Inspected a home the other day that had been “remodeled”. The home was only 20 years old, but the kitchen cabinets and sink had been moved to the other side of the room. I couldn’t see how the sink drain was vented, and it gurgled when I ran a large amount of water, so I called it out. The buyer asked the owner to fix i - I recommended an AAV be installed. The plumber wrote on letterhead that the sink was installed “according to code.” But then in conversation with the buyer, admitted that it was NOT vented… WTH?
That little 1.5” P-trap gurgled when it was dumping into a 3” drain. I don’t believe it. What makes you think you need an AAV?

That’s the first thing that jumped out at me…3” drain.

It’s called a combination waste and vent system. It’s a very legal installation and done well.

Yes, a lot of air in the pipe with the draining water.

This is called a combination, waste and vent system. I don’t believe the drain gurgled. I think some home inspectors see something they’re not familiar with and imagine this must be a defect. It must be gurgling.
A licensed plumber backed up his knowledge on his company letterhead. The home inspector still thinks it’s wrong.

Well, you can believe what you want, but the sink was filled with water, then drained. It stopped draining after a short time, a big bubble came up, then a few more, then it slowly drained, making noise as it did. I did note the 3" drain, which is different from anything else in the home.
That would have been my narrative. Then my recommendation for a plumber.
Determining causation is the fastest route to confrontation. Pick and choose these battles carefully. I typically avoid it, especially if it involves a specific skilled trade.
Here is the NACHI SoP. I am not sure what FL SoP says in this situation.

So which is it?
Brian, thank you - in my narrative, I did just that, but I also noted the drips of waste on the pipe, and the need for evaluation of the installation.

It looks like it’s leaking where the 3" elbow is not plumb/crooked ABOVE the drain fitting.
Was the “plumber” licensed or was it someone working under the licensed plumber? “According to Code” did he specify the Code? I only ask this because in my area (not too far from you) “it passed Code” (or it “pasted” Code as one “licensed” trade once proclaimed in writing) is the favorite go to excuse for many of the trades. Can’t see in the pics but was there stains under the plumbing on the cabinet? Gurgling in plumbing is an indication of improper drainage regardless of installation configuration.

Wanna bet it was the same plumber that originally installed it for the remodel?!!

Or, could have simply been a creative Seller with a computer, Google Search, and some basic software!!

No - plumber is licensed and active. Buyer says he spoke with him. I’d bet he was the installer though - inspection was done on 3/10, buyer got around to reading the report on 3/11, and his (plumber’s) response on letterhead was written on Saturday 3/15. Buyer is a snowbird, and this property will be vacant half the year… he doesn’t want a problem.
