all good tips... so when I get to campground, regardless if I have a sewer site or not, is there a chemical that I add to both the black water and gray water tank? how is this chemical added? and do you re-add this said chemical everytime I flush the tank? also, when I leave, and I do like crimps says and flush and dump both lines, do I add more chemical to the black water holding tank when I get home and park the camper? im assuming that when I get home the tank will be fully empty, do I still keep some water in that tank while its sitting for a few weeks? and now the dumb question of the year, how does one dump a black water tank when not at campground? im talking end of year before winter when im cleaning everything, how do I clean out the black water tank at home?
Leave both tanks closed if only 3 days and not too many using toilet.
Yes, use a treatment which the place you buy it from should have ready for you. Dump on the way out. Close valves and flush toilet several times to add water and treatment and you are good to go for the next time. At the end of the year plan your last trip and dump there since you need to dispose of these liquids at a dump station. Our State Parks charge $3 for a dump, so we always fill with lots of water, and dump completely and leave them empty and then winterize since we are in WI.
