Buying & Hiring · 4 min read · By the OutToday team

Tank water heaters don't last forever. Most last somewhere around 10 to 15 years, and when they fail, they often fail suddenly, sometimes with a leak that damages floors and walls. Replacing on your own schedule almost always beats replacing in an emergency.

Signs your water heater is nearing the end

  • Age: check the date on the manufacturer's label. If it's past 10 years, start planning.
  • Rust-colored hot water, or rust around the tank or connections
  • Rumbling, popping, or banging noises, often from sediment built up at the bottom of the tank
  • Water pooling around the base of the tank
  • Less hot water than you used to have, or water that never gets as hot as it should
  • Frequent repairs

Repair or replace?

A bad thermostat, heating element, or valve on a younger tank is usually worth repairing. A leaking tank cannot be repaired, because the leak is coming from the tank itself. And if the unit is old and needs a significant repair, the money usually goes further toward a replacement.

What to do before it fails

  • Know where your water shutoff valve is, and where the gas or power shutoff for the heater is.
  • Consider a drain pan and, where appropriate, a leak sensor.
  • Have the tank flushed periodically to reduce sediment.
  • Decide ahead of time whether you're replacing like for like or considering a tankless upgrade.

If you see water on the floor

Turn off the water supply to the heater and shut off the power or gas, then call a plumber. Don't wait to see whether it stops on its own.

Replacing on your schedule

Planning gives you time to compare options, get written quotes, and choose the right size and type. Emergency replacement leaves you with whatever is available today. If your water heater is past 10 years, it's worth an inspection now.
