Question: How old is my water heater?
Answer: To see how old your water heater is, locate the sticker or plate on the water heater that shows a set of codes. Then Google the brand and decoder guide. The codes (numbers and/or letters) will show the month and year the water heater was manufactured. In some cases, the manufacturing date is displayed in plain text.
