Summer vacation is intended to be a relaxing experience—not something you worry about while you’re away. Before you pack up and head out, make sure you’ve taken care of your water heater. A little planning can help you save on energy bills. It can also reduce the risk of leaks and help you avoid unexpected plumbing issues when you return home.
Whether you’re leaving for a weekend or several weeks, taking a few simple steps can help protect your home while you’re away.
Why Check Your Water Heater Before You Leave?
Most homeowners remember to lock their doors, adjust the thermostat, and put their mail on hold before traveling. However, many forget about their water heater.
Even when no one is home, the water heater continues heating water to the temperature you’ve set. This wastes energy and increases utility costs. More importantly, older units can develop problems without warning. A failed component could lead to a serious leak or costly water damage.
Preparing your system before leaving helps reduce these risks and keeps your plumbing system running smoothly.
Lower the Temperature
One of the easiest things you can do before your trip is switch your water heater to Vacation Mode, if your unit has that feature.
Vacation Mode lowers the water temperature while still protecting the tank. It also helps prevent freezing in colder climates. If your unit doesn’t have Vacation Mode, lower the thermostat to 50–60 degrees Fahrenheit while you’re away. This helps reduce standby energy use.
Do not turn the system off completely unless the manufacturer recommends it for your specific model.
Perform a Visual Inspection
Before leaving town, perform a quick inspection of your water heater.
Check for:
- Water leaking beneath the tank
- Corrosion on metal components
- Moisture on supply lines
- Loose or damaged plumbing connections
- Unusual operating noises
- Visible mineral buildup
Finding a small issue before your trip can prevent a much larger rep
air after you return.
If you notice anything unusual, contact a plumber before you leave instead of waiting to see if the problem worsens.
Check the T&P Relief Valve
The temperature and pressure (T&P) relief valve is one of your water heater’s most important safety components. Its purpose is to release excess pressure inside the tank when necessary.
Most homeowners should not test the valve unless they know the proper procedure. However, you should inspect the discharge pipe to make sure it is secure. Also look for signs of leaks, rust, or corrosion around the valve.
If the valve appears damaged or has been leaking, have it inspected before your vacation.
Flush Out Sediment When Needed
Mineral deposits naturally collect at the bottom of the tank over time.
Too much sediment reduces heating efficiency. It also increases energy consumption and forces the water heater to work harder. Homes with hard water often experience faster sediment buildup.
If your unit is due for a routine flush, complete it before leaving. This helps improve performance and extend the unit’s lifespan.
If you’re unsure how to flush the tank, have a qualified plumber perform the service.
Clean the Area Around the Unit
The space around your water heater should always remain clean and free of clutter.
Before leaving:
- Remove boxes or stored items near the unit.
- Keep combustible materials away from gas units.
- Inspect the area for signs of moisture.
- Make sure there is adequate airflow around the equipment.
Keeping the area clear makes leaks easier to spot and helps the equipment operate safely.
Shut Off the Main Water Line (Optional)
If you’ll be away for an extended period, consider shutting off your home’s main water supply.
This simple step can help prevent severe damage if a pipe bursts while you’re away.
Some homeowners also install smart leak detection systems with automatic shut-off valves. These systems monitor water flow continuously. If they detect abnormal water usage, they automatically shut off the water supply.
Using smart technology along with preventative maintenance provides additional protection for your home.
