I have a 2001 410, I'm 3rd owner. Previous owner told me they usually used front head most of time and now I know why. When at pump out I can only remove about 1/2 of the contents. We do not put paper down bowl and in three years have only used for #1's.
When tank is 1/2 empty following pump outs we get absolutely no odors, when it becomes full of course we get some smell both outside and in. We have a Eco Vac electric toilet which appears to work very well. I have shot water into the vent from the outside and used a screwdriver to try and reach any blockage. I will try to remove the vent and as some have done on the forum drill a hole into the screen or soak in some lime away or white vinegar to eliminate any blockage. I notice when I pump the front head and flush with clean water for a rinse from the hose I actually hear a whistle sound from the vent due to the internal pressure from the water filling the tank . When I pump the back tank and flush until full I hear nothing and get barely a trickle if anything from the vent hole when the holding tanks becomes full with clean water to do a rinse? Any suggestions and thanks in advance.
