And for God's sake don't put in that "odorsafe" hose. It is junk. I just replaced the 6 yr old Odorsafe with the Shields original stuff. When I took out the original 1979 hose it wasn't because it smelled. It had just calcified to the point that I couldn't flush thru it any more. Within 3 years I could smell the sewage thru the Odorsafe stuff.

Never again.
