What is the Worst Toilet Paper for Plumbing in Septic Systems?

Three-ply and quilted toilet papers are the worst for plumbing in septic systems. They can cause serious plumbing problems and make you spend a lot on repairs. Three-ply or ultra-plush toilet rolls are also dangerous for septic systems. They don’t break down quickly, so they are likely to clog your toilet and damage your pipes.

Below are the worst types of toilet papers that you should avoid for your septic systems

Three-Ply Toilet Papers

Three-ply toilet papers are also known as “ultra-plush” toilet papers. They are the worst when it comes to disintegrating in water. You should avoid them at all costs if you have a septic system in your home.

Three-ply toilet papers hardly break down in the water. They come out soaked and thick, but almost 100% intact. They are sure to clog your toilet.

It is better to use three pieces of 1-ply toilet paper than to use one piece of 3-ply toilet paper. With one-ply washroom paper, the roll will still break down fast. But three-ply will remain almost the same and end up clogging your pipes. You can also check out this article that discusses why toilet paper is bad. We have shared tips and ideas that you can refer to.

Quilted Toilet Papers

Once you see a product with the description “quilted”,  avoid it because it’s not good for septic systems. Quilted or ultra-soft means the toilet paper is thick and will expand rather than disintegrate in the water. This can cause serious plumbing problems. You need toilet rolls that will degrade, and not expand. On the other hand, if you are okay with using quilted toilet paper, you can check out this Quilted Northern Toilet Paper. It is made to be super soft and absorbent for comfortable use. 

Scented Toilet Papers

Some of the high-end toilet papers out there are scented with certain oils. Some others contain softening agents and bleaches. While these toilet papers are usually very comfortable, the chemicals they contain can harm your septic system. Watch out against these types of toilet paper and avoid them.

The toilet paper types above are the worst of them all, but there are many other unsafe types out there. If you are not sure about a type of toilet paper, you can do a toilet paper test to see if it’s safe or not. The process is simple, easy, and takes no time.

How to Do the Toilet Paper Test for Septic Tanks

To do the toilet paper test for septic tanks, you will soak the toilet paper in water for about 15 to 20 minutes and see if it breaks down easily or not. If it dissolved well in water, then it should be safe for your septic system. But if it does not dissolve easily, it is unsafe and you should not use it. If you do, the toilet paper will clump up and cause a blockage in your pipes.

Here is a step-by-step guide on how to do the toilet paper test:

  • Place two sheets of toilet paper you’re testing in a clear glass container.
  • Add two cups of water to the container and leave it in place for 20 minutes.
  • After 20 minutes, stir the cup vigorously and see whether the paper will break down.

Vigorously stirring the toilet paper replicates how the toilet paper would fly down your plumbing pipes. If the toilet paper breaks down very well after stirring, then it is septic-safe. But if it does not break down well or, worse still, if it does not break down at all, it is not septic safe.

If the toilet paper does not dissolve, that’s a clear indication that it will not disintegrate when you flush it down the toilet. It is likely to clump up and clog your pipes as more toilet papers get stuck in the same place over time.

What is the Best Toilet Paper for Septic Tanks?

The best toilet papers for septic tanks are certified septic-safe toilet papers. These toilet papers dissolve quickly but they hold strong before you put them in water. The National Sanitation Foundation evaluates toilet papers and certifies those that are safe for septic systems. These usually include biodegradable and recycled toilet paper.

Easy disintegration is not the only criterion for septic-safe toilet paper. Septic-safe toilet papers must also hold together very well while using them. It is counter-productive if the paper doesn’t hold together because you will have to use several pieces. And these several pieces may not break down easily.
