I am not guessing at anything. If my nose fails to smell anything untoward it is not likely spilling gasses.
If this is in a new house I would report it. If it is in a century home or 50 year old home it was standard at the time.
Downspout extension could hardly be described as life safety, but yes I would report it as basement leaks could be a result and evidence suggests basements are one of the most common complaints or law suits.
Its not a code violation if its existing and predates the current code. It is not a requirement of the code to upgrade unless renovations are planned. There are many existing older structures with S traps that function fine. To suggest they are all code issues or issues that must be remedied is a misnomer, each case maybe different and that is what should be factored in.
Besides the SOP indicate its going beyond the SOP the way I interpret it.
I never indicated that in any way.
Informing my clients of potential issues is my responsibility.
You of course may do as you wish and incur the liability that goes with it.
I do not site code BTW.
I inform my clients of potential concerns, but I don’t make an issue of something that met code at time of construction.
One thing I noticed about people posting questions on this board is they fail to mention age which is a concern in some instances with what is or was permitted and is still permissable. As with this case the postee has not mentioned the age of the structure which will affect the replies.
True, the code was in effect many years before ABS pipe was ever heard of.
Would you call that an “S” trap, it goes into the back wall, not through the floor?
By some of the logic above, I need not be concerned about a improperly installed vent pipe from a gas appliance unless I observe the appliance back-drafting at the time of inspection.
I’m not sure what “logic” you’re referring to, but your conclusion is wrong. An improperly installed gas-appliance vent can be a significant safety hazard even if you don’t observe any back drafting.
That’s exactly my point: we don’t hesitate to call out a improperly installed vent because “it did not appear to be backdrafting at time of inspection”, and we should not hesitate to call out an improperly designed trap because “it did not appear to have lost seal at time of inspection”.
Meanwhile, this morning’s drain plumbing: dishwasher connected to DW tailpiece adapter employed as part of a horizontal run to a center outlet waste tee above the trap inlet. Is there a specific prohibition against using this tailpiece in this manner?
