Yosh. This looks really clean. For clarification - does your chlorinator fill up with liquid chlorine as you have your injection tube at the top port? Do you still meter it with the valve system that you kept on the chlorinator? The reason I ask, is that I was considering 2 options
1) remove the puck holder body of the chlorinator, cap the top of the tee and just inject through the 1/2 port on the side of the tee body
2) leave the whole unit as you have done, but remove the metering tube, plug both ports on the puck holder body and just inject in the 1/2" port on side of the tee body.
I know you have to clean that puck body out real good so you do not have any residue from the solid pucks that would interact with the LC.
