Want Your Casselberry Water Heater to Last? What Annual Water Heater Maintenance Includes

by Sheila Beasley · 5 min read

Plumber checks a drain hose connected to an electric water heater during annual tank maintenance.

Annual water heater maintenance covers four things: flushing sediment out of the tank, checking the anode rod, testing the temperature and pressure relief valve, and inspecting the connections for early leaks. Done once a year, it's the simplest way to stretch the life of the heater you already have.

It also catches small problems before they flood a closet or leave you with a cold shower. To set up a visit, contact our team or call (407) 273-6260.

Why does flushing sediment matter so much in Central Florida?

Because our water is hard. Central Florida's groundwater comes from limestone, and it carries a lot of calcium and magnesium. When that water heats up, the minerals settle to the bottom of the tank as sediment, and every year the layer gets thicker.

That layer sits between the burner or lower element and the water. The heater has to work harder and run longer to get the same hot water. Over time, the bottom of the tank overheats, the metal weakens, and you lose usable capacity, so the hot water runs out sooner.

A customer called us after his water heater started making strange noises that he noticed over his morning pastry. He feared the worst, figured he needed a whole new unit, and started comparing prices. He was glad he called first. We found sediment buildup, fixed it, and recommended a maintenance plan. He was happy to set one up for the peace of mind.

Those popping and rumbling sounds are common in homes around Lake Concord, where many tanks haven't been flushed in years. During a flush, we drain the tank through the bottom valve until the water runs clear.

What does checking the anode rod actually do?

The anode rod protects the tank from rusting from the inside. It's a metal rod that corrodes on purpose, so the steel tank doesn't. Once the rod is used up, the tank itself starts to corrode, and a leak usually isn't far behind.

Hard water wears anode rods out faster. During a maintenance visit, we pull the rod and check how much is left. If it's down to the core wire or heavily coated, we replace it. A new rod costs far less than a new tank.

Your water can give you clues, too. Rusty hot water or a rotten-egg smell from the hot side only can point to a worn or reacting anode. Many ranch homes built in the 1960s and 1970s off Red Bug Lake Road still have older tanks where nobody has looked at the rod in years.

Not every tank has an easy-to-reach anode, and some are seized in place. That's one reason this step is best left to a plumber with the right tools. Our water heaters page covers the repair and replacement work we handle.

Why test the temperature and pressure relief valve?

The T&P valve is your water heater's safety release. If temperature or pressure inside the tank climbs too high, the valve opens and lets water out. If it's stuck shut, there's nothing to relieve that pressure.

We test the valve by lifting the lever and making sure it opens, releases water, and seals again. Mineral buildup from hard water can freeze a valve in place, or keep it from sealing so it drips constantly. Either way, we replace it.

We also check the discharge pipe that runs from the valve. It should be the right size, run in the right direction, and end where water won't cause damage. It's a small detail that matters a lot in a garage or closet install near Secret Lake.

While we're there, we check the thermostat setting. Most households do well around 120 degrees. Running hotter adds stress to the tank and speeds up mineral buildup, and it raises the risk of scalding, especially with kids in the house.

What else does a maintenance visit inspect?

We check every connection for early signs of trouble: the water supply lines, the shutoff valve, the drain valve, and, on gas units, the gas line and venting. Small drips, green or white crust on fittings, or rust around the base all tell us where a leak is starting.

Skipping maintenance doesn't usually cause a dramatic failure right away. It shortens the tank's life quietly, year by year, until the bottom rusts through. Annual care helps you get every year you can out of the heater, and gives you time to plan a replacement instead of scrambling for one.
