Black Ops
See inside it before anyone quotes you
Seven parts, what each one does, and which ones we replace. Scroll and the tank opens up.
A shell holding mains pressure
Water sits in here at mains pressure, heated and cooled every day of its life. Most residential tanks are steel with glass fused to the inside, and that lining is the only thing keeping the steel out of the water. Everything below is what wears out first.
The one that stops it becoming a missile
A sealed tank under heat. This valve is the only thing between a failed thermostat and an explosion. Scale seizes it shut and almost nobody tests it.
The part that is supposed to corrode
On a glass lined steel tank, corrosion eats this rod instead of the steel. That trade is what gets a heater to a decade, and once the rod is gone the steel is next. Stainless, cement lined and plastic tanks carry no rod at all.
Where Florida water does its damage
Hard water drops calcium onto the element and buries it. It fires through the scale, runs hot, burns out early. You can hear it rumbling.
The ten minutes that adds years
Flush once a year and the sediment leaves before it buries the element. Highest return job on the unit. Swap the plastic valve for brass while you are there.
Leaking from the body, not a fitting
Once the tank body itself is weeping there is no repair, on any construction. Over ten years old and leaking from the shell rather than a fitting, a repair quote is a delay you pay for twice.
When we will not sell you a new one
Under eight years old and leaking from a fitting, a valve or an element gasket, that is a repair, and that is the quote you get. Over ten and leaking from the tank body, the shell itself has gone and there is nothing to patch.
Most heaters here do not die of age, they die of scale. Hard water buries the lower element and it cooks itself heating through it. One flush a year prevents nearly all of it.
Tankless Is A Real Option, And It Is Not Automatically The Right One
A tankless unit heats water as it passes through, so there is no tank standing full of hot water and no tank to rust out. That is the real advantage. The honest caveat is that a conversion is not a swap. Gas models need a larger gas line and a new vent, electric models need service capacity most older houses here do not have, so it starts with an assessment rather than a price.
If you already own one, the part nobody mentions when they sell it to you matters more. Tankless units scale up. Pasco and Hillsborough water is hard, the scale builds on the heat exchanger, and a unit that is never descaled loses efficiency and then fails early. Flushing it is routine work and we do it. If yours has never been flushed, that is the first thing to book, not a replacement.
Three Of The Four Tank Types Do Not Have An Anode Rod
Only a glass lined steel tank has one. Stainless, cement lined and composite tanks have nothing for a rod to protect, so on those there is no rod service to sell you.
Which one you own is printed on the data plate on the jacket. We read it before quoting anything, rather than assume. If someone has quoted you a rod, that is the first thing to check.
Sources, all manufacturer technical documents: A. O. Smith submittal sheet AOSTT35300, which specifies an interior glasslined with an alkaline borosilicate composition and lists a magnesium anode as a standard feature. HTP on the SuperStor Ultra, whose 316L stainless steel tank resists corrosion and eliminates the need for anode rods. Vaughn on HydraStone cement lining, a minimum half inch, a hundred times thicker than glass, zero anode rod needed. Rheem on the Marathon, a seamless blow molded polybutene tank that is impervious to rust and corrosion and needs no corrosion fighting anode rod. Yours is read off the data plate on the jacket rather than assumed.
From start to finish replacing my hot water tank was a very professional job the workers were very professional and the job was done quickly. I recommend them highly
Repair, or has it run out of road?
Five questions about what you can see and hear. The line between a repair and a replacement is drawn on this page, and this walks you to your side of it.
Water Heater Check
About 60 secondsHow old is the heater?
Eight to twelve years is the life of a glass lined steel tank, which is what most homes here have. Under eight is usually a repair, over ten changes the arithmetic.
If there is water, where is it coming from?
A fitting, a valve or a gasket is a part. The tank body itself is the shell, and a shell that is weeping cannot be repaired on any construction.
What is it doing?
Hard water drops calcium onto the element and buries it, so it fires through the scale and runs hot. You can hear it.
Have you checked the breaker and the reset?
The breaker is the cheapest fix there is. Behind the upper access panel on an electric unit there is a reset. If it trips again straight away, stop and call.
When was it last flushed?
Once a year in Florida. Flush and the sediment leaves before it buries the element.

The Part Of This You Can Actually Prevent
You just watched the anode rod corrode and the element disappear under scale. Both of those are on a clock, and the clock is reset by one visit a year. That visit is what the maintenance plan is.
Annual water heater flush, professional sediment removal, plus a visual inspection of exposed piping, shut-off valves and drainage. 10% member discount on anything found.
Gold · $599 a year The only plan that checks the two parts abovePremium flush including an inspection of the anode rod and the T&P safety valve, the two parts this page just walked you through. Water pressure testing, gas leak detection, 20% member discount and priority scheduling.
On a stainless, cement lined or plastic tank there is no anode rod to inspect, and the visit covers the flush and the relief valve instead. Plans are billed annually and cover one scheduled visit a year. Sign up by phone on 813-838-4193. Full detail on the maintenance plans page.
Two things to check first
The breaker
Check the breaker for the heater before anything else. It is the cheapest fix there is and it costs you nothing to look.
The reset button
Behind the upper access panel on an electric unit there is a reset. If it trips again straight away, stop and call. A repeatedly tripping element usually means water where it should not be.
