It works but is too limited for the drain line of my reverse osmosis filter which is rated at 400 gallons per day at 100 pounds per Inlet 77 F square inch. My output ppm is too high when I use it, 190 ppm. I can get 07ppm with no limit and 35ppm by manually limiting with needle nose pliers while squeezing the drain tube.
