Water Heater Service Cost at a Glance

If the visit turns up a repair, like an anode rod ($279), a heating element or thermostat ($349), or a gas control valve ($299), you get the price in writing first. You approve a written quote before any repair begins. See all of our water heater repair prices.

What the $89 Water Heater Flush Includes

Tank water heaters (gas or electric)

• Test the heating elements (electric) or the burner and ignition system (gas)
• Inspect the anode rod and tell you how much life it has left
• Test the temperature and pressure (T&P) relief valve
• Drain the tank and wash out the sediment Tampa hard water leaves on the bottom
• Check the tank, fittings, and connections for rust, leaks, or looseness

Tankless water heaters

• Flush the heat exchanger with descaler to remove mineral scale
• Test the ignition system and the pressure relief valve
• Inspect the unit and its connections for rust, leaks, or loose fittings

A tankless unit needs service isolation valves to be flushed properly. If yours does not have them, we will recommend adding them ($499) so it can be flushed now and every year after.

What the FREE Plumbing Inspection Covers

• Visible plumbing fixtures and fittings, checked for leaks or damage
• Water pressure at faucets and shower heads
• Under-sink piping, checked for leaks and corrosion
• Signs of water damage around plumbing connections and walls
• The water heater tank and its connections

The inspection covers the visible and accessible parts of your plumbing, not what is behind walls or under the slab. If we suspect a hidden leak, we will tell you and explain your leak detection options.

How Often Should You Flush a Water Heater in Tampa?

Once a year for most Tampa Bay homes. Our water is hard (City of Tampa water averaged 10.8 grains per gallon in 2024; see how hard Tampa water is), and those minerals settle on the bottom of the tank as sediment. On an electric tank, sediment buries the lower heating element and burns it out early. On a gas tank, it insulates the water from the burner, so the unit runs longer and works harder. If you hear popping or rumbling when the water heater runs, the sediment is already there. Tankless units need the same yearly descaling, because scale on the heat exchanger cuts hot water flow and can trigger error codes.

Is a Water Heater Flush Worth It?

For $89, yes. A yearly flush is the cheapest way to push a tank past the 8 to 10 years that Tampa hard water usually gives it, and the same visit catches the parts that fail first here: a worn anode rod, a weeping relief valve, or a scaled heating element. Catching a worn anode rod early costs $279. A new Rheem 50 gallon electric tank is $1,845 installed.

Before We Flush an Older Water Heater

We will always tell you this up front. On an older tank that has never been flushed, sediment can be the only thing plugging tiny rust holes in the bottom of the tank, and moving it can uncover a leak that was already there. If your tank is past about 10 years old or shows rust at the base, we will talk through that risk before we start, and if replacing it makes more sense, you get a FREE written estimate instead. If a tank is so clogged that the water will not drain, the extra sediment removal is priced before we do it.
