    Air Purge

    There are no valves to isolate a wing of our building. I want to put ball valves on the supply and return with boiler cocks on the wing side to get rid of the air. Does it matter if I open the supply and keep the return closed or if I open the return and keep the supply closed?

    Frank, Thanks. I thought I should do it that way. My buddy said it didn't matter. Now I have a reason.
