Michael Carson Posted April 13, 2010 Report Share Posted April 13, 2010 I have a client that is selling his home in another state and moving here. His buyer's inspector called out the S-Trap below. My client wants to know if it is something worth fighting. He writes "my understanding is if they have a trap arm length greater than 2 pipe diameters between the p-trap and vertical limb, then they really aren't S traps. The pipe diameter in the p-trap is 1.5 inches. The length of the trap arm is 3.5 inches. I believe the other inspector is right in that it is an S trap and should be fixed and what the client is talking about is trap arm lengths to vent. I just need some clarification/feedback before I answer. Thanks. Click to Enlarge 25.38 KB Click to Enlarge 32.5 KB Quote Link to comment Share on other sites More sharing options...
waynesoper Posted April 13, 2010 Report Share Posted April 13, 2010 I agree, not an s trap, that straight section would be long enough to prevent siphoning in my opinion Quote Link to comment Share on other sites More sharing options...
randynavarro Posted April 13, 2010 Report Share Posted April 13, 2010 It's not an s-trap but it's still wrong. The vent opening in the wall is below the weir of the trap. It must be above. Installing a longer tailpiece down from the sink will solve the problem. Quote Link to comment Share on other sites More sharing options...
Tom Raymond Posted April 13, 2010 Report Share Posted April 13, 2010 We can't tell from that pic if it is an S or not. The trap arm length references the distance to the vent, so if the arrow in the pic points to a Tee then it is a P trap and Randy is correct, but if it's an Ell then the buyer's HI is correct. Either way it's wrong. Click to Enlarge 28.55 KB Your client should be glad they only want the trap fixed. I'd want the hole in the wall repaired as well.

Jim Morrison Posted April 13, 2010 Report Share Posted April 13, 2010 Fight what? You should tell your client it's wrong and that he should write his buyer a check for a couple hundred bucks and get on with his life. Let the new buyer hire a real plumber to make it right. PS. Whenever I see a trap with no cleanout, I just know there's more trouble nearby. Quote Link to comment Share on other sites More sharing options...
