run the unit and capture both the waste water and the "clean" permeate water
what is the ratio of these two volumes.... should be about 4:1
run the unit till you get about a cup of clean permeate and then measure the waste water volume
you will, water temp has a major influence on membrane efficiency...
when you remove your old filters, do you see signs of them being compressed and evidence of sealing aorund the central core?
Also...another strange thing...the new carbon blocks seem to work for the first couple of gallons after I install them, but after that chlorine shows up in the water...so they work at first.
I actually contacted the company that makes the RO unit, and even they were baffled.

well brine rate good, prefilters sealing good.... only things left are the prefilters themselves and the water
If you have a lowe's nearby, try getting your next prefilters there... they have a 3 filter kit of one sediment and two carbon block.
Ive used these for years with great service....
Using them would be using a known variable
FWIW The concentration of chlorine required by law in the United States is 0.2 ppm, the prefilter rating should be based on this level
Can you use an aquarium test kit and verify the household supply level?
Exo, your water company may be using Chloramine instead of Chlorine...
Typical carbon will still remove it only not as well, if that is the case you would be better off with something like this:
