Question: How do I know that the toilet I am buying won’t have clogging problems?
Answer: One of the features to look out for in a no-clog toilet is the size of the flush valve and trapway. The best no-clog toilets usually feature a large flush valve and large trapway. Choose a toilet that has a large flush valve than the standard 2-inch flush valve. You should do the same for the trapway and select one that is larger than 2-1/8-inches. A larger trapway allows more mass to pass through it, while a large flush valve pushes water with a lot of force when compared to a standard one.

Question: What flushing systems do no cog toilets use?
Answer: Even though there are several flushing systems on the market, some are known to be exceptional and powerful than others. If you want the best flushing system that will prevent your toilet from clogging, then you should consider getting a toilet with either pressure-assisted or gravity-feed flush systems. These two flushing systems are very efficient in performance and won’t let you down.

Question: What causes toilets to clog?
Answer: Several things cause the toilet to clog, and these include excess tissue paper, kid’s toys, wipes, and even small balls. That’s why you have to be careful and always watch the toilet if you have kids around the house. If you see any peculiar item in the bowl, you should check it first before pushing it down the drain. This is the best way to prevent your toilet from clogging.

Question: How can I unclog my toilet?
Answer: The first step to take when you have a clogged toilet is to know what caused it to jam. One of the natural causes of toilet clogging is using too much tissue paper. If that’s the case, then you need to use a plunger to unclog the toilet. The plunger forms a lot of suction to assist in getting rid of the blockage. And if the plunger doesn’t clear the blockage, then you can try mixing a cup of baking soda and 2 cups of vinegar in your toilet. And if you don’t have baking soda and vinegar, then you can try out some few drops of dish soap. These will help you to unclog the toilet.
