Black & Grey tank readings

Haven't looked at the monitors in years. We can tell when the tanks need to be emptied after being fulltime for so many years. They are never very accurate anyway.

We bought the Bigfoot TC from a rental place. I don't think renters knew how to dump properly. I put some automatic dishwasher detergent into both tanks, the kind made for a dishwasher not hand washing like Dawn, added 5 or 10 gallons of water, drove for about an hour and a half to campground, dumped on the way in, and at the end of the weekend, and the sensors seem to work reasonably well. I have since done this every year on the first trip out, to get rid of any crud that didn't get rinsed out from the previous years camping.

Hi,

It doesn't work. Ice sliding on a film of water is pretty darn close to a zero friction environment.

Google is your friend.

I have googled extensively and have not found anything that "debunks" the GEO method. The videos you posted have nothing to do with the GEO method and the method has absolutely nothing to do with ice cubes. Follow the link I included in my first post and actually read the process. It's basically a mixture of calgon water softener, detergents, and bleach in the appropriate proportions. It may not be effective, but I'd still like to see a scientific analysis similar to the tests performed in the videos you posted.

Would love a link. Not saying it works because as indicated, I haven't tried it myself, but all of the YouTube videos I've seen on it as well as forum posts seem positive for both odor control and sensor cleaning. I already have everything, so I do intend to try it on my next outing but that will be at least a couple of weeks away... If it doesn't work, I will have flushed about $6 down the toilet. Well technically, if it does work I will have still flushed about $6 down the toilet.

Hi.. this is my second 5th wheel and i never count on the sensors, to work.. I use a site tube on the sewage hose to determine if tanks are empty. Jim2007

Add us to the list of folks that have no problem getting our sensors to read accurately. We have a tornado flusher and use it religiously. Soaking is the best thing to do to clean out the black tank, and don't dump to soon after putting in toilet paper as it needs some time to dissolve.

Many people report great success with the GEO method. I haven't tried it yet, but I intend to on our next outing.
