As summer winds down in Marshall and the cooler fall months approach, now is the perfect time to give your water heater the attention it deserves. Many homeowners don’t think about their water heater until something goes wrong—but a simple end‑of‑summer maintenance routine can extend its lifespan, improve efficiency, and prevent unexpected breakdowns just as temperatures begin to drop.

At Bisbee Plumbing & Heating, we see a spike in water heater service calls every fall. Sediment buildup, worn components, and lack of maintenance are usually to blame. Taking care of your system in August not only prepares it for heavier winter usage—it also helps you avoid costly mid‑winter replacements.

Why Late Summer Is the Best Time for Water Heater Maintenance

August is the ideal time for water heater flushing and tune-ups for a few key reasons:

• Water heaters work harder in fall and winter —you’ll want maximum efficiency before colder temperatures hit.
• Sediment builds up faster in warm-weather months due to increased hot water usage.
• Fall is a smart time for replacements —if your heater is aging, you can upgrade before winter demand peaks.
• Homeowners are already preparing for seasonal changes, making preventive maintenance feel timely and worthwhile.

Why Flushing Your Water Heater Matters

Over time, sediment from Minnesota’s water supply settles at the bottom of your tank. This buildup can cause:

• Lukewarm or inconsistent hot water
• Loud popping or rumbling noises
• Reduced efficiency and higher utility bills
• Premature tank wear and corrosion
• Longer recovery times after showers or laundry

Flushing your system removes this sediment and helps your unit operate smoothly heading into the cold months.

How to Flush Your Water Heater (Step-by-Step)

Note: If you’re not comfortable performing these steps, the Bisbee team is always here to help.

1. Turn Off Power or Gas Supply

For electric heaters, switch off the breaker. For gas models, set the thermostat to “pilot.”

2. Shut Off the Cold Water Supply

Locate the cold water valve at the top of the tank and turn it off.

3. Connect a Garden Hose

Attach the hose to the drain valve at the bottom of the tank and run it to a floor drain or safe outdoor area.

4. Open the Drain Valve

Allow the tank to empty completely. The water may come out cloudy or sandy—that’s the sediment leaving the tank.

5. Flush With Fresh Water

Turn the cold water supply back on briefly to stir up any remaining sediment, then drain again.

6. Close the Valve and Refill

Once the water runs clear, close the drain valve, turn on the water supply, and allow the tank to refill fully.

7. Restore Power or Gas

Turn the breaker back on or relight/activate the gas burner.

Additional Water Heater Maintenance Tips

• Check the anode rod —this component prevents corrosion but wears down over time.
• Test the temperature & pressure (T&P) relief valve to ensure safety.
• Set the thermostat to 120°F for efficiency and safety.
• Inspect for leaks around fittings, valves, and the base of the tank.

When Should You Consider Replacing Your Water Heater?

If your system is over 10 years old, struggles to keep up, makes loud noises, or shows signs of rust, fall is an excellent time to upgrade. New energy-efficient models provide better performance, lower utility bills, and more reliable hot water during Minnesota’s long winter months.
