Washing machine p trap question.
I see many comments about the washer p trap being requred on the same floor as the machine. We are in NJ and covered under the 2oo6 National Standard plumbing code. In that code I can find no requirement for the same floor. Simply 2 “ minimum standpipe size no more than 48 nor less than 18†above it’s trap.
The washer I have requires 24 to 36 above the floor with “the lower height preferable.â€
The reason I ask is I can mount the trap directly below the floor, have crawl space access as well as simplifying horizontal drain line to main stack. It will also tremendously simplify vent line.
So I could use a 30 or so standpipe above the floor to meet washer requirement and then the trap would be just inches below that, well with the NJ code length and even within well within other code’s lengths.
Do you see any problems with that? Is the reasoning of the code requirement in orther codes on same floor simply because of standpipe excess length issues, . Without that requirement in NJ, are there any other issues to think about?
Local jurisdiction has no modifications to code
