Your water heater works every day to keep your showers hot, your dishes clean, and your laundry running smoothly. But without regular water heater maintenance, it can lose efficiency, develop costly problems, or even break down when you need it most.
At EVERYDAYPLUMBER.com, we help Tampa Bay homeowners protect their investment with simple maintenance tips and expert service that keeps water heaters running longer.
In this guide, you’ll learn the key steps for water heater maintenance, how to spot signs of trouble early, and which tasks are best left to the pros—so you can avoid cold showers and unexpected 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 early replacement. Keeping up with maintenance isn’t just smart, it’s one of the best ways to get more out of your investment in home comfort.
Here’s what you gain by keeping up with it:
- Better energy efficiency (lower utility bills) – A well-maintained unit uses less power. Need help reducing high bills? Contact us for a water heater tune-up.
- More consistent hot water – Maintenance prevents sudden cold showers and makes everyday routines easier.
- Reduced risk of leaks or tank failure – Regular inspections and repairs can catch issues early. Learn about our emergency plumbing services if you spot warning signs.
- Longer lifespan for electric or gas models – Whether you have an electric or gas water heater, proper care means fewer replacements.
Just like changing the oil in your car, a little regular plumbing maintenance goes a long way. Routine water heater upkeep helps Tampa homeowners avoid surprises, save money, and keep hot water flowing year after year.
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
Not comfortable doing this yourself? Our Tampa plumbers can handle it quickly and safely.
2. Check the Anode Rod
The anode rod protects your water heater tank from corrosion. It attracts and neutralizes corrosive minerals, sacrificing itself instead of your tank. When the rod is depleted, your tank becomes vulnerable to rust.
-
When to check: Every 2–3 years
-
Replace it if: Less than ½ inch thick, heavily pitted, or coated with calcium
Plumbing Tip: Replacing this small part can add several years to your water heater’s lifespan.
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.
Ask us about installing one during your next water heater service or inspection.
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
How to adjust: Locate the thermostat dial on your tank and set it to 120°F.
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 avoid expensive repairs.
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 Plumber Tip: Schedule a Professional Inspection
Even with good DIY habits, an annual professional inspection is the best way to catch hidden issues early.

Frequently Asked Questions About Water Heater Maintenance
Q: How often should I flush my water heater?
At least once a year—or every 6 months if you have hard water in Tampa. Regular flushing helps prevent sediment buildup and keeps your hot water flowing strong.
Q: What type of water heater lasts the longest?
Tankless water heaters can last 15–20 years with proper maintenance. Standard tank models usually last 8–12 years.
Q: Should I turn off my water heater when I go on vacation?
If you’ll be away for more than a week, yes. Setting it to vacation mode or turning it off at the breaker (electric) or gas valve saves energy and reduces risk of leaks while you’re gone.
Q: How do I know if the anode rod is bad?
If the rod is corroded down to the steel core or coated in minerals, it’s time to replace it—this helps prevent tank rust and failure.
