Rainbow 320 in-line chlorinator help???

Question

I went to refill my chlorinator with tabs this morning, I opened the lid and the o ring fell out.

Where does it go & how do I put it back in??

Answer 1

It should go around the top of the feeder, in a groove, just above the threads.

If the O Ring is old you should replace it. Use some silicon grease to lubricate it. Your pool store should have all that.

EDIT: The O ring goes in the cap, not on the barrel. The groove is there. The silicone lube for it is something like Vaseline and will help hold the O ring in place as well as make it seal better and last longer.
