Black Tank Chemicals for High Temperatures

When we are traveling, I empty the tank weekly. Since the sensors don't work, weekly seems to be fine for the 2 of us. All I can tell you is that when I tried to use just 2 ozs for a week, an odor would develop. With 4 ozs the week was fine. When traveling, I flush the tank regularly letting the flush go until the water is almost clear.

I plan to buy something and would really appreciate product recommendations. If you are happy with just using water. I'm not comfortable with that. We have been doing this since 2001 and have always used some sort of chemical.

I'm with others...if you are having odors (even in hot weather), you have a problem that should be addressed. I highly suspect that your Air Admittance Valve (AAV) is not operating properly. Typically you can find this valve under a sink (kit/bath) and should be replaced. It comes right off and you can find replacements at Home Depot or other hardware stores.

There are other culprits that provide tank odors to penetrate the interior of an rv, but the AAV is the most common. A plugged (or partially plugged) roof vent tube, poor seal on toilet flange, etc.

Adding chemicals is a band aid fix...and can get expensive. How much $$ do you think you have spent on toilet chemicals in the past 14 years??

Best to locate the problem and fix that before throwing your $$ down the toilet.

Good luck
