After 2 yrs. exp. w/my 1st AS, 25' Safari FB, I learned some lessons about waste management.
1. Don't let a pyramid build! Ask your guests to fill the bowl partially with water before flushing toilet paper.
2. Don't dump your black tank right after leaving your camp site. Driving a distance will agitate the tank preventing any blockage or build ups. It is much better to dump at the next campground. Fortunately my RV storage site has a dump with non-potable water flush.
3. I've used the Sewer Solution
SewerSolution from the start and would not trade it for anything. For the price and easy operation (clean) it can't be beat.
4. I highly recommend 3R ODOR-CON Product Overview . It is the best product on the market I've used to control black/grey holding tank odors. If used as directed you only need a single application per full tank and dumping. So it is much more economical as compared to all the other chemicals that merely mask the odors. 3R kills them by oxidation! If you can't find a dealer close by you can order direct from 3R. Try you like it.
