Review: The product fits great, I like it. I just want to suggest that it would be even better if it is wrapped with plumber's tape. When I got it, it fits fine, but it has tiny leaks. So I asked around, and people told me that I have to wrap it with plumber's tape. That resolves the problem. But it would be great if the product already had plumber's tape wrapped around it so I don't have to rush into canadian tire to get one.
