Hey all, first time poster here and relative newbie when it comes to boilers. I've replaced a zone valve head on my own before so not completely in the dark.
My issue is with a taco circulator Pump that is making noise. Seems to only make the noise when the upstairs zone (zone 2) is not calling for heat but one or both of the other 2 zones (zone 1 and 3) are. See the linked video for an example of the sound and how it goes away when zone 2 opens up.
