I stumbled across an interesting YouTube video today that takes a look at the age old topic of pouring a bag of ice down the toilet.

From what I can tell, it helps but only a little. I hadn't thought of this before, but since ice floats, it really doesn't make contact with the solids at the bottom of the tank unless you drain the liquids first. I think the quantity and makeup of the ice would be big variables too.

The video is worth a watch though.

SENSITIVITY WARNING: There is no actual human waste in the video, but he uses simulated waste per a NASA testing recipe. Personally, I score this a 4 of 10 on the yucky scale. As much as we discuss tank maintenance on these forums, there shouldn't be anything we haven't already discussed here before. Nobody should be shocked.

I've heard that for years.

Was under the assumption that folks mainly used the ice when the gauge quit working and must be driving for it to be effective.

Personally have never tried it but do add a couple gallons of water and Dawn dish liquid after dumping the black tank.
It's been a very effective method for many years.

Same here: Water, Dawn, and some Calgon. The gauges have worked great since I started doing this a few years ago.

If I was going to try the ice technique I would go with very little water so the ice is sliding across the bottom of the tank. And I would not use bags of ice. Freeze water in 12 oz aluminum cans, tear the aluminum off and drop big chunks of ice down the toilet. Then go for a drive with lots of turns.

Might get some things loose from the bottom of the tank.

The "ice trick" is not meant to clean the bottom of the tank, it's meant to clean the sides of the tank. Not uncommon top have a piece of TP or similar hang up on a sensor and give you false readings. The ice bounces around the sides of the tank on the way down to the dump station and is supposed to clean off the sensors.

Google "The GEO Method" and read while you sip...[emoticon]

Just another "Gee Whiz" solution (no pun intended) that may or may not work.

I think that my sensor must have been installed directly under the drop shoot. Just a flush of water makes it read 3/4 full. Being that the sensor has always been inaccurate, I just use the sniff test to empty my black tank.

I must have had the same guy install my censor, lol. It hasn't moved off of 3/4 since i got it. If i cared i would install the new ones on the outside of the tank. A lot of people sware by them. Too much work for me.

Mine has been pretty accurate, but when I put 2 gallons of water in after dumping, it always shows 1/3.. I think they put the first sensor too low.
