Worst Toilet Papers For Septic Tanks

This will enable you to know the exact types of toilet paper to avoid, the ones that will be beneficial to you, and your pocket will thank you for it.

1. Quilted Toilet Paper

The problem with quilted toilet paper is that they do not quickly disintegrate. Instead, they expand.

Why is this a problem? 

Toilet paper expanding in the septic tank poses a severe problem as its inability to disintegrate causes them to clog the tanks, thereby leading to some very urgent plumbing intervention.

Thankfully, you can quickly identify quilted toilet paper types by the bold inscription  “quilted” on them. Quilted or ultra-soft toilet papers are usually too thick, which explains why they swell instead of breaking down.

2. Scented Toilet Paper

We acknowledge the many fancy features scented toilet papers come with, but the fact remains that they are not for you if you have a septic system in your home. Some of these features include certain oils, bleaching, and softening properties that they are produced with.

While they may look quite enticing due to the built-in features and feel very comfortable to use, you should know that the downsides to using them far outweigh whatever comfort you experience.

The different chemicals used in producing these scented toilet papers are not, in the least, compatible with septic systems. To avoid a disruption in the proper functioning of your septic systems, keep away from using this toilet paper.

3. Flushable Wipes

Ideally, these are not even classified as toilet papers, but we still see a lot of people using them because they are, well, flushable.

Even though flushable, they hardly ever break down, thereby leading to clogs in the drainpipe, the septic tank, or right there in your toilet.

Asides from that, their continuous expansion in the septic tank will negatively affect the bacteria’s within it, responsible for the quick decomposition of waste.

4. Colored Toilet Paper

Forget about how attractive these toilet papers are and focus instead on the potential damage they will cause to your septic system.

The dyeing process of this toilet paper involves the use of unsuitable chemicals for your septic tanks. They directly affect the bacteria in your septic tank and render them ineffective.

5. Thick Toilet Papers

The logic to this is pretty simple; the thicker the ply is, the more resistance it puts up in degrading. This happens due to the properties used to make them appear wide.

For instance, the glue used in holding the layers in place alongside other chemicals makes them extremely difficult to decompose.

The same logic applies to soft toilet papers. Confusing right?

Actually, the chemicals equally used in making these toilet papers ultra soft are still unfavorable for your septic tanks. They make them overly challenging to break down. Constant use of this toilet paper will lead to— damage to your septic system.

6. Triple-Ply Toilet Paper

This might come last on our list, but it is the most problematic toilet paper homeowners with septic systems must avoid.

The scary thing about this toilet paper that rightly makes them earn this title is that they hardly ever disintegrate no matter how long they stay in the water. They only get soaked but still maintain their thickness and form almost a hundred percent. The result is the fast clogging of your toilet.

To this end, triple-ply or toilet paper with the description “ultra plush” must be avoided by all homeowners with septic systems.
