How to Extend Your Water Heater’s Life

If your hot water starts feeling lukewarm or you’re paying more on the energy bill, the first thing to check is your water heater’s health. A few quick habits can add years to the tank and stop surprise breakdowns. Below are the top things you can do yourself, plus when to call a pro.

Regular Flushing and Sediment Removal

Every 6‑12 months, drain a few gallons of water from the tank. Sediment from minerals builds up at the bottom, making the heater work harder and shortening its life. To flush:

• Turn off the power (or gas) and let the water cool for an hour.
• Connect a garden hose to the drain valve at the bottom of the tank.
• Open the valve and let the water run until it looks clear.
• Close the valve, refill the tank, and turn the power back on.

It takes less than 15 minutes and can improve efficiency by up to 20 %.

Check the Anode Rod and Other Key Parts

The anode rod is a metal stick that sacrifices itself to stop the tank from rusting. If it’s worn down, the whole tank can corrode. Pull the rod out with a wrench and look for at least ½ inch of exposed metal. If it’s mostly smooth or less than that, replace it.

While you’re at it, glance at the temperature setting. 120 °F (49 °C) is hot enough for a comfortable shower and helps prevent mineral buildup. Also, inspect the pressure‑relief valve by lifting the test lever; you should hear a quick rush of water and then it should close snugly.

If any of these parts look damaged, schedule a service visit. A professional can replace the rod, tighten connections, and make sure the venting is safe.

Other quick habits:

• Leave the cabinet door open for a few minutes after each use. This lets heat escape and reduces stress on the tank.
• Install a water softener if you have hard water. Softer water means less scale inside the heater.
• Turn the thermostat down a degree in winter months; you’ll still have hot showers, but the tank won’t overwork.

Watch for warning signs like rumbling noises, rusty water, or a sudden drop in hot‑water supply. Those clues mean it’s time for a professional check before a total failure.

By flushing, checking the anode rod, and keeping the temperature and pressure valves in check, you can add several years to your water heater. Less money on repairs, more reliable hot water, and a lower energy bill – all with a few easy steps.
