Hello. Just bought a new house and working on getting the heating system working properly.
Boiler: Weil-McLain CG-5 Series 12
My main question is:
While looking in the owners manual for my boiler I noticed that the current expansion tank was "not installed properly" and my hunch is that it was improperly modified from the original installation.
The manual's instructions:
There has been some scares with the system over the weekend where the pressure was reading "55 PSI" one time and "70+ PSI" and other time. Once I saw the 55 PSI I called a professional. I'm working with a HVAC company who came out today but it seems like the tech wasn't too knowledgeable on my specific system.
I tinkered with it yesterday (before the pros saw it today) and came to the assumed conclusion that it is the expansion tank that is the issue and possibly the TP gauge as well. The relief valve is definitely bad as it has a slow leak. Today the pros concluded the same thing. The reducing inlet valve was ruled as a suspect contributor to the problem.
The original boiler was properly sized for the house at the time of installation. Since then, there has been two additions to the house and radiators added to the attic/finished 3rd floor.
