Sure was. Got tied up cleaning and refilling the reactor. But there was no gasket anywhere for the lower portion. I was at my lfs and they had refillable canisters for 5 bucks so I picked up another and it had no gasket at the bottom. That leads me to believe there is no gasket for the bottom. Anyway I watched my other sediment filter in action and think it is supposed to come out the side, fill the container, then flow up from the bottom and into the next chamber. Not sure so I packed it full of carbon and let it go. Started filling my RO/Di and after about 20 gallons there was no changes in resin color. I may be good for now.
