Flush the Tank Annually
Flushing your tank removes sediment that settles at the bottom over time. Sediment buildup forces your heater to work harder, using more energy and potentially causing overheating. Regular flushing keeps your system efficient, lowers utility bills, and reduces strain on the unit.
Replace the Anode Rod
The anode rod attracts corrosion, protecting the tank’s lining from rust. Replacing it on schedule prevents leaks, preserves tank integrity, and extends the life of your water heater. A small investment now can save thousands in replacement costs later.
Check the Thermostat Setting
Keeping your thermostat around 120°F ensures safe, comfortable hot water while reducing energy waste. Correct settings prevent overheating, minimize pressure inside the tank, and lower scalding risks, protecting both your family and your system.
Test the Pressure Relief Valve
The pressure relief valve releases excess pressure when the tank overheats or builds up stress. Test it by lifting the lever to ensure water flows and reseals correctly. Regular testing prevents dangerous tank bursts, protects surrounding plumbing, and ensures safe operation.
Insulate the Tank
Adding insulation to your water heater and pipes reduces heat loss, shortens heating time, and lowers monthly energy bills. It also reduces strain on your system, especially during colder months, and keeps hot water readily available when you need it.
Look for Leak Spots Around Fittings
Check valves, joints, and connections for moisture. Early detection of leaks prevents damage to floors, walls, and nearby appliances, reduces mold risk, and protects your home’s plumbing system from further issues.

Sediment forms when minerals like calcium and magnesium settle at the tank bottom. Over time, it hardens, blocks heat transfer, and strains internal components. Regular flushing and cleaning prevent damage, protect plumbing, and extend your heater’s lifespan.
Problems caused by sediment buildup include:
- Reduces Heating Efficiency
A thick layer of sediment blocks heat from reaching the water evenly, forcing the heater to use more energy. This leads to higher utility bills and slower heating, especially in areas with hard water.
- Causes Overheating
When sediment traps heat at the bottom of the tank, the burner or heating element runs longer than needed. This extra strain cracks the tank lining and damages internal parts over time.
- Increases Corrosion Risk
Sediment creates pockets where moisture and minerals speed up rust formation. Corrosion weakens the tank walls and fittings, raising the chance of leaks or early system failure.
- Leads to Inconsistent Water Temperature
Sediment blocks the heater from heating water evenly. Older systems may cause homeowners to notice sudden changes in water temperature during showers or tank refills.
- Raises Maintenance
As the buildup increases, the heater needs more flushing, repairs, and part replacements. Ignoring it shortens the system’s lifespan and leads to expensive replacements, which can be avoided with routine care.
