Purging Home Boiler
2 Attachment(s)
Hi, I have a 1960's American Standard boiler that has two zones, one of which is not heating. Can also hear water running so believe problem is that system needs to be purged? Read alot of info but none of set-ups seem to be same as mine so looking for advice before I attempt. Going to attach two pictures. One showing return and water supply, second the outlet and expansion tank setup. Just prior to hose bib and gate valve on return there is a TEE for two zones, each of these also have a small gate valve.

I apologize for going off topic, but there's definitely someone on this board better suited than me to answer your original question..

What does that PVC pipe do? It makes me nervous to see that dip..

PVC pipe
PVC pipe is for central vac system not heating

Cool, sorry to bother you.. knew it wasn't heating, but worried it might be DWV.
