In this recently un-earthed video, we see how the innovative company Zurn Industries performs toilet tests on their Zern 1.28 high-efficiency model to ANSI standards with miso (soybean) paste.
In this 50 second video, you can see how these tests are performed in a pair of ways:
- Z5655 Cased Miso Paste Test
- ~20 50 gram cased miso paste blobs, dropped into the toilet through a hole. This is followed by 4 scrunched up balls of toilet paper, 6 sheets each in length.
- Z5655 Jumbo Miso Paste Test
- One single, 250 gram tube-like form of miso paste is dropped into the toilet through a hole. This is again followed by 4 scrunched up balls of toilet paper, 6 sheets each in length.
There is no note on whether the toilet paper is single, double, or triple ply. Perhaps this is due in part to the age of the video, when at the time of its filming, people didn’t care as much about their tush. Personally, I’m glad that we don’t live in the dark ages anymore.
It’s worth noting that the cased test has the added benefit of being reusable, in up to 100 tests. This is great for the environment, as well as cost effective for the manufactures who are running the tests. Let’s hope that they are passing the savings onto us.
The test mentions that the average real-world encounter of solid waste shouldn’t exceed 250 grams (approximately 0.5lbs), which goes back to a study by the NIH in 1978. However, more recently the US Environmental Protection Agency has adopted 350g of the soybean paste as the minimum performance threshold for “high efficiency” toilets.
