Won't keep the valves open, good to know. I heard some people leave the grey open and black closed? Should I just keep both closed?
We camp seasonally and keep the grey tank valves open (we have 2 black and 2 grey tanks). We are a family of 4. We fill the grey tanks very quickly. We'd be dumping probably 4 or 5 times a week. At our campground, each site has its own septic system. We may get a few sewer flies throughout the season. We have been on the same site for 4 years now.
