How to Find Right Toilet for Not Clogging- The Buying Guide

Investing in a toilet is one critical design. All toilets look similar, but when it comes to performance and features, each has its own distinctive functionality. Therefore, it is essential to consider the following important factors before buying a no-clog toilet.

  • Different types of Flush system

The most important feature of a no-clog toilet is the powerful flushing system. Not only it helps to reduce clogging issues, but it also keeps the toilet clean for a long time. The two prime flushing systems are gravity flushing and pressure-assisted flushing systems.

A gravity flush system uses the pressure and weight of the water to push all the waste out of the toilet bowl and into the sewer line.

A pressure-assisted system utilizes compressed air to propel the water out of the bowl and tank, which results in powerful flushing. Such flush systems tend to clog less often as compared to the gravity flush system.

  • Flush Valve and Trapway size

The trapway and flush valve size are essential as they regulate the amount of solid and liquid waste that flows out of the toilet to sewer pipes. When the trapway of a toilet is larger in diameter, it helps in better flow capability. In simple words, it reduces the chances of clogging.

The same rules apply to the flush valve size. A flush valve is available in different sizes and ranges from 2 to 4 inches. In other words, the faster the water is delivered to the toilet bowl, the less likely it will clog. It gives 3 and4 inches flush valves a benefit in decreasing clogs.

  • Manufacturing Materials

The material of the toilet plays a significant part in the clogging issues. Most toilets are manufactured with ceramic material, which is a mix of silica and clay. A toilet featuring a trapway covered in enamel creates a smooth and sleek surface that allows waste and water to seamlessly flow out of them into the sewer line. It helps to prevent clogging issues.

  • Water Re-fill Time

Everyone wants to remove the water from the toilet in no time and then refill the toilet tank with freshwater quickly. A toilet that flushes and refills slowly is more prone to clogging. The reason is the little water pressure when the flushing procedure is activated.

Make sure the toilet tank refills in less than 2 minutes. If it takes more than 3 minutes to refill, there are more chances of clogging.

Why do your Toilet clog so often?

Why the toilet clogs often and who to prevent clogging are two things you need to know. Remember, all clogs can’t be prevented, but following some vital factors, you can reduce the chances of toilet clogging.

  • Toilet Paper Usage

If you are using excessive toilet paper, it may be the prime cause of toilet clogging. You should avoid using toilet paper as much or buy one-ply toilet paper.

  • Low Flow Toilets

The initial line of low-flow toilets wasn’t meant to provide a more powerful flush. The prime purpose of these toilets was to conserve water. Nowadays, toilets with powerful flushing mechanisms have replaced low-flow toilets.

If you have a low-flow toilet, there are maximum chances of clogging. It is better to replace such a toilet with a modern toilet with powerful flushing to prevent clogging.

  • Flushed objects

Another major reason for toilet clogging is flushing non-biodegradable objects down the toilet. Such items include hard paper, diapers, wet wipes, and sanitary or hygiene items that mostly result in clogging your toilet. Make sure to avoid flushing these objects.

  • Blocked Toilet Traps

If the toilet trap is blocked, it will create a clog once it is flushed. The trap is a U-shaped pipe that keeps sewer gases from entering through your toilet and also moves the content from the bowl out through the sewer line. Flushing toilet paper excessively or not flushing often proper can lead to a blocked trap.

likely to clog. Also, avoid throwing toilet paper and other waste on the toilet to prevent clogging issues.

Frequently Asked Questions (FAQs)
