Your water heater works hard every day to deliver hot water to your sinks, showers, and appliances. But without regular water heater maintenance, it can wear down faster, lose efficiency, and even fail unexpectedly. At EVERYDAYPLUMBER.com, we help Tampa Bay homeowners keep their water heaters running smoothly and lasting as long as possible.
In this guide, we’ll show you how to maintain your water heater step by step, and share professional tips to help you avoid cold showers and costly repairs.
Why Water Heater Maintenance Matters
Most water heaters last 8–12 years, but with routine water heater maintenance, you can often extend that lifespan to 15 years or more. Saving you the cost and hassle of premature replacement.
Here’s what you gain by keeping up with it:
- Better energy efficiency (lower utility bills)
- More consistent hot water
- Reduced risk of leaks or tank failure
- Longer lifespan for electric or gas models
Just like changing the oil in your car, regular upkeep ensures your water heater performs at its best for years to come.
1. Flush the Tank Annually
Sediment buildup from Tampa Bay’s hard water is one of the most common causes of early water heater failure. Minerals like calcium and magnesium settle at the bottom of the tank and insulate the heating element, forcing it to work harder.
- How to flush your water heater:
- Turn off the heater (electric breaker or gas valve)
- Shut off the cold water supply
- Attach a garden hose to the drain valve and run it outside
- Open the drain valve and empty the tank
- Turn cold water back on briefly to stir and flush sediment
- Close valve, refill the tank, and restore power

2. Check the Anode Rod
The anode rod is a crucial component that protects your water heater tank from corrosion. It’s designed to attract and neutralize corrosive minerals in the water, sacrificing itself instead of your tank. Over time, this rod will degrade, and if it’s fully depleted, your tank becomes vulnerable to corrosion..
When to check it: Every 2–3 years
Replace it if: It’s less than ½ inch thick, heavily pitted, or coated with calcium buildup
This small part can add several years to the life of your water heater when replaced on time.
Want Even Better Protection? Consider a Corro-Protec Powered Anode Rod
A powered anode rod uses a small amount of electrical current to create a stronger, more consistent protective field inside your tank. It offers several benefits over traditional sacrificial rods:
- Permanent corrosion protection
- Reduces sulfur smell in hot water (no more rotten egg odor)
- Prevents mineral buildup and sediment
- Works in all water conditions, including hard water
Upgrading to a powered anode is an excellent option if you’re looking to maximize the lifespan of your tank-style water heater. Especially in areas like Tampa with mineral-rich water.

3. Lower the Temperature Setting
Most water heaters are set to 140°F by default. Lowering the thermostat to 120°F can:
- Save energy (up to 10%)
- Reduce scalding risk
- Slow mineral buildup
Simply locate the thermostat on your tank and adjust the dial.
4. Inspect for Leaks or Rust
Take a look around the base of your tank monthly. Watch for:
- Pooled water or active drips
- Rusty streaks
- Moisture near the temperature & pressure relief valve (T&P valve)
Catching these early signs can prevent water damage and alert you to hidden problems.
5. Test the T&P Relief Valve
The temperature and pressure relief valve is a critical safety feature that releases pressure if your tank overheats. To test it:
- Place a bucket under the discharge pipe
- Pull the T&P valve lever briefly
- You should hear a rush of water, then it should stop
If it doesn’t drain or keeps leaking afterward, the valve may need replacing.
Bonus Tip: Schedule a Professional Inspection
Even with DIY care, it’s smart to have a plumber inspect your water heater once a year. We’ll check all components, flush the tank, and catch any issues before they become costly repairs.
