from Lima, oh
worked great, replaced an older one.
Good product document needs color.
from Scituate, MA
I use this one on my hot water boiler and domestic solar system. Both of my systems use a glycol water mix so it works with a glycol mix. Works great with plain water too. This automatic air relief venting valve is compact and works great. Only problem is the documentation shows the thmub screw ports but not clearly the colors. The red port is for manual relief the black port is for the automatic vent.
