RO filter

Is my RO filter junk?

Here are images of tap water and RO before DI filter.

Is this new ? Have you changed the filters in the RO ??

Tap 250 and after ro 106? If so, I’d say new membrane needed.

Sure your not testing waist water from your membrane?

Measured from here.

Look how fast my DI is getting used. Only 4 days!

 

[DraggingTail]

And after DI I'm good.

Your ro doesn’t have some sort of alkalinity enhancer for drinking water does it?

I took stages 5 and 6 off. The 106 is right after the RO membrane on the pure water out

How old is membrane?

 

[DraggingTail]

They advertise that the RO membrane will remove 99%.

2 weeks

Are you flushing the membrane and letting it run a few minutes before testing? Your DI turns tan as it’s used up so It doesn’t look like you have burned through that much

 

[Retro Reefer]

For what it’s worth mine always puts out high TDS when I first start it up, I just run it and watch my TDS on the inline TDS meter on my system until it drops to around 5 ppm then I start collecting.

Seems like a lot 4 20 gallons running through it

Mine collect into a tank

Two questions.
If we can back up, is your rodi plumbed this way?

#2 are you on well water ?

 

[DraggingTail]

Red is water coming in from tap.

 

[DraggingTail]

After the bottom three stages the RO is on top.

This goes out to the DI (also where the 106 total dissolved solids reading came from)
