I'm not sure of the proper terminology for the piping here. To me, it looks like a plumbing trap, so thats what I'll call it here until someone corrects me.
The pipe on the bottom left is a steam main from the boiler, top left is a dry return back to the boiler, pipe on the right is the other steam main from the boiler.
My question is regarding this "trap" in the middle of the mains. It has a plug in the bottom of it for draining. Should I keep this "trap" empty, of should it hold water for a reason? If it's meant to be dry I will put a valve on it and pipe it to a drain. It it's meant to stay wet I'll just leave it alone.
