I have a 1 pipe steam system. There was no main air vent installed, I think it was plugged. Last year, I have a plumber installed a Gorton 1 main air vent where it was plugged:

If you look at this pic:

This is the end of the main pipe and then curve to the left to a raditor and then pic 1. There are 3 risers that feed 2 raditors in the first floor and 4 in the second floor.

My question is, by having the main air vent there at the return, does it serve any purpose? I haven't really noticed. Also, will adding another Gorton 1 with a tee there will help? I have a water hammer problem in my master bedroom. Air vent is changed, radiator is pitched. Also, my bathroom vent and third bedroom hisses loudly. I did some skimming of the boiler but probably still need a more thorough skimming. It's much better than when I bought the house last year thought.

Oh, and here is a pic of the boiler. It's a Weil McLain EG45 (the pressure relief valve is piped down but not shown in pic)
