I’m getting a Coast Guard Auxiliary inspection and the question of where the Y valve is came up—any idea s?
 
Steve:

I have an R29 but…the set-up should be similar. Find where your black water (sewage) tank is. Then follow the discharge hose and you will see a pump (macerator) and a y-valve. That valve has to be tied, zip-tied, or valve handle removed to prevent discharge of raw sewage in restricted areas. FYI - our black water tank is under the bed.
