What About My Water Heater?

It’s one of the luxuries of modern life – turn the tap and hot water flows out, ready for baths, showers, laundry and dishes. It’s not something you likely think about often unless your water heater starts giving you trouble.

How Long Does a Hot Water Heater Last?

The life expectancy of a modern water heater is about 10 years, says Brandon Daugherty, owner of High Mountain Plumbing and Heating in Mount Shasta. But Daugherty sometimes sees “dinosaur” water heaters from the 1950s that are still in great condition and working just fine.

It’s important to know the age of your water heater. Yours should have a label that lists its model and serial number, manufacturer, warranty, gallon capacity and other important information. If you know the water heater’s age, you’ll know how closely to watch it for potential problems.

Hot Water Heater Trouble Signs

There are some telltale signs that your water heater is on its last leg. The most obvious is when it’s leaking. This could mean a broken supply line, which a professional can fix, or something more serious. If you have water around your water heater, take immediate action to avoid damage to your home because things could escalate quickly.

Another sign that your water heater is on the fritz: rusty water or water with a strange smell or taste. An old water heater may be rusting away on the inside. Flushing your water heater once or twice a year can prevent buildup of iron, rust and other minerals. To do this, hook up a hose to the valve near the bottom of your tank, open it and allow the dirty water to flow through. This simple maintenance prolongs its life.

Banging or rumbling noises can also point to a problem, though it is normal to hear some sounds from your water heater. “You can hear the element heating the water if you listen closely, but you shouldn’t hear any pops or bangs,” says Daugherty. If your water heater sounds like a rock band is practicing in your garage, don’t panic. It could just mean a pipe isn’t secured.

Hot Water Heater Temps and Tricks

For families with children, Daugherty suggests running water heaters at 120 to 125 degrees Fahrenheit. You can always check the temperature of your hot water with a standard thermometer at a household tap, he says.

Make sure there’s a pan underneath your water heater to prevent any damage to your home in case of a leak. Another important thing is to make sure your tank is secured with earthquake straps. These ensure your tank stays upright in case of an emergency.

If you’re concerned about your water heater, it is a good idea to contact a plumber or other professional who services water heaters.
