Trying to help an elderly neighbor.
All 40 gallon natural gas water heaters. Central Florida. We have hard water, but they have a whole house softener . Water pressure in is 75 PSI. There are no expansion tanks installed in my area, so it's safe to assume there is an open system here. The original builder did install a pressure valve at exterior hose bib, (see pic) not sure if they help or work anyway. Theirs is missing. She did have the water temp set to 160. Not sure about previous settings. TPR was determined to be good
Original water heater failed after 11 years, second one installed in 2011, failed in 2015. Third one failed in 2020. The first failure, not unusual, but mine lasted 18 years, Second one, unknown cause? Her husband took care of these things and he passed away. Third and most recent, State WH , split at the back, (see photo.)
The same company installed the 2011 replacement, so the 2015 was a warranty no cost replacement, but they claim to have no records as to why it was replaced in 2011.
Any ideas about what might be behind this high failure rate. And don't these things explode if the tank is opens while under pressure, seem to remember high velocity explosions used to occur from time to time
