Changing old vents--what will go horribly wrong?
I'm getting ready to replace the 3 main vents on my early-1900s steam system. This is new territory for me, and a couple of the vents look pretty old, so I want to be prepared for the worst. Do these things ever break when you try to remove them? What do you do if they're stuck so tight you can't get them off with a pipe wrench? What else can go wrong?
The vents that are currently on there are one Dole 6B and two that appear to say "Richardson Bellows".
Many thanks to everyone on this forum. I've learned a huge amount by browsing the archives and reading Dan's books. This is our first winter in our new steam-heated house, and it's become apparent that the system hasn't been well taken care of and needs a lot of work.
