Hello everyone. I’m starting up a new tank and replaced the filter cartridges as well as the membrane on my RO buddy. After running the two cartridges I installed the membrane. I then ran that for 30 minutes as instructed before installing the DI component. My water is coming back around 30 ppm. Our tap water measured at about 150 ppm. I suspect the membrane is faulty and I plan to check the water coming out of the membrane without the DI component. My question is what ppm should I expect from just the membrane without the DI? Also if the membrane is faulty, do you think my DI resin is shot after being used with unclean water? I probably made around 2 gallons by now with the DI installed.
