Here I go through the diagnosis process for a stuck boiler circulator pump and then the step by step instruction for how to replace the failed pump while draining as little water as possible from the system.

If your boiler / water furnace is not working this is a very common issue as hydronic circulator pumps are a wear part that will fail after 10 or 20 years of use.
