A couple weeks ago I bought a Taco 007 pump and installed it the other day. The problem is that after I purged the zone properly and powered it up, I did get heat in the zone but the pump is making a bad noise. The boiler pressure is fine, the pump is not mounted upside down or sideways and all the zones work fine. I have a couple other of these same pumps in other zones on this same system and you can barely hear them.
Have you seen many of these pumps being defective out of the box before? Any ideas or suggestions?
