Regular water heater maintenance can help catch problems early, keep your system performing reliably, and reduce the chance of an unexpected loss of hot water. Suburban Plumbing Experts provides professional water heater maintenance throughout Chicago and the surrounding suburbs for both traditional tank and tankless systems.

Our plumbers inspect the condition of your water heater, perform appropriate maintenance, and explain anything that needs attention. Whether your system has been serviced regularly or hasn't been checked in years, we'll give you a straightforward assessment of what we find.

Water Heater Maintenance in Chicago

Water heaters work every day, and normal use can lead to sediment, mineral buildup, worn components, leaks, and other problems over time. Regular maintenance gives you an opportunity to address those issues before they become a larger repair.

Maintenance needs vary by the type of water heater and the equipment itself. Tank and tankless systems require different service, and gas and electric units have different components that need to be checked.

We provide maintenance for:

• Traditional tank water heaters
• Tankless water heaters
• Gas water heaters
• Electric water heaters
• Residential and commercial systems

For most homes, annual maintenance is a good starting point. The appropriate schedule can depend on the equipment, water conditions, usage, and manufacturer recommendations.

Tank Water Heater Maintenance

Traditional tank water heaters can collect sediment over time. Mineral buildup can affect heating performance and contribute to problems inside the tank.

Depending on the condition of the system, maintenance may include:

• Flushing sediment from the tank
• Inspecting the anode rod
• Checking the temperature and pressure relief valve
• Inspecting connections and valves
• Checking for leaks or corrosion
• Inspecting heating components
• Checking the overall condition of the water heater

If we find a problem that goes beyond routine maintenance, we'll explain what we found and discuss your options. That may include water heater repair or water heater replacement, depending on the condition of the equipment.

Tankless Water Heater Maintenance

Tankless water heaters need different maintenance than traditional tank systems. Mineral scale can build up on the heat exchanger and affect water flow and heating performance.

Tankless maintenance may include flushing and descaling the heat exchanger, cleaning filters, inspecting connections, checking system operation, and looking for signs of developing problems.

Regular maintenance is particularly important when mineral buildup is a concern. The goal is to keep the system operating properly and identify problems before they become more expensive repairs.

If you're considering a tankless system or want to compare it with a traditional tank water heater, see our guide to tankless vs. tank water heaters in Chicago.

What We Check During Water Heater Maintenance

A professional maintenance visit is more than simply looking at the outside of the water heater. We check the components that affect the system's operation and look for signs of leaks, corrosion, wear, or other problems.

The exact inspection depends on your water heater, but may include:

Sediment and Mineral Buildup

Tank water heaters can accumulate sediment at the bottom of the tank. Tankless systems can develop scale inside the heat exchanger. The appropriate cleaning or descaling procedure depends on the type of equipment.

Safety Components

We check important safety components and connections as part of the maintenance process. For gas systems, that can include inspecting the burner and venting components. Electric systems have different heating and electrical components that require inspection.

Leaks and Corrosion

We look around the water heater, valves, connections, and surrounding plumbing for signs of leakage or corrosion. Finding a problem early gives you an opportunity to address it before it causes more damage.

Heating and Temperature Controls

We evaluate the components responsible for heating the water and controlling its temperature. If the system isn't heating properly or hot water performance has changed, maintenance can help identify the cause.

Overall Condition

We also consider the age, condition, usage, and performance of the water heater. If the equipment is showing significant wear or repeated problems, we'll explain whether continued maintenance and repair make sense or whether replacement should be considered.

How Often Should a Water Heater Be Maintained?

For many residential water heaters, annual maintenance is a reasonable starting point. Manufacturers can have different maintenance requirements, so the equipment's installation and manufacturer's recommendations should also be considered.

Some systems may need attention more frequently depending on water quality, hot water usage, age, or the amount of mineral buildup.

Tankless systems also have specific maintenance requirements, including periodic descaling when mineral buildup is a concern.

If you aren't sure when your water heater was last serviced, you don't necessarily need to wait for a problem. We can inspect the system and recommend an appropriate maintenance schedule based on its condition.

Signs Your Water Heater May Need Service

You don't have to wait until the water heater stops working completely. Changes in performance can be an early indication that the system needs attention.

Common warning signs include:

• Hot water that runs out faster than usual
• Water temperatures that fluctuate
• Longer heating times
• Popping, banging, or rumbling sounds from a tank
• Rust or corrosion around the unit
• Moisture or water around the water heater
• Reduced hot water flow from a tankless system
• Higher energy use without a clear change in usage

These symptoms can have different causes, so maintenance should start with an inspection rather than assuming a particular component has failed.

Our guide to common water heater warning signs in Chicago explains what some of these changes can mean.

Water Heater Maintenance for Older Chicago Homes

Older Chicago homes can have older plumbing connections, aging water heaters, and equipment that has been repaired or modified over the years. Regular maintenance gives you a chance to see the current condition of the system instead of waiting for a failure.

If the water heater is still in good condition, routine maintenance may help keep it operating reliably. If the equipment is showing significant corrosion, leaking, repeated component failures, or other signs of deterioration, we'll explain what we find and discuss whether repair or replacement is the better option.

If you're unsure whether your water heater is approaching replacement, our water heater replacement guide can help you understand the warning signs.

Why Professional Water Heater Maintenance Matters

Water heater maintenance involves components that can include gas, electricity, heated water, pressure, burners, heating elements, safety controls, and venting. The maintenance required depends on the equipment and its installation.

A professional inspection can help identify problems that aren't always obvious from the outside. It also gives you a clearer picture of the condition of your water heater and whether it needs routine maintenance, repair, or eventual replacement.

At Suburban Plumbing Experts, we'll explain what we find rather than recommending work simply because it's on a checklist. If something needs attention, you'll know what the problem is and what your options are.

Water Heater Maintenance FAQs

How often should I have my water heater maintained?

Annual maintenance is a good starting point for many residential systems, but the right schedule depends on the type of water heater, manufacturer recommendations, water conditions, usage, and equipment condition.

Does a tank water heater really need to be flushed?

Tank water heaters can collect sediment over time. Flushing can remove accumulated sediment when the equipment and its condition make flushing appropriate.

Do tankless water heaters need maintenance?

Yes. Tankless systems can develop mineral scale inside the heat exchanger and may require periodic flushing and descaling. Other components, filters, and system operation should also be checked.

Can maintenance prevent my water heater from breaking down?

Maintenance cannot prevent every failure, but it can help identify sediment, corrosion, leaks, worn components, and other developing problems before they become larger issues.

Is water heater maintenance different for gas and electric units?

Yes. Gas and electric water heaters have different components and safety considerations, so the inspection and maintenance performed will depend on the type of system.

My water heater seems to be working fine. Should I still have it checked?

If you don't know when it was last serviced, an inspection can help establish its current condition and identify problems that may not yet be obvious.
