I am using a zmax v3 and an AGR tank. I know how to fill it correctly without forcing pressure into the carto. Im having leaking issues, suprisingly not from the carto flooding! Its leaking from in between the base and the locking base. I cant figure this thing out! Ive reassembled it multiple times and all the conections seem to be good and secure. Does anyone know what my problem is? Help please!!!
