elgato Posted September 5, 2014 Report Share Posted September 5, 2014 Saw this mounted on top of a State Industries electric water heater manufactured in 1983. No TPR valve, as I know them anyway. Anyone able to enlighten me on this? Thanks Click to Enlarge 58.17 KB Quote Link to comment Share on other sites More sharing options...
elgato Posted September 5, 2014 Author Report Share Posted September 5, 2014 My guess is that this "fuse" melts at a high temp and opens to release excess pressure/heat, like today's TPR valve. Quote Link to comment Share on other sites More sharing options...
kurt Posted September 5, 2014 Report Share Posted September 5, 2014 A fusible plug has the same general function as a fusible link; it melts at a predetermined temperature. Never seen nor heard of such a thing on a water heater. Easy fix though....get a new water heater, it's 30 years old, it's time. Quote Link to comment Share on other sites More sharing options...
John Kogel Posted September 6, 2014 Report Share Posted September 6, 2014 Yikes, that thing doesn't blow until the water hits 195 degrees, that's cutting it pretty fine for a residential water heater, no? It is haywire. Look at the elbow and the missing discharge tube. Mr Handy strikes again with a haywire safety device. Quote Link to comment Share on other sites More sharing options...
Marc Posted September 6, 2014 Report Share Posted September 6, 2014 Looks too distant from the tank to correctly sense the hot water temperature. Further reason to replace the entire appliance. Marc Quote Link to comment Share on other sites More sharing options...
