Would you mind measuring the diameter of the t-piece where it plugs into the lung? TIA
50.25 mm. Here's a pic to see the diverter as well.

Fathom question, does the exhale counterlung tpiece/adv have a baffle for water diversion into the lung?
Yes. At least on my version which has the adv but it is my understanding that it is present on the non-adv versions as well. Flood tolerance was one of the many things well thought out when Charlie built the fathom so I can’t imagine he didn’t leave the baffle when he chose to stop selling it with the adv as standard.

Edit: whops somehow I missed that inquis answered already

Correctamundo, no ADV on my unit.
 
I think they don't even carry the ADV any longer...at least I could not order one recently. @inquis do you have a bov or do you just rely on the mav for dil make up?
 
I have a BOV. I have played with detuning+barely cracking it open on hot drops (effectively acting as an ADV), but I normally keep up without issue using the MAV alone.
 
The adv is on the exhale side isn't it? There's no baffle in my adv unless it's just been that long since I looked at it. Entirely a possibility.

The pic @211ratsbud posted shows IQSub T-pieces, which is a change from what mine has. It might be worth an email to Charlie if you're going to buy something new (or he might still have some non-IQSub around).
