This is the original toilet in my 2004 Hunter 36. I am not sure which model I have but the only issue I have is leaking water around the pump handle and it occasionally requires more than usual pumping to draw water into the bowl. In reading the numerous posts, I realize the WC is no longer made so I am not sure a maintenance kit is still available. I am interested in others opinions on the best course of action given the age, make, and availability of parts for this toilet.
