DH isn't very savvy on dumping the tanks but this is his first unit so I'll give him a break on that. What I have noticed is once the unit has been moved there is more waiting at the cap from the black water tank once its parked. The sensor shows its empty before leaving and this wasn't making sense to me even though DH says its reading empty.
Couple of days ago I dug out my old "blaster", not sure what they are called now but its a 4' long half inch diameter hose with a brass tip and 5 smaller holes at the end. You can hook it up to a regular hose or your tap, there is an adapter for it. Once you turn on the water there is a small lever you twist to "open" it and the spray is at a high velocity through the tips at the end, you can snake it down to the outlet if you want without damaging anything.
After hooking it up to a garden hose and leaving the black tank open with a bucket under it, I ran about a gallon of water down the tank then turned it off and ran around to see what was coming out...more stuff from the tank and not clear water. I waited and noticed the tank seemed to empty in waves so to speak, it would run, then just about stop then another batch would come out. Hmmm, something is clogging up along the line (and the unit is level) so I closed it off, went back inside and used my blaster listening and feeling how and where it was in the tank and line. There is a bend at one point about half way between the toilet and tank, I think that is where it tends to slow down when dumping then releases so you may think your tank is empty and it will read that way when there may be more which dislodges and you end up with black water at the cap.
I did this a few times with the same result: empty nicely, slow to a trickle and seem done, then wait and it will dump more until fully empty.
After a good blasting with the wand hose it now empties much smoother though there still seems to be that "slow" point when draining the tank so when you dump the black water, close it off, run some water in the toilet, open it again until you see the clear water. By that time it will be fully emptied and "clean", you can close the valve and know there isn't something that is going to be stuck anywhere between the toilet and valve.
Since I'm a bit "old school" I always make sure there is at least 1-2 gallons of just fresh water in the black holding tank at all times (except during freezing temperatures of course). It keeps bits of paper and stuff from sticking to the pipes and tank and you won't end up with a nasty surprise when you pull the cap to unhook after dumping all the tanks. Always make sure to dump the black water tank then your gray after, it also will keep the valve clean and closing properly. If you have a five gallon bucket, fill it with hot water and run that every 4th or 5th time after dumping the tanks, it really keeps them clean and nasty surprise free.
