Selecting the Best Toilet Paper for Your RV's Waste System

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.

Inaccurate readings in your black water tank could be caused by using the wrong toilet paper. Now, a lot of people think if it says septic safe on the back of it that it's okay to use in an RV because it will breakdown and not cause a problem. But there's different levels of how these are gonna dissolve. Now, we went out and we bought a variety of different models here. So we have two of them that are actually recommended for RVs.

We've got the Scott Rapid Dissolve RV and Boats as well as the Thetford RV and Marine. And then we have just a regular household brand here which is the Quilted Northern, but it still says on the backside that it's a flushable and septic tank safe. And even our bargain brand here, this little 99 cent one. On the backside here, safe for standard septic systems. So a lot of people think that all these are good to use an RVs.

What we're gonna do is we've set up a simulated holding tank here, Blackwater tank. And we're gonna take a little bit of this toilet paper and we're gonna actually put them in, splash them around a little bit for a while, and then let them sit. And just see how well they dissolve over a period of time. So the first one we'll do is we'll take our bargain brand here, and just do a couple of tabs of that. We're gonna actually mark these.

So this one was, the bargain. We'll take our Thetford, Pampa-Chem. Cut the clean sheets here, we'll start right there. Put those in there, Thetford. The Quilted Northern.

All right. And we have our Scotts. And finally, I'm gonna just take a regular sheet of, paper towels, and show you what that's gonna do. We'll make it about the same size. So we'll just put that in.

And just put in, paper towel. So we're just gonna take and switch it around a little bit, simulated driving down the road. And then just kind of let it sit. We see a couple of these are already starting to disintegrate pretty fast. That's our Thetford.

Here's our Quilted Northern. And our Scotts. And then the paper towel. So what we're looking for is how fast they start to dissolve. The other thing I kind of noticed as I was pulling these apart that some were more a little thicker than others.

The thinner ones, you know, so maybe personal preference on the style that you want as well, compared to how this is gonna start to dissolve. So we're gonna let these sit but we'll come back periodically and take a look at them and let's see how they work. So last night we put different samples in the water in these mason jars and we let them sit overnight. So they've been in there for about 12 hours. These are the two RV-related ones.

This is the Northern Quilted. And this was the bargain brand and the paper towels. So we've got our Thetford RV Marine right here, Quilted Northern, Scott, bargain brand, and our regular paper towel. So we're just gonna see how well these fare. They're supposed to break down.

We don't want to have big clumps inside it. So they get onto the monitor panel probes and so forth. And we see this one, you know, typical with a paper towel that it is, they advertise they're not gonna break down in water. So we have quite a large clump here that is gonna not only give us false readings but it'll also probably clog our valves, maybe even clogging inside the pipe itself. So not a good idea to use paper towels at all.

Our bargain brand then is next. And even though it said it was good for septic, it still, we see quite a few larger clumps out of this. It did break down a little bit, but we still have some pretty good, you know, put it on the side. It's gonna sit up against the side of our holding tanks. It's gonna cover our monitor panel.

So probably not a good product to use in an RV. Then our Quilted Northern. Again, this one actually said right on it here that it is a flush able and septic safe for standard sewer and septic systems in here. And it didn't break down even as much as the bargain brand. So this one, we gonna have some problems with it.

Again, sticking to the sidewall, clogging valves, that type of stuff. So again, not a very good product to use in an RV. Now, we have our two Scott and our Thetford. And our Scott, actually says, RV and Boat and it's fast dissolving. And if we get a good shot of that we'll see that broke down really, really well.

I mean, there's no clumps in there. There's a few particles. You know, when I go to pull something up I have next to nothing in there. It's not gonna sit up against the sidewall. So that product performed excellent.

And then our Thetford product. And Thetford, this is a Camper-Chem. And Thetford is pretty predominant in the RV industry, they make a lot of toilets sanitizers, cleaners, that type of stuff. And so they've got the toilet paper and we can see too that that one broke down real well. Pull this out, we've got no big clumps, just small little particles.

If we can see inside there, it did really well. So for our example here, I would say even though it says it's septic safe that doesn't mean it's good for the RVs. Get the ones that are RV rated, that'll break down. You won't have problems with your monitor panel readings and you won't have problems with your valves.
