A water heater is one of the hardest working appliances in a home — running quietly every day, largely ignored, until something goes wrong. Most homeowners don’t think about water heater maintenance until they’re standing in a cold shower or dealing with a flooded utility room. But like any mechanical system that works continuously under heat and pressure, a water heater benefits from periodic attention — and the homeowners who give it that attention tend to get significantly more life out of their investment.
Most Water Heaters Never Get Serviced — Until They Fail
The average water heater gets installed and then forgotten. No annual checkup, no preventive attention, nothing until it stops working or starts leaking. That’s understandable — it’s out of sight, it does its job, and there’s no obvious reason to think about it. But water heaters that never get serviced tend to fail earlier than they should, cost more to operate in the years before they fail, and give out at the worst possible moments rather than on a convenient schedule. A little periodic attention is what separates a water heater that lasts its full lifespan from one that doesn’t.
What Sediment Is Doing Inside Your Tank Right Now
In most homes, the water supply carries dissolved minerals — calcium and magnesium primarily — that settle out of the water and accumulate at the bottom of the tank over time. That layer of sediment acts as insulation between the burner and the water, forcing the unit to work harder and run longer to heat the same amount of water. It also creates hot spots at the bottom of the tank that accelerate wear on the tank lining. Over time sediment buildup reduces efficiency, increases energy costs, shortens the unit’s lifespan, and produces the rumbling or popping sounds that many homeowners notice in older water heaters. Flushing the tank periodically removes that accumulation before it becomes a problem.
The Maintenance That Actually Extends a Water Heater’s Life
Water heater maintenance typically involves flushing sediment from the tank, inspecting the anode rod — a sacrificial metal rod that attracts corrosive elements and protects the tank lining — and checking the pressure relief valve, which is a critical safety component that needs to function correctly. The anode rod in particular is something most homeowners have never heard of, but it’s arguably the single most important factor in how long a tank water heater lasts. A depleted anode rod leaves the tank lining unprotected and accelerates corrosion from the inside out. Replacing it on schedule is one of the most cost-effective things a homeowner can do to extend the life of their water heater.
Tankless Units Need Attention Too
Tankless water heaters are often sold as low-maintenance alternatives to tank units — and they do have fewer moving parts. But they’re not maintenance-free. Scale buildup on the heat exchanger is the primary concern, particularly in areas with hard water. As minerals accumulate on the exchanger surfaces, the unit has to work harder to transfer heat efficiently, which reduces performance and can eventually cause component failure. Tankless units benefit from periodic descaling — a process that flushes the heat exchanger with a cleaning solution to remove mineral deposits. How often depends on local water hardness and usage patterns, but ignoring it entirely is how a tankless unit that should last twenty years starts having problems at ten.

Frequently Asked Questions
A higher water bill can indicate a leak, but it can also be caused by a running toilet or dripping faucet. Reviewing recent bills can help identify whether usage has spiked suddenly or crept up gradually — a sudden spike often points to a more significant issue, while gradual increases may indicate something smaller. If you're concerned, a plumber can help identify the source.
Water heaters should be drained and flushed at least once a year to prevent the buildup of sediment, calcium, and magnesium. This sediment accumulates at the bottom of the tank over time, reducing heating efficiency and accelerating wear on the tank lining. Regular flushing is one of the most effective ways to extend the life of a water heater.
The lifespan of a water heater depends on several factors — the type of unit, the quality of the original installation, how well it has been maintained, and the quality of the water running through it. Tankless units generally last longer than conventional tank heaters with proper upkeep. Homes with hard water or acidic water conditions tend to see shorter lifespans without treatment, as mineral buildup and corrosion accelerate wear. Regular maintenance is one of the most effective ways to get the most out of any water heater — and if yours is showing signs of age or underperforming, a professional evaluation is the best way to assess where things stand.
A water softener addresses hard water — water with high mineral content — by exchanging those minerals for sodium through a process called ion exchange. This protects pipes, appliances, and fixtures from scale buildup and improves soap lathering. A water filtration system addresses contaminants — sediment, chlorine, bacteria, heavy metals, and other substances — by physically filtering or treating the water. Some homes need one, some need the other, and some benefit from both. The right solution depends on what's actually in your water.
Seeds, bones, and anything that swells — such as pasta, rice, and wheat germ — should not go down the garbage disposal. Fibrous vegetables like celery, as well as grease, cooking oil, and coffee grounds, are also hard on disposals and drain lines.
Any mechanical device can fail over time and needs to be regularly checked. Backflow device manufacturers recommend annual testing, and the Plumbing Code requires it at minimum. A device that hasn't been tested may appear to be working while providing no actual protection — which is exactly why the requirement exists.
A backflow device is installed to protect your potable — or drinking — water from coming into contact with contaminants. When installed correctly and operating properly, it prevents contaminants from entering your water supply. This matters because under certain conditions — such as a sudden drop in water pressure — water can reverse direction through the pipes, potentially drawing contaminants back into the clean water supply. Backflow prevention is required by code in many situations.
Most water softeners benefit from a professional service visit every one to two years, though the right frequency depends on the age of the system, water hardness levels, and household usage. Regular servicing ensures the system is regenerating correctly, the resin bed is in good condition, and the unit is sized and adjusted appropriately for your water conditions. Between professional visits, keeping the brine tank stocked with salt is the primary ongoing maintenance task.
Septic systems should be inspected and pumped a minimum of once every three to four years. A full septic tank may allow unwanted solids to flow into the drain field — the part of the system that consists of a distribution box with a series of connected pipes, each allowing water to flow into a bed of stone that drains into the ground. If paper and other solids reach the drain field it becomes blocked and ineffective.
The most visible sign is blue-green staining on sinks, tubs, and fixtures — the result of copper leaching out of pipes as acidic water corrodes them. A metallic taste in the water, pinhole leaks in copper pipes, and premature failure of water-using appliances are also common indicators. These signs don't appear overnight — they develop gradually over time, which is why acidic water often goes undetected until the damage is already underway.
An acid neutralizer addresses water that is too acidic — raising its pH to prevent corrosion of pipes, fixtures, and appliances. A water softener addresses water that is too hard — removing calcium and magnesium minerals that cause scale buildup. The two systems treat different water quality problems, and some homes with well water need both. A water test is the best way to determine which issue — or combination of issues — is present in your water supply.
An acid neutralizer requires periodic replenishment of the neutralizing media as it dissolves into the water over time. How often depends on the pH of the water, the flow rate through the system, and the size of the tank — but annual service visits are a reasonable baseline for most systems. Regular servicing also includes inspecting the tank for channeling — a condition where water finds a path through the media without adequate contact time, which reduces effectiveness.
An acid neutralizer is a whole-home water treatment system that raises the pH of acidic water to a neutral or slightly alkaline level. It works by passing water through a tank filled with a neutralizing media — typically calcite or a blend of calcite and magnesium oxide — which dissolves slowly into the water and raises its pH. The result is water that is no longer corrosive to pipes, fixtures, and appliances. Acid neutralizers are most commonly needed in homes on well water where the local geology produces naturally acidic groundwater.
Simply carry out routine maintenance on your equipment and you will always have clear lines. At what temperature should I set my hot water tank? The optimum temperature is subjective. It all depends on your needs. The temperature should be set in your house based on who will use the facilities. For example, if you have young children I recommend lowering the maximum temperature to prevent accidental scalding.
Septic systems should be inspected and pumped a minimum of once every three to four years. A full septic tank may allow unwanted solids to flow into the drain field, which is the part of the system that consists of a distribution box, with a series of connected pipes. Each pipe allows water to flow into a bed of stone that drains into the ground. If paper and other solids flow into the drain field it becomes blocked and ineffective.

James B. (Charlottesville, Virginia)Going to use them for everything I can now including my HVAC maintenance. Replaced my sewer line for a great price. Camera'd my line for free and gave me a truly free estimate whether I used them or not. Job ended up being tougher than what was expected and not once did they bring up the possibility of changing from what they quoted me. Good group of guys right there. Chris and his crew know what they're doing.
Paul B. (Charlottesville, VA)As I commented on both Facebook and Angie's List this was a good experience. The service was performed as scheduled and well. There was a glitch in the billing, but your own people detected it and contacted me about it and took care of it on your own initiative. Greatly appreciated!
Johanne (Charlottesville, VA)Very efficient, quick diagnosis, and quick fix.
