Key takeaways
- A leaking tank is always replaced, not repaired.
- Heaters past about twelve years often deserve replacement.
- If a repair costs close to half a new heater, replace.
- Planned replacement avoids an emergency flood.
Signs it is time
Water pooling around the base, rusty hot water, a heater over ten to twelve years old, banging noises from sediment and repeated repairs are the usual signals. A leak from the tank body cannot be fixed.
A heater that has stopped heating may only need a thermostat or element, and those repairs are usually worthwhile on a younger unit.
The money question
Compare the repair cost with a share of a new heater. If a repair is more than about half the price of replacement, or if the heater is past its expected life, replacement usually makes more sense. A new unit also brings better efficiency and a new warranty.

Plan it instead of reacting
Replacing a water heater on your schedule means you choose the model, avoid an emergency premium and skip a flooded garage. If yours is old, ask a plumber to look at it, check the anode rod and tell you what to expect.

Quick answers
How can I tell how old my water heater is?
Look at the serial number on the label. Many manufacturers encode the year in the first digits, and the label often includes a date.
Is it worth flushing an old heater?
Flushing helps younger heaters, but on an old tank with heavy sediment it can sometimes start a leak. A plumber can advise.
