See picture below, we had a Sioux Chief 828 shower drain installed in our shower pan and the installer left off the rubber gasket, fiber gasket, and locking nut. He says the Polyurethane Sealant is enough. Then why would the manufacture (Sioux Chief) include the rubber gasket, fiber gasket, and locking nut? It doesn't appear typical to me, but is this normal to not use the gasket and locking nut?
Everything below the wedi Fundo Primo shower pan was NOT installed.
