Sometimes, the exterior components and fixtures of a toilet can be the easiest to understand. Things like the trapway size and bowl height are quite simple concepts, even for complete beginners. However, there are some things that inexperienced buyers miss when it comes to your toilets flushing performance. Forget what you know about single and dual flush, gravity and pressure assisted, there is data you can use to your advantage to determine how well a toilet handles waste.
This is known as MaP testing. This is a company run by a 3rd party that is used by leading toilet manufacturers to test out and give their products an official score based on the same set of criteria. It’s a fairer and more transparent way to determine a models overall quality.
Once they have conducted their tests, each product is given a score on a scale from zero to one thousand grams. They even give you recommendations based on their experience. Anything below 250g avoid at all costs. 350-250g is acceptable, but not something you should aim for. 600-250g is good enough for most households, and probably the category which most toilets fall into. And finally 1000-600g are top of the line options, and can remove waste from the bowl with ease.
A few examples of products with the highest rating on this scale include the American Standard Cadet 3 ADA (one-piece) 2403.048, American Standard Champion Pro 211BA.154, TOTO Carlyle II EL, TOTO Eco Drake, Kohler Adair EL K-6925 and the Kohler Memoirs K-3933U. All of which are less likely to get blocked up.
It’s important to remember this should be just one of many factors to look for when choosing a new toilet. Consumers should be keeping tabs on overall efficiency, tank style, bowl shape, and how noisy it is. They should also spend time sorting through the various customer reviews online to give a broader understanding of what buyers truly think about their purchases.
