caryseidner Posted January 15, 2009 Report Share Posted January 15, 2009 This has bugged me for a while, but I finally was able to snap a couple of good photos that (I think) illustrate my question. Here is a P-Trap beneath a pedestal sink, or is it an S-Trap? Clearly this pipe moves in an S shape. How long does the horizontal portion, directly downstream of the 'P', have to be to make it a 'P' and not an 'S'. Or is that not the criteria?
