Re: Holding tank problem easily solved...
I HATE head odors.
If we we unable to pump out after a weekend the odor from the holding tank the next weekend was terrible. We had used all kinds of treatments but none really worked. I tried what we use for our home septic system last season. Septi-blast.
Odors are gone! I even let it go for 3 weeks as a test. No smell.
P.S. our head is fresh water flush
