What to Look Before Buying a No Clog Toilet

Suppose a toilet is an investment. And as with any investment, it is important as a customer to know what aspects and features make it worth the investment.

As a toilet, there is no difference in that. Here are a few points, you should definitely consider, during your search for the best no-clog toilet.

  • Flushing System

No doubt, the flushing system plays a crucial role, in reducing the potential of clogs. The two main flushing toilet systems are gravity systems and pressure-assisted flushing systems.

The gravity flush system uses the weight and pressure of water to push the waste and dirt out of the bowl and into your sewer line.

On the other hand, a pressure-assisted system use compressed air to propel the water out of the tank and bowl, which gives the stronger flush. Surprisingly these toilets clog less often than the gravity flush system.

  • Trapway Size and Flush Valve

The size of the flush valve and trapway is very important as they regulate the amount of solid and liquid waste that goes out of toilet through sewer pipes. Although when the size of trapway is larger in diameter, it allows better flow capability, resulting in reducing the chances of clogging.

The same goes for the flush valve size. The flush valve comes in many varieties and sizes, typically ranging anywhere from 2 to 4 inches. The faster the water is delivered to the bowl, the less the toilet is to clog. The larger valve gives an advantage in reducing the clog.

  • Water re-fill time

Well, if you really want your toilet to be clean and remove the waste, you need to re-fill with the freshwater as soon as possible. Toilets that re-fills slowly are more likely to get clogged. 

And if your toilet takes over 3 minutes to refill, then this can be the cause of the clog issue.

  • Material

This is not as important as other factors but the material that composes the toilet can play a minor role in clogging capability. Presently, most toilets are made of ceramic, a mixture of clay and silica.

However, a toilet with trapways covered in enamel creates a gentle and smooth surface, which allows water and waste to seamlessly flow out of them and into your sewer pipe. It results in clog prevention.
