I have had the Aquarite SWG for a few years. Last couple of years I used a winter rubber plug (I believe size #11) to cap off the cell to clean it. It worked perfectly.
Then I lost that rubber plug so this year I bought another winter plug, same size, but when I put it in the cell, water leaks out because the cell has a plastic ribbing that keeps the plug from sealing properly. I don't know why the original winter plug I had worked so great and this one doesn't.
I know they make stands to cap off the cell. I have heard that you can go to a hardware store and buy a PVC end cap that is supposed to work. I found a post by someone who tried it and it didn't work: "I tried going to Lowe's for an end cap, one they do not have one, as the T-Cell takes threads for a 1 1/2" union, not the smaller NSF threads of an end cap and the end cap would have to be a 2 1/2" end cap as a 2" end cap is too small and they do not make a 2 1/2" end cap. The 1 1/2" union fit well, except the o-ring part of the union is on the male threaded part, not the female."
So, I was wondering is everyone using the Aquarite propriety stand, or have you found something else that works?
