This maybe where you'll find that Beavers are like snowflakes, each one a little different. On mine, removing many screws allowed me to fix water leaks and replace dump valves (fun!). One thing, if you find your leak is from a white reinforced flex hose, just replace the whole hose with a new one from Home Depot or wherever. They are called 'fixture supply' hoses and now have a stainless mesh on the exterior of the hose. Don't try to replace the 'Flair it' domed washers used in the white plastic hoses, just replace the whole hose.
