In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Any ideas as to why someone would pipe to check valves into the top of a steam boiler like this? When I asked a guy at this site he replied that it was a vacuum breaker. Doesn't seem right or necessary to me. Any thoughts? The ball valve stays open throughout operation and they said steam doesn't come out. I was actually there to check something else but noticed this. When I asked why it was there they replied because they boiler works so we don't touch it. Thanks, Mike.
