P/N AM101-US-1 AM-1 Series. Thermostatic Mixing Valve for furnace. Installed Aug. 2, 2006. Was Weeping for a long time but recently has been leaking above what looks like a nut built into the valve. Soldered connections appear ok. Searched for part on company web site. No Match. Guess Honeywell decided to scrap the part: maybe too many problems. So what do I do now to replace, or eliminate the bad valve on my furnace? Furnace is a Crown boiler which also supplies our hot water.
