What is everyone using to cap the ends of the salt chlorinator unions ? I’m left with the female threaded part that I’m trying to find a male plug for but 2” is too small, tried 2.5” and it’s still barely too small. Only thing I can get to maybe work is tape it off and put a fernco 3” cap on the outside of the female threaded Union. Surely someone makes a plug for these chorinators. Also have a zinc anode that’s the same size I need to cap.
