I live in Nashville. Been in this house for 14 year & 3 gas water
heaters. Replaced the original a few years after we moved in. Home
Depot, don't remember the brand. 5 year warranty. Kept the receipt in
warranty folder. 4 years, 2 mos. later it fails.
HD replaces it w/GE 40 gal. Replaced it once after 3 years & am
getting ready to do so again.

Do you have a dielectric coupling in the system?


Copper back to water meter. The only thing between meter & heater are
the 2 whole house filters I mentioned. The housings are PVC. One "paper"
sediment filter & one carbon activated filter for chlorine.
