I just changed my filters on my typhoon ro/di unit and im getting better readings out of my waste line? I have had it for two years now and this is the first time this has happen? The reason why i tested it cause i was at first getting an 37ppm out the di line and was getting 5pmm out of the waste line. Now im getting 07ppm out the di line and still getting 5pmm still out of the waste line. Any thoughts?
