Review on Cherne 269905 Kwik Sure Mechanical by Elmito Yeager

I had to put some lines in my pool to check the plumbing. The pool is full of water, unfortunately this plug has a sign on it with some information. The tag is quite small and the font is clearly even smaller. One piece of information on the label was to use the plug in a clean, dry place. So this product is useless for me.
