tank guages

[RollingDownTheHighway]

We just got back from VA and at the CG, my gauges for my tanks read empty, when we got home, I hit the tank buttons again and now they read
galley: 1/3
black: 1/2
gray: 1/3
fresh: empty

has anyone else experienced this with their tanks and is this something I should get checked when I get it winterized this fall?

Yup that is just part of the tank probe problems. You dump but there is still some crud in the bottom of the tank. When you are driving the crud splashes up on the sensors in the tank and then drys there. Only way to fix it is to flush the tanks but it will return. Just do a real good flush job just prior to hitting the road.

The tank gauges are known for not being accurate "stuff" sticks to the sensors.... After a while you can judge & get an idea of how long a tank can go before emptying...... or you can replace the sensors with a better quality brand.... I don't worry about them too much.

For the black water tank when finished draining and flushing add some water couple gals then add a bunch of Ice cubes down the stool and drive home or to you next destination. dump should cure. I've done this several times and cleared right up. Later RJD

That's kind of my thought as well, I was curious if others ran into something similar.

I run the black tank flush on the morning we leave for about an hour or so and then about 45 minutes before we hook up and role.


As some suggested, I'm going to dump ice cubes down the tank before leaving for our next trip to loosen up the black tank especially.

A search here on the Geo method for maintaining tank sensor health would be worth your time.

A product like Unique's RV-DIGEST-IT or Rid-X septic tank treatment will do a MUCH better job of cleaning your black tank than "ice cubes" which is a "hit or miss" operation. In fact the entire idea has been "debunked" and there is a video floating around that says why it does not work very well.

Follow the directions on the container and let it soak for at least 72 hours; more is better.

If it is still horrible, a sensor upgrade to "Horst Probes" might be worthwhile.
