Water Heater Maintenance at a Glance
- Both tank and tankless water heaters need routine maintenance.
- Traditional tanks can collect sediment near the bottom.
- Tankless systems can develop mineral deposits inside the heat exchanger.
- Flushing or descaling helps remove this buildup.
- An inspection can uncover leaks, corrosion, pressure concerns, and worn components.
- Annual maintenance is a common recommendation, although the right schedule depends on the equipment, household use, and manufacturer instructions.
- A leaking tank, gas odor, loss of hot water, or significant corrosion requires prompt repair rather than routine maintenance.
Why Water Heater Maintenance Matters
Your water heater works every day to provide hot water for showers, dishes, laundry, cleaning, and other household needs. Because it usually operates quietly in a garage, basement, closet, or utility room, it is easy to forget about until something goes wrong.
Changes can still take place inside a water heater that appears to be working normally.
Traditional water heaters store a supply of heated water. Sediment can gradually settle at the bottom of the tank as fresh water enters and is heated.
Tankless water heaters do not store a large volume of water, but water passes through narrow internal waterways and a heat exchanger. Mineral deposits can accumulate in these areas over time.
Routine water heater maintenance may help:
- Remove sediment and mineral buildup
- Support consistent hot-water performance
- Reduce unnecessary strain on the system
- Identify small leaks or deteriorating connections
- Detect corrosion and other signs of wear
- Verify that safety components are in place and functioning
- Give homeowners time to plan for future repairs or replacement
Maintenance cannot guarantee that a water heater will never break down. It can provide valuable information about its condition and help address manageable concerns before they become more disruptive.
Tank Water Heater Maintenance
Traditional water heaters continually heat and store a supply of water. Over time, sediment can accumulate near the bottom of the tank.
The amount of buildup varies from home to home. The age of the water heater, household use, water conditions, temperature settings, and previous maintenance history can all affect what is found inside.
Professional tank water heater maintenance may include:
- Inspecting the tank and surrounding area
- Checking visible water and gas connections
- Looking for moisture, corrosion, or rust
- Evaluating the drain valve
- Inspecting the temperature and pressure relief valve
- Checking the expansion tank when one is installed
- Reviewing the temperature setting
- Flushing sediment from the tank when appropriate
- Inspecting the burner or heating components
- Checking applicable venting
- Testing the water heater after service
An experienced plumber should inspect an older or previously neglected tank before attempting to flush it. Opening an aging or deteriorated drain valve can sometimes reveal or create a leak, and a heavily corroded tank may no longer be an appropriate candidate for routine maintenance.
Does Every Tank Water Heater Need to Be Flushed?
Flushing is a common part of tank water heater maintenance, but it is not always as simple as attaching a hose and opening the drain.
A newer water heater that has received consistent maintenance may be a good candidate for regular flushing. An older tank that has never been maintained should be inspected first.
The plumber may consider:
- The age of the tank
- The condition of the drain valve
- Visible corrosion
- Evidence of an existing leak
- The amount of sediment present
- Whether the tank has been flushed before
- The general condition of the installation
Aaron Services will evaluate the system and explain the appropriate maintenance options before beginning additional work.
Tankless Water Heater Maintenance
Tankless water heaters heat water on demand rather than storing dozens of gallons of hot water. That does not make them maintenance-free.
Mineral deposits can accumulate inside the heat exchanger and internal waterways. Over time, this buildup may affect water flow, temperature consistency, efficiency, or system operation.
Professional tankless water heater maintenance may include:
- Inspecting the unit and visible connections
- Flushing or descaling the heat exchanger
- Cleaning accessible inlet filters
- Reviewing stored error codes
- Inspecting venting and combustion components when applicable
- Checking temperature and pressure settings
- Looking for leaks or corrosion
- Testing operation after maintenance
Tankless water heaters should be serviced according to the instructions for the specific brand and model. Our more detailed explanation of tankless water heater flush and maintenance covers how mineral buildup affects these systems and what homeowners can expect from professional service.
Aaron Services maintains major tankless brands, including Navien, Rinnai, Noritz, Rheem, Bosch, Takagi, and others.
Tank vs. Tankless Water Heater Maintenance
Both tank and tankless water heaters benefit from maintenance, but the process is not identical.
Traditional Tank Water Heaters
A tank water heater stores heated water. Sediment can settle at the bottom, where it may contribute to noise, reduced capacity, or additional strain on the system.
Maintenance commonly focuses on:
- Flushing the tank when appropriate
- Inspecting the tank for corrosion
- Checking valves and connections
- Reviewing safety components
- Inspecting heating or combustion components
Tankless Water Heaters
A tankless unit heats water as it moves through the system. Mineral deposits can collect inside the heat exchanger and restrict internal waterways.
Maintenance commonly focuses on:
- Flushing or descaling the heat exchanger
- Cleaning filters
- Checking error-code history
- Inspecting venting and combustion
- Confirming proper water flow and temperature
Neither type is completely maintenance-free. The right service depends on the equipment, its age, manufacturer requirements, water conditions, and previous maintenance history.
How Often Should a Water Heater Be Maintained?
Annual water heater maintenance is a common recommendation for both traditional and tankless systems. However, the best schedule may vary depending on:
- The manufacturer’s instructions
- Whether the system is tank or tankless
- The age of the equipment
- Household hot-water use
- Water quality and mineral content
- Previous maintenance history
- Warranty requirements
- Changes in performance
- Whether the home uses filtration or water treatment
A large household that uses substantial amounts of hot water may place different demands on a system than a smaller household. A unit with no documented service history may also need a more detailed initial evaluation.
When scheduling, it is helpful to provide the brand, approximate age, and most recent maintenance date when that information is available.

Signs Your Water Heater Needs Attention
A water heater does not always fail without warning. Changes in performance can indicate that the system needs maintenance, repair, or further evaluation.
Watch for:
- Hot water running out sooner than usual
- Water taking longer to heat
- Inconsistent temperatures
- Popping, rumbling, crackling, or banging sounds
- Reduced hot-water flow
- Rusty or discolored hot water
- An unusual odor from the hot water
- Visible corrosion around valves or connections
- Error codes on a tankless unit
- Moisture or dripping near the equipment
- No record of maintenance within the past year
Some symptoms may be related to sediment or mineral buildup. Others can point to a failed heating element, gas component, thermostat, valve, pressure concern, or aging tank.
Our water heater repair service addresses specific problems such as no hot water, inconsistent temperatures, minor leaks, failed components, and tankless error codes.
What Should You Do If the Water Heater Is Leaking?
A leaking water heater should not be treated as routine maintenance. Water can spread quickly and damage flooring, drywall, storage, and nearby belongings.
When a water heater is leaking:
- Turn off its energy source when it is safe to do so.
For an electric water heater, turn off the appropriate breaker. For a gas water heater, follow the manufacturer’s instructions for turning off the gas control. - Close the cold-water supply valve.
This valve is usually on the cold-water line entering the water heater. If it will not close or cannot be located, shut off the main water supply to the house. - Stay away from standing water near electrical equipment.
- Call an experienced plumber promptly.
Leaks from fittings, valves, or connections may sometimes be repairable. A tank that has corroded and begun leaking generally needs to be replaced.
Our guide to a water heater leaking from the bottom explains common sources of water around the unit and the steps homeowners should take to limit damage.

Can Maintenance Help a Water Heater Last Longer?
Maintenance is one factor that can affect the useful life of a water heater. Installation quality, equipment type, household demand, operating temperature, water conditions, and the quality of previous repairs also matter.
Traditional tank water heaters commonly last approximately 8 to 12 years. Tankless water heaters can often last 15 to 20 years or longer when properly installed and maintained. These are general ranges rather than fixed expiration dates.
Routine maintenance may help a system reach more of its expected service life by reducing buildup and identifying developing concerns. It also gives homeowners an opportunity to plan ahead instead of waiting for an aging system to fail unexpectedly.
Our discussion of how long a water heater lasts explains the factors that affect lifespan and the signs that repair or replacement may be approaching.
Water Heater Maintenance or Repair?
Maintenance is intended for a water heater that is generally operating but needs routine care and inspection. Repair is intended to correct a specific problem.
Maintenance May Be Appropriate When:
- The water heater is operating normally
- It has been approximately a year since its last service
- You want to establish a regular maintenance schedule
- The manufacturer recommends periodic service
- You recently purchased the home and do not know the maintenance history
- You want the unit inspected before heavier seasonal use
Repair May Be Appropriate When:
- There is no hot water
- The temperature changes unexpectedly
- The tank or a connection is leaking
- A breaker repeatedly trips
- A pilot light will not stay lit
- A tankless unit displays an error code
- Hot-water pressure or flow has declined
- The unit is making new or unusually loud noises
When an older unit is leaking, badly corroded, or becoming unreliable, replacement may make more sense than continued repairs. Aaron Services provides a complete range of water heater services, including maintenance, repair, tankless service, and replacement options.
What Does Water Heater Maintenance Cost?
The cost of water heater maintenance depends on the type and condition of the system and what is needed during the appointment.
Pricing can be affected by:
- Tank or tankless design
- Gas or electric operation
- Number of water heaters
- Brand and model
- Accessibility
- Maintenance history
- Condition of valves and connections
- Whether tankless service valves are installed
- Whether repairs or replacement parts are needed

Frequently Asked Questions About Water Heater Maintenance
Do water heaters really need maintenance?
Both tank and tankless water heaters benefit from routine maintenance. Traditional systems can collect sediment, while tankless heat exchangers can develop mineral buildup. Maintenance also creates an opportunity to check for corrosion, leaks, pressure concerns, and worn components.
How often should a water heater be serviced?
Annual maintenance is a common recommendation. The right schedule depends on the type of water heater, manufacturer requirements, household demand, water conditions, and previous service history.
Does a tankless water heater need to be flushed?
Tankless water heaters commonly require periodic flushing or descaling to remove mineral deposits from the heat exchanger. The recommended schedule depends on the model, water conditions, and manufacturer instructions.
What happens if a water heater is not flushed?
Sediment or mineral buildup can accumulate inside the system. Depending on the type of heater, that buildup may contribute to noise, reduced flow, inconsistent temperatures, increased strain, or premature wear.
Should an old water heater be flushed if it has never been maintained?
It should be inspected first. An aging drain valve can leak after it is opened, and significant sediment or corrosion may affect the safest maintenance approach.
Can maintenance fix a leaking water heater?
Maintenance will not repair a tank that has rusted through. Some leaks from valves, fittings, or connections may be repairable, but a leaking tank generally requires replacement.
Is water heater maintenance the same as repair?
No. Maintenance is routine care for a generally functioning system. Repair addresses a specific problem such as no hot water, a leak, a failed component, or a tankless error code.
