I have heard more helpful hints and ideas and I’m always amazed at the creativity of RVers. At the same time I realized that some of the creativity is out of necessity or the knowledge and hint is because of a horrible experience. One such story came form a customer who was in my shop recently having to replace her holding tank because it was too clogged up. That’s right, remove and replace the holding tank. This is not a cheap fix, folks. 
Well, we all know that you need to use RV toilet paper and not the extra soft stuff. Wait. No one said anything about not using the Kleenex, or Cottonelle wipes or make-up removers and flushing them. After all, they do say, “flushable”, right? Wrong. That one little word, “flushable”, that my customer thought put them in the clear, in fact, did not. It likely contributed significantly to the mess of clogging they had. It cost them over $1,000 to replace their holding tank. What might be OK for the city sewer system is not necessarily OK for your RV’s septic system.
This was their first RV and, like the rest of us, wanted to have all of the conveniences of home. Unfortunately, that doesn’t include “flushable” products. They learned a tough lesson the expensive way. Don’t make the same mistake. You are much better erring on the side of safety and only using RV categorized toilet tissue. Trust us on this…it’s a messy and expensive lesson to learn.
