Bob, I think what Joe and I are saying is that we don’t quote it as code or call it out as a code violation. If its a defect or a concern, code or not, we report on it. We just don’t say it’s a code violation.
I always recommend upgrading non GFCI outlets in older homes. I don’t say they are against code. I say “it doesn’t meet current safety standards” and recommend it as a safety upgrade.
Un-vented S-traps are likely to loose their trap seal due to a siphon allowing unwanted sewer gas to enter the building. Calling this particular trap an S-trap because of the extra short tail piece and the 90 degree turned down trap arm may be right technically BUT it looks like it’s vented inside the wall so it’s not near as bad as if it was going through the floor with no vent.
As opposed to a true S-trap, fixing this one right wouldn’t be a big deal at all.
Good picture,
and why not use ABS?
I am unable to tell what is behind the wall vent or not! Not quite the S trap they used to have in old janitarial mopping school sinks. So if it is vented in the wall, it is not an S trap.
Wouldn’t you know. I found every bath trap in this newly renovated building like this one in the photo. And what do you think of this shower drain? I’m thinking the “plumber” had no idea what a proper trap is.
