RV Toilet Paper Myths (And What Really Causes Clogs in Your Black Tank)

Think special RV toilet paper is the key to avoiding clogs? You’re not alone — but the real culprit may surprise you.

RV Toilet Paper Isn’t the Problem (Here’s the Myth)

Many RVers believe that using only RV-specific toilet paper is the secret to preventing black tank clogs. While RV toilet paper is marketed as quick-dissolving and "tank-safe," most standard septic-safe toilet papers dissolve just as well—if not better.

In fact, multiple toilet paper dissolve tests, including those from YouTube RVers and product reviewers, show that common brands like Scott 1000 perform just as well (or better) than many RV-labeled options. See our Complete Guide to RV Safe Toilet Paper.

What Actually Causes RV Toilet Clogs?

The biggest clogging problems in RV black tanks come not from toilet paper, but from poor flushing habits and tank mismanagement. Here’s what really causes trouble:

  • Not using enough water during flushes
  • Leaving the black tank valve open at a full hookup site
  • Letting waste dry out inside the tank (creating hard sludge)
  • Failing to deep clean the tank periodically
  • Over-relying on dry or thick paper without enough water

So while TP choice matters a little, it’s these habits that do the most damage.

Do You Ever Need RV Toilet Paper?

There are a few scenarios where using quick-dissolve RV toilet paper might help:

  • If you have a small black tank that’s emptied infrequently
  • When dry camping and water conservation is critical
  • If your sensors are particularly sensitive to any buildup

Even then, proper flushing and tank care matter more than paper type.

Conclusion: Don’t Blame the Toilet Paper
