Review on Red Kohler GP83064 2-Inch Toilet Flapper by Jason Rodman

This is a genuine Kohler GP84995 replacement valve. The packaging says it's for some Kohler one-piece toilets like the San Raphael and Rialto. I have a Kohler San Raphael toilet that was purchased in the 1990's and this product does not match older toilets of the same name. I later learned that older (circa 1990's) San Raphael and Rialto Kohler toilets required a different closure. The correct faucet for old Kohler one-piece toilets like the San Rapael and Rialto is Kohler. GP83064.
