometimes happen.
Thats your choices.
