How to Maintain Your Electric Water Heater

Hot water isn’t a luxury. It’s part of daily life. Showers, dishes, and laundry all depend on a water heater that works the way it should. Most people don’t think about theirs until it starts acting up. In places like Cincinnati and Dayton, where hard water is common, maintenance isn’t optional. It’s what keeps your system efficient and safe through cold Ohio months.
You can handle a few easy checks yourself. For the rest, Apollo Home’s licensed plumbers can step in and keep things running right.
Why Water Heater Maintenance Matters
A water heater that’s maintained regularly runs smoother and lasts longer. When sediment builds in the tank, it forces the elements to work harder and use more electricity. That means higher bills and slower heating.
Regular upkeep helps:
- Lower your energy use
- Prevent mineral buildup inside the tank
- Extend the system’s lifespan
- Catch small leaks before they turn into water damage
Hard water in Southwest Ohio makes maintenance even more important. The minerals that settle in your tank will wear it down faster if they’re not flushed out.
Safety First: Turn Off Power and Water
Before you touch anything, make sure the power and water are off. Electric water heaters run on high voltage, and the water inside can be scalding.
Always:
- Flip the breaker switch to cut power to the unit
- Turn off the cold-water valve feeding the tank
- Let the tank cool for a while before you start
Safety comes first. Once everything’s shut down, you can move ahead without risk.
Step-by-Step Maintenance
You don’t need to be a plumber to do basic upkeep, but it helps to know what each step does. Here’s how to maintain your electric water heater.
1. Flush the Tank: Sediment collects at the bottom of the tank, especially with hard water. If you hear popping or rumbling, it’s likely buildup.
To flush:
- Hook a garden hose to the drain valve
- Run the other end outside or into a drain
- Open the valve and let it empty until the water runs clear
- Close the valve and refill the tank before turning the power back on
This clears out debris that forces the elements to overheat.
2. Check the Heating Elements: The heating elements inside the tank handle all the work. If they corrode, you’ll notice longer recovery times or cooler water. A licensed tech can test and replace these safely.
3. Test the Pressure Relief Valve: That small valve near the top of the tank keeps pressure under control. Lift the lever slightly to see if water releases. If it doesn’t, or it leaks afterward, it’s time for a new one.
4. Inspect the Anode Rod: This rod attracts minerals, so your tank doesn’t rust. If it’s eaten away or coated in calcium, it needs replacing. It’s a simple fix that can double your tank’s lifespan.
5. Insulate the Tank and Pipes: Wrapping your tank and hot-water lines helps retain heat, especially in cold basements. You’ll waste less energy and get hot water faster in winter.
6. Look for Leaks or Rust: Check the base, valves, and fittings for signs of moisture or corrosion. Even a slow drip is a problem. Catching it early keeps it from turning into a bigger leak later.
Signs You Need Professional Help
Some issues call for a licensed plumber. Don’t try to fix these on your own:
- Loud banging or popping noises from the tank
- Cloudy, rusty, or foul-smelling hot water
- Not enough hot water or temperature swings
- Water pooling around the base
These are signs of worn elements, sediment buildup, or pressure problems. Apollo Home’s plumbers can inspect the system and handle repairs safely.
How Often to Service an Electric Water Heater
Most homes should service the unit once a year. If you live in an area with hard water, twice a year is better. It keeps minerals under control and helps you avoid cold showers when you need hot water most. Many Cincinnati and Dayton homeowners use Apollo Home’s Care Plan.
