Decent test but these weren't sold as unisex urinals and the trapways aren't as big as they seem. They are more in the 1 1/4" tp 1 1/2" range. The real women's urinals had traps as big as a commercial toilet. About 2 1/4".
Thanks for the clarification. Perhaps these are used for men in wheelchairs, particularly I would assume these were for hospitals, although the three Derries I found were in general public facilities. Quite interesting that women’s urinals have the same trapway size as a regular toilet, I did notice on the Briggs women’s urinal I filmed did have a large trapway.
@@MajesticBaldEagle96 They're made for high traffic areas. At least from what I've seen of AS Jetbrooks and Eljer Terminals which are the competitors of these
