We all have gas, which needs venting. Just not under the kitchen sink.
This is new construction, and a final walk through.
Looking under the kitchen sink I noticed the problem immediately.
Pointing under there I asked everyone present to have a look and tell me what was missing.
The red arrow came later for the report, but shows you what was in question.
As the house has not really been used there was no residual odor.
BUT THERE WILL BE!
This is missing the vent cap, a special cap called an AAV, or Air Admittance Valve.
This valve has special baffles which allows air in to vent the drain properly, but does not allow internal gases out. Those gases typically vent out through the roof, but in this construction connecting to one of those was not possible, so they opted for the AAV instead.
I know the builder was familiar with the AAV because I saw one on the wet bar sink elsewhere, and could show it to my clients.
It's a simple installation.
This is yet another example of how something will be handled later, and totally forgotten.
Well, it will be done now!
My recommendation: again and again, on new construction, things needed to be done that had not been. And there were many things on this house, as there are with many such new construction inspections! When people ask me what kinds of things are "typically" found on these inspections, the answer is nothing is typical. And everything is possible! And yes, the county had approved the plumbing...
* Buyers shouldn't have to know these things. They trust the builder to provide a final product that is properly done and safe. Don't think for a minute that new homes do not need to be inspected privately!
