5 Reasons Your Toilet Keeps Clogging and How to Solve the Issue

Clogged toilets are among the most frustrating household inconveniences you can possibly encounter. You might run into an unexpected blockage during a busy morning or find yourself dealing with slow drainage that worsens over time. Whatever the circumstances, a clogged toilet can disrupt your daily routine and cause unnecessary stress. What many people don't realise is that these clogs can occur for a variety of reasons—some more surprising than others.

In this post, we’ll explore some of the most common reasons toilets clog frequently and what you can do to fix these issues. Once you understand the root causes of this common problem, you can take proactive steps to keep your toilet—and your household—in prime condition.

Flushing Non-Flushable Items

It’s easy to assume that anything you flush down the toilet will simply disappear. However, toilets are not designed to handle everything that people might think of tossing into them. Items like wet wipes (even those marketed as “flushable”), paper towels, feminine hygiene products, and excessive amounts of toilet paper can quickly lead to a blocked drain.

Fortunately, the solution to this problem is both simple and effective: only flush human waste and toilet paper. Dispose of everything else in a waste bin; if you don’t have one already, consider setting one up right next to your toilet to help build the habit. With this small change alone, you can significantly reduce the likelihood of a clogged toilet and save yourself from the inconvenience and potential damage that improper flushing can cause.

Low-Flow Toilet Issues

Low-flow toilets were originally invented to conserve water, which is commendable in principle. However, older models may not have the necessary flushing power to clear waste effectively. This can result in chronic clogs that frustrate users and lead to more frequent plumbing issues.

One option is to upgrade to a modern low-flow toilet with improved flushing capabilities. These newer models are designed to save water without compromising on power. Alternatively, you can try to mitigate the issue by flushing more frequently during use, which can help clear the bowl more effectively. If clogs persist, it might be best to get a replacement to avoid further complications.

Blocked Toilet Trap

Often hidden from view, the toilet trap is a curved section of the toilet’s porcelain fixture designed to prevent sewer gases from entering your home. However, it can also become a prime spot for clogs. Objects like hair, small debris, or even accumulated toilet paper can get lodged in this bend, leading to frequent and stubborn blockages.

A toilet auger or plunger is often your best bet for tackling this issue, as these tools are designed to clear blockages in the trap effectively. If clogs aren’t cleared, take that as a signal to call in a plumber. Persistent blockages can indicate a deeper underlying cause that requires expert attention, so bringing in professional assistance is the best thing you can do to get your toilet functional again.

Sewer Line Clogs

A clog in the main sewer line is one of the more serious issues that can affect not just your toilet but all the drains in your home. These clogs can have a variety of causes, including tree roots infiltrating the pipes, grease buildup, or even debris that has made its way into the sewer line. When this happens, water may back up in multiple drains and cause a widespread plumbing problem.

You need professional intervention to address a sewer line clog. A plumber can perform a thorough inspection using a camera to pinpoint the exact location and cause of the blockage. From there, they may use high-pressure water jets or other specialised equipment to clear the obstruction. In severe cases, they may need to repair or replace a section of the sewer line.

Improper Plumbing Venting

Proper venting is crucial to the functionality of your plumbing system, yet it’s often overlooked. Pipes need air in them to keep waste flowing smoothly and prevent pressure imbalances that could lead to clogs. Thus, blocked or improperly installed vents can result in sluggish drainage or frequent blockages.

If you suspect venting issues in your plumbing, call a professional plumber to assess the situation. They can identify and clear any blockages in the venting system or correct improper installations. Proper venting not only helps prevent clogs but also contributes to the overall health of your plumbing system.

The proactive steps you take to address the causes of frequent toilet clogs can save you from the inconvenience and potential damage that comes with recurring plumbing problems.
