A water heater is easy to ignore until it stops working. Regular maintenance can extend its life, improve efficiency, and help you avoid unexpected cold showers or leaks. At Jeffrey’s Appliance Service, we repair both gas and electric water heaters and see many problems that simple upkeep could have prevented.
Basic Maintenance Habits
Flush the tank once a year.
Sediment builds up at the bottom of the tank and reduces efficiency, causes noise, and can shorten the unit’s life. Attach a hose to the drain valve, turn off the power or gas, and flush several gallons until the water runs clear. (If you’re not comfortable doing this, we can handle it during a service call.)
Test the temperature and pressure (T&P) relief valve.
Lift the lever on the T&P valve briefly to make sure water flows out and the valve reseats. This safety device prevents dangerous pressure buildup. If it leaks afterward or won’t reseat, it needs to be replaced.
Check the anode rod.
The anode rod sacrifices itself to protect the tank from corrosion. Most rods should be inspected every 3–5 years and replaced when they’re heavily corroded. This is one of the best ways to extend tank life.
Inspect for leaks and corrosion.
Look around the base of the tank, at the connections, and at the drain valve for any signs of moisture or rust. Small leaks can quickly become big problems.
Set the temperature correctly.
120°F is the recommended setting for most homes. Higher temperatures increase energy use and scald risk; lower temperatures can allow bacteria growth.
Warning Signs
Call for service if you notice:
No hot water or water that runs out quickly
Rumbling or popping noises
Rust-colored water
Leaks around the tank or fittings
The pilot light won’t stay lit (gas models)
The unit is older than 10–12 years and showing problems
