Annual Water Heater Flush Reminder and Tracker

Protect your investment. Keep your hot water flowing.

Your water heater works hard every single day—whether it’s a traditional tank system or a tankless water heater. But here’s the catch: Jacksonville’s hard water creates sediment that builds up over time. If left unchecked, this debris can:

Shorten the life of your water heater
Reduce efficiency and increase energy costs
Lead to discolored or smelly water

That’s why flushing your water heater annually is one of the best things you can do to maintain reliable, affordable hot water for your home.

Why Flushing Your Water Heater Matters

Extend Lifespan
Prevents corrosion, overheating, and early tank failure.
Improve Energy Efficiency
Sediment buildup forces your heater to work harder—costing you more on your energy bill.
Better Water Quality
Enjoy cleaner, clearer water for showers, laundry, and cooking.
Peace of Mind
Stay ahead of problems before they lead to costly repairs or replacement.

Step-by-Step: How to Flush a Water Heater

Whether you have an electric, gas, or tankless water heater, these steps work for most systems:

Turn off the power supply
For electric units, shut off the breaker. For gas, set the heater to “pilot.”
Close the cold water inlet valve
This stops new water from entering while you flush the tank.
Attach a garden hose
Connect it to the drain valve at the bottom of the tank and run it to a safe outdoor drain or bucket.
Open the valve and drain completely
Allow all the water (and sediment) to flow out.
Close the drain valve and remove the hose
Then reopen the cold water valve.
Restore power or relight pilot light
Once the tank is full again, turn the system back on.

When to Flush More Often

Jacksonville has hard water, so homeowners may need to flush their heaters every 6–12 months, especially if:

You hear popping or rumbling noises from your tank
Hot water smells metallic or looks rusty
You have an older water heater
You don’t have a filtration or softening system

Have a filtration system? That should be serviced once a year too.
