Unit is 2 months old. Drain line is flowing fine. If the membrane was blown then I should not get 000 readings out going. I even tried popping out the incoming meter that reads 300 normally and putting it in the outgoing water and it reads 000. So, I think the meters are accurate.

I have put LFS RO/DI in my container and I have put my RO/DI in a different container and I will test them after sitting overnight. I know measured TDS can increase with temperature but do ya'll think storing it in the garage could create a problem?
