I have the SWG Aqua Pure PCL 1400 Chlorinator and am trying to determine the caps for the ends if i remove the unit to clean with HCL. It would seem to be easier to clean with a capped end so one could fill the SWG with a 4/1 ration of HCL to water and let sit than try to find a bucket to fit the SWG unit into to soak. Anybody have any specification information about the end caps for the SWG Aqua Pure PCL 1400 Chlorinator. thanks
