What are your 2 resin chambers consisting of? DI changes colors. Polysidiment changes from white to brown. The other 2 carbon filters don't. How old are the filters? How old is the Membrane? What is the gpd on the RO? How many gallons have you pushed through it? And yes, backflush it and see if that helps some. If you haven't done it before, then its past due.
I am ignorant when it comes to this stuff. I'm assuming my resin chambers have di resin in them? No idea...it came dark brown. The unit was new in January, it's a 150GPD and I have put about 100 - 150 gallons through it. The water going in is 561TDI, so it's pretty nasty.
How exactly do I back flush it? Do I just reverse the input / output? Do I back flush the resin area too or bypass that area?

I use a backflush kit. Its kinda easier than hooking up all the lines yourself. They are all color coded. DI resin thought was green in color. It came dark brown, must be something I haven't seen then. You don't backflush those. j
Just basically the membrane. If you can figure out how to get it reversed with the lines go for it then. Pretty basic, no worries. Yea, its overdue for a flush.:beerchug:
