spiff72 Posted January 4, 2011 Report Share Posted January 4, 2011 Hey everyone. I am trying to understand the plumbing code requirement for traps that states: "Each fixture trap shall have a liquid seal of not less than 2" and not more than 4", or deeper for special designs relating to accessible fixtures." Can someone confirm for me that the attached image would violate the 4" maximum requirement, provided that this isn't a "special design" for accessibility? I just want to make sure I am not misinterpreting the code. It seems like they should have just cut off some of the tube at the bottom of the drain tailpiece, and they could have eliminated the metal bend and the short PVC extension piece. (Those joints are all underwater and could easily leak!) Thanks! Click to Enlarge 24.43 KB Quote Link to comment Share on other sites More sharing options...
hausdok Posted January 4, 2011 Report Share Posted January 4, 2011 Hi, It looks like you have a liquid seal of about 10 inches. ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...

So technically this is a code violation, then? (And possibly a common sense violation?) Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted January 5, 2011 Report Share Posted January 5, 2011 It's wrong......The issue is that the trap will not scour as well. Quote Link to comment Share on other sites More sharing options...
