MY RO Readings......

[cm11599ps]

I've had a 5 Stage, 75 GPD BRS RO unit since October. I have the dual TDS meter before and after the DI and it reads about 8 in, 0 out.

This week I installed the 150 GPD upgrade and also put another TDS meter on the water into the RO unit and the waste line, just for S & G's.

PSI is 64
Source water is 74
Water Into DI is 2
Water After DI is 0
Waste Water is 120

Anyone else?

I have a Spectra Pure 3 stage 90 gpd RO with added DI.
Tap water 475-500ppm TDS
After RO 8ppm TDS
After DI 0ppm TDS
Waste water 250ppm TDS.
Oh PSI at the membrane is 80-82 psi.

I have the BRS 6 stage chloramine system with the 150 GPD upgrade (2nd membrame). I only have the dual TDS meter on the RO out and DI out so I don't know the TDS of my source or waste water.

50 psi at the RO membrame
After RO 1 - 2 ppm TDS
After DI 0 ppm TDS
1.67:1 waste to product ratio

I've produced about 600 gallons of purified water and have only used about half of my first DI cartridge. I've thought about getting the booster pump but I'm happy with the current performance.

Sounds like the unit is doing great.
