I’m an architect in Sydney, and we currently have the problem of fitting a floor waste into and exisitng unit. We are trying to get away with as low a step into the bathroom, and I have been told of a New Zealand product which is a very low profile version of an s-trap. it’s apparently about 50mm, and consists of a baffle type arrangement rather than the traditional s bend. Can’t find this product anywhere, and no one knows what I’m talking about. Can anyone help????
I am not sure what Sydney allows, but in the states “S” traps are not allowed because they are self siphoning. A trap with a baffle is also illegal, since a hole in the baffle would defeat the purpose of the trap. And finally, the trap depth is regulated by its diameter and a low profile version might not have the proper seal depth.
