I found two of these in the crawlspace of home heated by three 50 gallon water heaters. I did not find any kind of thermal expansion device anywhere, including in the toilet tanks.
I think there where expansion tanks hanging from the bottom of the 'T' at one time? Don't know why they have been removed.
What is the device at the top of the 'T'?
