Customer wanting to use the modern style sinks from Europe sold in IKEA stores. The drains make a hard 90 degree turn back just below the strainer and then go into a trap. I've not seen this arrangement before and they say they sell them all the time for new construction but I want to be sure they meet code. I do know several years ago there were problems with metric size piping that has been corrected so that is not an issue.
