If you use an enzyme tank treatment…..

You are supposed to leave a bit of liquid, AND " solids" in the black tank.

Although…I use enzymes and never have seen evidence of any solids or tissue paper. ( unless I have just " used " the toilet.)

Thanks for the link tip. I watched and it definitely makes sense. We are relatively new to Airstreaming so these sorts of discussions are very helpful.
Hope to meet you at one of the Ontario events.

We never leave the black tank dry, even in storage. I either leave the flusher running for a minute after closing the dump valve or use water from the fresh tank to get the black tank reading up to 15% and add tank treatment.

I leave the gray tank empty, and travel with fresh water full. The fridge and freezer as full as needed given the length of trip.

The other issue which may be of value to consider is chemical treatment that does not use formaldehyde in the formula. We have been asked not to dump if we had formaldehyde in our treatment. We have also seen the requirement mentioned in park rules.

We have several types of black tank treatment and you have to look for a formaldehyde free reference on the package. The grey tank treatment seems easier to find.

There is also a perspective pitched by some boat owners. The concept is that a natural approach does not kill valuable bacteria that breaks down the waste. Worth understanding if that is an approach that works for your lifestyle.

Whatever your approach, if you have a water supply, dilution can be a valid solution. If you do not have water, the solutions require more care and feeding, but are worth the effort to investigate and understand good practices.

Travel safe. Pat

Yep, many travelers do the ice, I believe it should help keep in sensor probs clean as well.

We always dump our black tank prior to leaving a site then add two or three gallons of water along with one or two of those dishwasher tabs (the ones with "spot free rinse")... One we get to our new site,, I'll add some more water, usually to half or more full and dump again. Add a gallon and some tank treatment and we're ready to go.

The dishwasher tabs really do a good job in cleaning the tanks while driving, more so than with the tank treatments alone.

I always prep my black tank after I empty and clean it. My ritual is 15 seconds flush water down. I add one scope of Happy Camper Treatment then another 15 seconds flushing. I am not sure how many gallons that is. It has worked for me. I store it that way. When I travel, I am always ready to go.

After a good dump and cleaning of both my black and gray tanks I add a little water and my tank treatment. I believe it is important to also treat the gray tank as it can be a source of some nasty smells.
