I did try the gasket paper but I could not get it to seal tight. It started dripping. The gasket that was on the bowl was a black plastic ring. It has a screen but it did not seem to be attached to the gasket.
Although the gasket was very broken up. The screen has the little square hole in it. When I took the bowl apart the black ring just fell in pieces but the screen stayed in. Took the screen out cleaned it put it back then added my gasket paper. The bowl filled but then started dripping.
I figure I will give the cork a try. If that does not work I will have to order the plastic/rubber one. Mine was so bad I could not tell you what it was made of.
