That first ice-cold shower, the sudden banging and popping from the utility closet, or an unexplained jump in your utility bill is usually the moment Memphis homeowners realize their water heater has been quietly wearing out for years. Until then, the tank just sits in a corner doing its job, so it is easy to forget it is a hard-working appliance with internal wear.
For many families, hot water is something you only think about when it is gone. Inside that tank, heat, pressure, sediment, and minerals are all at work every single day. Without routine care, they slowly rob your heater of efficiency and reliability. A simple maintenance routine costs far less than a surprise replacement, and it can give you much more control over comfort and monthly bills.
At Smith's Plumbing, Heating & Air, we have been working on water heaters in Memphis and the surrounding communities since 2010, under the leadership of a Tennessee and Mississippi Master Plumber. Our technicians spend every week inside local homes, opening up tanks and seeing the same preventable issues: inches of sediment, worn-out anode rods, and safety valves that have never been tested. In this guide, we explain what routine water heater maintenance really does for you and why it matters so much in Memphis.

Why Memphis Water Heaters Need Routine Maintenance
Many homeowners treat a water heater like a light bulb, install it and forget it until it fails. A tank water heater is not designed to be a no-maintenance appliance. Manufacturers generally expect the tank to be flushed and inspected periodically, and they build in components, such as anode rods, that assume someone will check and replace them before they are completely used up.
In the Memphis area, our water often carries sediment and minerals that settle out once they hit the bottom of a hot tank. Over time, that grit forms a dense layer at the bottom of the tank where the burner or lower element is trying to heat water. Instead of transferring heat efficiently into clean water, the heater has to fight through mud and mineral buildup. That extra effort means more energy use and more wear on the tank.
We routinely see the same pattern in local homes. A heater that has never been drained or inspected starts making rumbling noises, takes longer to recover between showers, or struggles to keep up when relatives visit. Homeowners usually describe the failure as sudden, but when we open the drain, several inches of sludge pour out. After more than 14 years of servicing water heaters around Memphis, we know that routine maintenance is often the difference between a system that quietly does its job and one that surprises you years before you expected to replace it.
What Really Happens Inside an Unmaintained Water Heater
Inside every tank water heater, there is a constant battle between heat, metal, water, and minerals. When maintenance is ignored, that battle usually has only one winner: corrosion. The first player in this story is sediment. Tiny particles in your water supply settle to the bottom of the tank, where the water is hottest. As they build up, they form a thick blanket that traps heat underneath. That trapped heat creates steam bubbles that force their way up through the sediment, which is what causes the popping and rumbling sounds many Memphis homeowners hear.
Along with sediment, minerals in the water form scale. If you have an electric water heater, these minerals often attach themselves to the heating elements. Instead of a smooth metal surface transferring heat efficiently into water, you get a crusty coating that acts like insulation. The elements stay hotter for longer, and they are more likely to burn out early. Inside the tank walls, scale and heat together can weaken the metal over time and make it more likely to leak.
There is one component whose entire job is to absorb corrosion so your tank does not have to, the anode rod. This rod runs down into the tank and is made from a metal that is more attractive to corrosion than the steel tank itself. As long as the anode rod is intact, it sacrifices itself and helps keep the tank walls protected. Once it is fully consumed, the tank body becomes the next target. When we service water heaters in Memphis that have never been maintained, we often pull out an anode rod that is completely gone or so thin it snaps in our hands, which tells us the tank has been unprotected for years.
There is also a safety side to all this. Every water heater has a temperature and pressure relief valve, often called a T&P valve. Its job is to open if pressure or temperature gets too high, so the tank does not turn into a sealed pressure vessel. If that valve is never tested and maintained, it can seize up or leak. During maintenance, our technicians check the T&P valve for signs of seeping, corrosion, or sticking, because neglect here is not just a comfort issue, it is a safety concern.
How Routine Maintenance Extends Water Heater Life
When we talk about maintenance, we are not talking about a quick look at the tank from across the room. A proper maintenance visit tackles the sources of wear directly. One key step is flushing the tank. By attaching a hose to the drain and running water through until it comes out clear, we wash out much of the sediment that has settled at the bottom. Less sediment means the burner or elements can heat water directly instead of heating through a layer of mud, so they do not have to run as long or as hard.
Another central task is inspecting the anode rod. If we pull the rod and see that it is mostly consumed, we can discuss replacing it. Swapping in a new anode rod helps restore corrosion protection for the tank walls. This is a simple, cost-effective way to slow rust inside the heater and can make the difference between a tank that fails at the low end of its expected lifespan and one that makes it much closer to the high end.
During maintenance, our technicians also look at thermostat settings, check visible fittings for small leaks, and test the T&P valve. Catching a tiny drip at a connection or a seeping drain valve during a scheduled visit is far better than discovering it after it has soaked the floor of a closet or attic. Adjusting the thermostat to an appropriate setting helps reduce scald risk and stress on the heater while still giving your family comfortable hot water.
In our experience across Memphis, water heaters that receive regular flushing and inspection tend to last closer to the upper end of their typical lifespan, while similar models that are never maintained often show serious problems earlier. There are always variables, and no one can promise a specific number of extra years, but maintenance stacks the odds in your favor. Because Smith's Plumbing, Heating & Air technicians arrive with fully stocked service vans, we can usually handle small repairs, such as valve replacements or anode swaps, during the same visit, which further protects your investment.
Energy Bills, Comfort, and Other Everyday Benefits
Most homeowners feel the impact of neglect long before the tank actually fails. One of the first places it shows up is on your utility bill. When sediment lines the bottom of the tank or scale coats electric elements, your heater has to run longer to produce the same amount of hot water. Those extra run times show up as higher gas or electric charges every month. Routine maintenance that removes sediment and scale helps your heater heat water more efficiently, which can ease that upward pressure on bills.
Comfort is another everyday benefit. A neglected water heater often struggles to keep water temperature consistent. You may notice the shower going hot and cold, or that it takes longer for hot water to reach the tap. Those rumbling or popping noises you hear are usually steam bubbles forced through sediment, which is a direct sign that the heater is working against that internal buildup. After a thorough flush and check, many of our Memphis customers report quieter operation and more stable temperatures.
Thermostat settings are part of this picture too. During maintenance, we verify that the thermostat is set to an appropriate temperature for your household. A setting that is too high not only increases scald risk, especially for children and older adults, it also makes the heater work harder than it needs to and accelerates mineral buildup. A setting that is too low can leave you with lukewarm showers and dishes that do not get clean. Finding the right balance is something our technicians discuss with you during a visit so comfort, safety, and efficiency line up with how your family actually uses hot water.
The combination of lower stress on the heater, quieter operation, and fewer surprises adds up to peace of mind. Instead of wondering whether today is the day the water goes cold, you know there is a plan in place and that a professional has recently looked over the system. For many Memphis homeowners, that predictable comfort is as valuable as any savings on their utility bill.
How Often Memphis Homeowners Should Schedule Water Heater Maintenance
One of the most common questions we hear is how often a water heater needs maintenance. For many Memphis-area homes, an annual professional maintenance visit is a good starting point. Our water supplies tend to carry enough sediment and minerals that a yearly flush and inspection keep buildup under control and let us spot developing issues in time to address them while they are still small.
Some homes benefit from more frequent attention. If your household uses a lot of hot water every day, for instance, a large family with multiple showers and laundry loads, your heater is working harder and accumulating sediment more quickly. Older units, or heaters installed in tight closets or attics where heat builds up around the tank, may also need closer monitoring to stay safe and efficient. No two homes are identical, but usage and environment both affect how fast the inside of a tank changes.
We also work with many homeowners who call us after several years with no maintenance history at all. If your heater is older or has never been flushed, that does not mean maintenance is pointless. In many cases, a careful first maintenance visit can improve performance and give us a clear picture of how much life is left. After more than a decade of inspecting water heaters across the Memphis area, we have found that yearly checks are a practical balance between cost and protection for most households, and we can fine-tune that schedule once we have seen your specific setup.
What Homeowners Can Check and What to Leave to a Plumber
Many Memphis homeowners want to know what they can safely do themselves and where a licensed plumber really is necessary. There are a few simple checks that are low risk and very helpful. Every so often, take a look around the base of your water heater for any signs of water, dampness, or rust trails. Listen for new or louder noises when the heater is firing. Pay attention to changes in how long it takes for hot water to reach a faucet or how stable the temperature feels during a shower. These observations give you early clues that something is changing.
Beyond visual and sound checks, it is best to be cautious. Tasks that involve gas, electricity, or pressure should be left to a professional. Testing the T&P valve, for example, can release hot water under pressure if it is done incorrectly or if the valve sticks. Working on gas burners, gas connections, and venting requires training and the right tools to avoid leaks and combustion problems. Electric heaters use high-voltage circuits that should be de-energized, tested, and handled correctly before elements or thermostats are accessed.
We sometimes meet homeowners who tried to flush their own tank, only to find the drain valve clogged with sediment or leaking afterward. What seems like a simple “hook up a hose and open a valve” project can become a headache if that valve has not been touched in years. Our technicians are trained to safely shut down the heater, relieve pressure, and deal with stuck or leaking valves. Because we arrive in fully stocked vans, we can replace faulty parts on the spot in most cases, which is not something most homeowners can do on a Saturday afternoon.
During a maintenance visit, we also walk you through what we are doing and what we see. That way, you still feel involved and informed without being the one holding the wrench. With upfront pricing and a clear explanation before we start work, you know what to expect and can make informed decisions about any recommended repairs or upgrades.
Signs Your Water Heater May Be Beyond Maintenance
Routine maintenance can do a lot, but it cannot turn back the clock on a tank that is already at the end of its life. A key sign is age. If your water heater is well past the typical life range, especially if it has had no maintenance, there is a higher chance that the tank walls are already thin from corrosion. Visible rust on the outside of the tank body, not just on fittings, is another warning that the metal itself is deteriorating.
Leaks are another dividing line. A small drip from a drain valve, T&P valve, or pipe connection is often repairable. A steady leak from the bottom of the tank, or water weeping through the tank body itself, usually means the internal shell has failed. No amount of flushing or anode replacement can repair a breached tank wall. In those situations, continuing to run the heater can risk a larger leak and water damage to nearby floors, walls, or ceilings.
We also look at the pattern of problems. If your heater has needed repeated repairs in a short period, such as multiple element replacements, recurring pilot issues, or frequent resets, that can be a sign that the tank is aging out. Maintenance may still improve safety and short-term performance, but it might not be the best use of your budget over the next few years. Our goal during any maintenance visit is to be honest about where your heater stands on that curve.
As a family-owned company built on long-term relationships with Memphis homeowners, we do not believe in endlessly patching a failing heater just to sell another visit. If our inspection shows that a replacement would be more responsible, we explain why, show you what we are seeing, and talk through options. For larger projects, such as replacing a tank in a tight closet or attic, we can discuss available financing options that help spread the cost, so you are not forced to choose between living with a risky heater or paying all at once.
