Looks accurate to me...
Paul,That diagram looks accurate with what I have ingrained in my memory. Be sure and let us know how that Newport toilet works out. The one thing that keeps me from changing the toilet on our boat is the height. The seat height is fairly tall on our boat and I've noticed that most toilets are taller than the WC Headmate that we have. I'd rather not install something that is even taller than what we have.
