Also, you should consider other features to ensure that you get the best toilet for your bathroom and people in the house.


How do I know that the toilet I am buying won’t have clogging problems?

Answer: So what’s the best toilet for avoiding clogs? 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 a large trapway, which minimize your annual water expenses. 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. So you don’t need to tap the flush button twice as one single flush for solid wastes is enough.

What flushing systems do no cog toilets use?

Answer: Even though there are several flushing systems on the market, some are known to be more exceptional and more 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 assist flushing system or a gravity-feed flush system. These two flushing systems are very efficient in performance and won’t let you down.

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.

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 a few drops of dish soap. These will help you to unclog the toilet.

  1. We bought the Woodbridge B0960S toilet based on the chart above. It gets clogged 3 times out of 4 it is used.

  2. What will be your recommendation for tall, seniors, or disabled people? My husband’s height is 6.5 feet, and he always feels uncomfortable with a standard toilet.

  3. My wife wants the toilet to be skirted for easy cleaning and insist on a lever flush as she hates the top push button on the tank.
    I would like to keep the price under $1000.00 dollars!
    P.S. her nickname for me is ClogZilla!!! 😂

  4. I’m looking for a very small toilet (max 26.5″ deep) with a 12″ rough-in that won’t clog. We had a Toto Drake installed about 5 years ago but it’s now unusable–can’t even flush toilet paper with clogging it! I’ve read all the good reviews of Toto–should I trust them again? Or is there another option?

  5. Hi could you please tell me which saniflo is the best on handling the odd cotton ball but is very low on noise level?

    You recommend the sanibest pro. Is this loud?
