ro water

[shikhyung]

I replaced my RO membrane with the 75 gpd 2 moths ago. Recently, notice that each time I collect the water from the faucette, the water seems to have a lot of bubbles and cloudy for a few seconds, then clear. What is happening? Thanks, Shin.

Sounds like you are getting air entrainined in the system.

what should I do? Thanks, shin

[BuckeyeFS]

Is your resin housing only partially filled with water? Aire trapped in the system tends to get trapped in the DI housing. If so, bleed the air out.

With the system running, unsrew the DI housing about a quarter turn - just enough to break the seal at the oring at the top of the sump. You'll see the water level rise as the water displaces the trapped air. Just before the water level reaches the oring, cinch the housing closed. That's it.

Thanks Russ, to verify just make sure that this is from the RO out put, not the DI. Since the DI output is only 1/4 " hose, water comes out from there very slow, it's hard for me to detect that I have the same problem. Yes, it seems that I kind of have a lot pressure at the RO , each time I open the valve, it makes sounds like release air....Shin

Do you have a pressure tank?

[shikhyung]

I am not sure what is pressure tank, but my is an original 5 stage drinking water with the 3 gallons holding tank, then I added the Di stage at the same time I replaced the membrane to 75 gpd.

I'd need to inspect your system, but it sounds like you may have a leak in the bladder in your tank. Try taking the tank out of the system and see if you still have the same situation.

[shikhyung]

Ok, If the blader is leak, then what is the fix? Thanks.

[BuckeyeFS]

A new tank.
