Your water heater is one of the most essential appliances in your home. Whether it's a tank or tankless water heater, regular care and preventive maintenance can save you from sudden breakdowns, cold showers, and high energy bills.
In this guide, we’ll share expert water heater maintenance tips that every homeowner should know to extend your unit’s lifespan and keep your hot water flowing year-round.
🔧 Why Water Heater Maintenance Is Important
Just like your car needs oil changes, your water heater requires periodic upkeep to:
Improve energy efficiency
Reduce the risk of leaks or corrosion
Prolong the lifespan of the unit
Prevent costly repairs or emergency replacements
Ensure safe operation of gas or electric systems
Water heater leaking
🛠️ Top Water Heater Maintenance Tips for Homeowners
1. Flush the Tank Once a Year
Over time, sediment and mineral buildup (especially in hard water areas) settles at the bottom of your tank, reducing heating efficiency and potentially damaging the tank lining.
Steps to flush the tank:
Turn off the power/gas and cold water supply
Attach a hose to the drain valve
Open the valve and let the tank drain completely
Turn water back on to flush out remaining sediment
Close the valve, refill, and restore power
💡 Pro Tip: Schedule this before winter when hot water use increases.
2. Inspect the Anode Rod
The anode rod protects your tank from rusting by attracting corrosion to itself. If it's heavily corroded, your tank is at risk.
Check every 2–3 years and replace it if it’s worn down to less than ½ inch thick.
3. Test the Temperature & Pressure Relief Valve (T&P Valve)
This valve prevents excessive pressure buildup inside the tank. Pull the valve lever periodically (at least once a year) to ensure it releases water freely.
⚠️ If it doesn’t release or keeps leaking after testing, it needs replacement.
4. Set the Right Temperature
Keep your water heater temperature set to 120°F (49°C) to:
Avoid scalding
Improve energy efficiency
Slow down mineral buildup
Reduce stress on the heater
5. Check for Leaks and Corrosion
Every few months, visually inspect the tank (or unit for tankless systems) for:
Rust or corrosion
Water puddles
Moisture around valves or pipes
Early detection can help you catch small issues before they become major repairs.
6. Tankless Water Heater Maintenance Tips
If you have a tankless unit, don’t skip maintenance!
Flush the system with a descaling solution annually (especially in hard water regions)
Clean the filter to remove dust and sediment
Inspect venting, fans, and burners for debris or blockages
7. Insulate the Pipes and Tank
In colder climates, pipe insulation helps prevent heat loss and frozen pipes. You can also add a water heater blanket to older tank models for extra energy savings.
🧰 When to Call a Professional
While many maintenance steps are DIY-friendly, you should call a licensed plumber if you notice:
Discolored or smelly water
Loud popping or banging noises
Low hot water pressure
High energy bills with no change in usage
Water heater over 10 years old without prior maintenance
