Selecting the wrong RV toilet paper can cause backups and malfunctioning sensors in your unit’s black water tank. It is important to keep in mind that just because the packaging says the toilet paper is “septic safe” and that it “easily breaks down” does not mean it is the best RV toilet paper for your unit.

There are a variety of RV toilet paper options available, including Scott’s Rapid Dissolve for RVs and Boats and other brands that make toilet paper specific for RV travel. These are designed to break down faster and easier, causing less problems in the black water tank of your RV.

The same thing goes for paper towels. Many paper towels are designed to not break down when wet, which means they will not break down when flushed down into the black water tank.

A simple water test of popular brands and some not-so-popular brands shows which the best RV toilet paper available is. This test looked to see which brand dissolved the best. Here are some of those results:

  • RV-Marina by Thedford is predominate in RV industry, makes sanitizers and cleaners, and broke down well with no big clumps.
  • Scotts RV toilet paper was fast dissolving and broke down well with no clumps.
  • Quilted Northern said it was septic safe, but did not breakdown at all which could cause problems sticking to sidewall.
  • Bargain Brand said it was good for septic systems did break down a little bit but not enough and could still block sensors.

When selecting an RV toilet paper get those that rated for RV use. This will ensure there are no problems with clogging of tanks or valves and will ensure the monitor panel read correctly.
