Super Clean mixture works wonders on removing crud in tanks. About a quart and fill the tank and let it set for 2-3 days minimum. The longer soak, they better.

My theory exactly.


I'm a little too truthful, I guess.

Clogged Holding Tanks

And be sure to buy yourself one o those handy dandy see-through elbows that connects to your sewer outflow. There are few things that give you a greater sense of power than seeing all those lumpy things rushing through your see-through elbow. Before I started using one, I had assumed my tanks were empty. Little did I realize how wrong I wuz until I was able to see what was exiting. Another blessing is the built in black tank rinse.

I had the same problem when I purchased my 2008 Sunseeker, tried the ice cube method it didn't work. In surfing the net, found the Geo Method, and after 2 treatments, started to see improvement in the sensor reading, by the 3rd treatment sensors were working correctly. Suggest you treat the black tank and the kitchen grey tank, the shower tank get's enough soap from showering to keep the sensors clean. Check out this site.

A rv seminar I attended recently recommended to use vinegar / water mixture. Maybe worth a Google sear. Presenter said been doing it for 3o yrs. I guess it's cheep. Will try it this season.

This is for Still Kickin,

Your Idea about cleaning the B G tanks has brought new light for me.
My RV has only 2000 miles on it and my black tank kept reading full when it was empty. Tried you approach and it works, thanks a bunch.

Sensors are always off, the best way is to use it and see how long you can go before dumping. I know that just the 2 of us I need to dump every 5th day for black and 3 days for gray if we use the shower or 4 days if we don't. Kitchen gray every 3 days.
