When to dump?

Touché!!
Really, very good retort.

This is what you do:

Always keep a bag of frozen grean peas in your freezer. To check black tank level, fill toilet with about two cups water. Place 10 frozen (important that they are frozen) in the toilet and close the lid. Quickly exit the pod and open the black tank flush cap on the side of the pod. Count to 20.

Now, re-enter the pod, open the toilet lid and count the number of peas that have sunk. That will tell you exactly how full your tank is. Five peas sank - 50% full. Eight peas sank - 80% full. Two peas sank - 20% full.

You can use fresh peas, but you will have to count to 45, instead of 20.

Hope that helps!

BTW, I learned this method after my first unsuccessful night of snipe hunting. They told me to hold the burlap bag on the trail and call, "Here Snipe, Here Snipe". Didn't catch anything.

Next time you see frozen peas in the freezer, you will remember this. Come to think of it, I wonder if it will work with my septic system.

Cheers!

Yup, when you see the black water rising up towards the toilet you are at the end.  You might get one more flush.  The gray water tank is full when the shower pan starts to fill up.  Every camper I've owned, the sensors were useless on the black tank, and only somewhat useful for the gray and fresh tanks.

The wall panel sensor is not useless, just not precise. If you look at where the sensors are located on the tank, there is not much vertical space between the low and high sensors. The same thing goes for the fresh and gray water tanks.  Full is only relatively full. There is additional space. However, if it is reading full, that would be a good time to dump before it reaches so high the toilet can't flush.

Keeping the black and gray water tanks cleaned out seems to be the best way to keep the sensors operating. If there is a build-up in one of the the tanks, it might cover the sensors to the extent that they can't detect the liquid levels. The fresh water tank is, of course, not (at least, it better not be) affected by this problem.

There is no alarm to alert when the tank is full and in danger of overflowing. One must monitor the tanks. Adding an alarm might be a good mod to make if someone knows how to do it. I don't, so I will just monitor the levels.

The Pea Pee Pod? Poo Pod? YUK.
