Question Washing Machine Vent Pipe

Someone please help me.

I have had a plumber working on a bathroom renovation for me and I am questioning some of the work. One question is about the washing machine vent pipe. He initially said that he was going to run it up into the attic and connect it to the existing vent pipe that goes through the roof. Once he left, I checked it and he hadn't connected it at all. It runs right up to the existing vent pipe and ends with a black cap....He installed (from what I can tell) a "check vent"??? Does this sound like a good idea? The vent pipe is about 20' long with several turns before it ends with that black "check vent". Does the placement matter?

Depending on where the bends are and how they are made they may okay. The "check vent" may be a Studor vent, also known as an air admittance valve. It is sometimes allowable in certain instances but is inferior to having the vent connect to the piping through the roof.
