Review on ❄️ Rubber Winterizing Expansion Plug 1.5" - Size 8 for Effective Cold Weather Protection by Mysocalled Gaultier

I started opening and closing my pool myself to save $600 a year. I empty lines with ShopVac. I use screw caps for the pool return and a squeeze bottle for the skimmer. I can't blow the floor drain properly so I blow through the filter as much as possible and then reverse the diverter valve so it closes completely. I then completely close the filter with this plug, since the diverter is not 100% tight. I also put one in the chlorinator for good measure. I think this is a good working solution. These plugs work fine.
