I think there's a misunderstanding here so let me try again.
We currently have a 32.5 gallon black tank and not a 22 gallon tank. I guess I still have our old camper in my profile.
When we leave the campground we'll dump, we'll use the sewer flush, we'll close the dump valve to fill the tank with fresh water and dump again. We actually do this a few times. We have a clear connector so it's easy to see what's coming out of the black tank. Even after filling and dumping 2 tanks of fresh water you'll still see some tiny bits of debris coming out but the water is clear. We always try to keep our black tank as clean as possible and 4.5 years later everything still works well, including the tank meters. No issues there. Right after our last dump we'll put water into the black tank either by the sewer flush or the toilet itself for about 15 seconds and then drop in a tablet. That was when we leave the campground we only have a tiny bit of water in the tank along with a tablet.
The next time we go camping a few weeks later we'll have three people in the the camper. After about 3-4 days our 33 gallon black tank will be full by looking at both the meter and by looking directly down the toilet so we'll dump, run the sewer flush for a few minutes with dump valve open, then close the dump valve for a few minutes with the sewer flush on and then open the dump valve with the sewer flush still running. Once you can tell that the only water coming out is from the sewer flush then we'll close the dump valve, leave the sewer flush running for 20 seconds to get some water in the tank and then shut the sewer flush off before dropping another tablet down the toilet. That means there's only 2-3 gallons of fresh water in the black tank and about 3 days later it will be full again.
My gripe is not really about that. My gripe is about that last day when we really do a good cleaning of the black tank. We'll dump it but then it seems to take 15 minutes to fill up the black tank again whether it's by using the sewer flush or by simply standing on the foot pedal constantly.
I understand that in daily use you are adding more stuff down the toilet but the numbers just don't' seem to add up. In reality, how much liquid is going down when you do a #1? 2 cups of liquid?
