Water heater age decoder
“How old is my water heater?” is one of the most common questions in water-heater service, and the answer decides whether a repair makes sense. Find the plate, record the serial, and get the honest age story with the repair-versus-replace path.
Useful regardless of the serial: the age of a storage tank is the single biggest input to the repair-versus-replace decision, and a leaking tank body is a replacement at any age. Register or check warranty status with the manufacturer where this site links one. Call to check availability.
