“I see reviews about these should last at least 10 years, this is what I had thought, but I would like to add to that, mine would last 2 years and I couldn't figure out why until I had our boiler replaced! He pointed out that the original installation was backwards all these years, they had the zone valves and circulator pump connected to the output of the boiler with 2 feet of 1" copper between the two, which had the zone valves and circulator pump with 180 degree water always circulating through these components!! Have not had 1 problem with replaceing pump or zone valves since.”
