Toilet Paper Coming Out Of Outside Drain (Explained!)

Toilet paper is manufactured to break and dissolve easily in water. However, if used in excess it forms a mass that is hard to flush and ends up clogging the toilet drain. So, why do I have toilet paper coming out of the outside drain?

Overflowing toilet paper from the outside drain is an indication of a blocked sewer pipe. When the sewer pipe is blocked, toilet paper floats. With the addition of water from the sink or shower, the tissues rise further and eventually overflows through the drain outside your house.

If the sewer blockage is inside your house or an area between your house and the septic tank, the overflow will happen through one of the traps outside the house.

On the other hand, if the blockage occurs along the main sewer pipe connecting different houses, the overflow will happen at the first house before the blockage. In this case, there will be a massive toilet paper overflow because the drain is serving many houses.

Irrespective of the scenario you are in, contact a plumber immediately you spot a toilet paper overflow from outside drains.

Why Toilet Paper Clogs A Sewer Line

As strange as it might sound, toilet paper can clog your toilet because some brands do not flush easily or if you flush too much of it.

If you cannot still understand how toilet paper can clog your toilet, below are a few reasons why toilet paper clogs toilets:

1. Flushing Too Much Toilet Paper At Once

It is true that toilet paper easily dissolves in water, but your pipes can only hold a certain amount and a block past that. Therefore, it is important to use just enough amount of tissue. If you have children in the house, teach them the right amounts of tissue paper to use.

2. Wrong Toilet Paper Brand

There are different types of toilet paper brands and some are difficult to dissolve than others. Many people go for the thick and soft brands, but this type is hard to dissolve and especially if used in large quantities.

What’s more, stay away from any toilet paper brand that contains lotion, because the grease will stick on the pipes causing a blockage.

The ideal type of toilet paper should easily break down into small pieces when immersed in water.

3. Drain Pipes With A Rough Interior

The interiors of pipes made from cast iron or concrete are mostly rough and end up snagging the toilet paper as it passes. Over time, the tissue paper collects in the pipes and causes a blockage.

4. Low Flush Toilets

Low flush toilets are designed to save water but work against the users because they block easily. Since they operate at low water pressure, there is a build-up of waste and tissue after every flush.

If you are using this type of toilet, make extra flushes from time to prevent waste build-up. Also, you might want to use a plumbing snake from time to time to get rid of any build-ups.

5. Narrow Drain Pipes

A plumbing system with narrow pipes clogs faster because the waste does not flow easily. If you just moved into the new house, and you are experiencing frequent blockages and overflows, contact a plumber for diagnosis and replacement.

There is no amount of prevention you will take to prevent blockages caused by narrow pipes. However, before the replacement is done, be mindful of the amount of tissue you are using and flush your toilet frequently to clear build-ups.

6. Flushable Wipes

For a long time, we have been encouraged not to flush wet wipes because they cause toilet blockage. However, recently, they came up with flushable wipes which were a relief to frequent wipe users.

Unfortunately, these flushable wipes are a major cause of toilet blockages because they are made of a thick material that does not dissolve in water. If your toilet has been operating smoothly until you introduced flushable wipes, it means that your plumbing system cannot handle the material, and it is safe to go back to using regular toilet paper or disposing of the used wet wipes in the bin.
