Usually sediment on the bottom of the tank, which water trapped underneath can boil through.

Water Heater Maintenance That Helps Prevent Breakdowns
Most water heaters run quietly for years, which makes them easy to forget until they fail. Routine maintenance means flushing built-up sediment, testing safety valves, inspecting parts that wear out and checking that the unit is venting and heating properly. It can help you catch problems early and may help a unit last longer, though results vary by unit, water quality and usage. Call or send a request and you'll be connected with an independent San Diego provider who can service your unit.
Maintenance is different from fixing a problem that's already happening. If your unit has already stopped working, see same day water heater repair, or emergency water heater repair for leaks and gas smells. If your unit is near the end of its life, ask about same day water heater replacement. You can also browse all water heater services or return to the San Diego homepage.
Signs Your Water Heater Needs Attention
A provider can confirm on site, but these are common signs that maintenance is due.
Less hot water than before
Sediment takes up tank space and coats heating parts, which can shorten your supply.
Discolored or rusty water
Can point to sediment or a worn anode rod, or to a corroding tank in more serious cases.
If it's the tank →Slow or weak hot water flow
Scale or a clogged filter can restrict flow, especially on tankless units.
Tankless repair →Relief valve dripping
Can signal excess pressure or a worn valve. It needs attention rather than being ignored.
Emergency help →Higher energy bills
A unit working harder because of sediment or scale may use more energy, though many things affect bills.
What Water Heater Maintenance Usually Includes
Exact scope depends on your provider and your unit, so confirm what's included before work starts.
Tank water heaters

Why Maintenance Matters, Especially in San Diego
As water is heated, dissolved minerals can settle out as sediment in a tank or as scale inside a tankless heat exchanger. San Diego's water is often described as hard, which can speed that buildup. Sediment can insulate the water from the burner or coat electric elements, making the unit work harder and wear out sooner. It can also cause noise and reduce how much hot water you get.
The anode rod is another part that quietly wears out. It corrodes in place of the tank steel, so once it's used up the tank itself is more exposed. Checking it is one reason routine service is often recommended. Ask your provider how your local water conditions and unit type affect the schedule they suggest.
How Often Should You Service Your Water Heater?
There's no single answer. These are general guidelines, and your manual and provider should guide you.
Tank units
A yearly check and flush is commonly recommended, but ask about your unit and water quality.
Tankless units
Descaling intervals vary by model and water hardness. Manufacturers usually list a recommended schedule.
Older units
Units around 10 years old or more may benefit from closer checks, or a conversation about replacement.
Heavy-use properties
Rentals, restaurants and other busy sites may need more frequent service.
Commercial service →Have gas or electric specific concerns? See gas water heater repair or electric water heater repair.
DIY Checks vs Professional Service
Some upkeep is reasonable for homeowners. Gas, power and hot water call for care.
Reasonable to do yourself
- Checking around the unit for drips, rust or moisture
- Listening for new noises and noting changes in hot water
- Checking the temperature setting against your manual
- Keeping the area around the unit clear
Best left to a qualified provider
- Flushing a tank if you're unsure how to do it safely
- Replacing an anode rod, which can be hard to remove
- Testing or replacing a relief valve
- Gas, wiring, venting and tankless descaling work
Homeowners are responsible for verifying the licensing, insurance and qualifications of any provider they hire.

When Maintenance Turns Up a Bigger Problem
A maintenance visit sometimes finds something that needs more than a flush. A worn part can usually be repaired, while a corroded tank or a leak from the tank body generally can't. Your provider should explain what they found, show you the options and give you a price before doing more work.
For a fault on a working unit, see same day water heater repair. If the tank has failed or the unit is old and repairs keep repeating, see same day water heater replacement, or consider tankless water heater installation. Our blog also has more tips.

Water Heater Maintenance FAQ
How often should a water heater be serviced?
Many manufacturers recommend an annual check, and flushing a tank unit about once a year is commonly advised. The right schedule depends on your unit, how much you use it and your water quality. Your provider can recommend a schedule and your unit's manual may list one.
What does water heater maintenance include?
For tank units it typically includes flushing sediment, testing the relief valve, inspecting the anode rod and checking connections, controls and venting. Tankless units usually need descaling and inlet filter cleaning. Exact scope depends on your provider and unit.
How much does water heater maintenance cost?
It depends on the type of unit, its size and condition, and what the service includes. A basic flush is typically a different job from a full inspection or tankless descaling. Ask for the price and what's included before any work begins.
Does hard water affect my water heater?
It can. Minerals in hard water can build up as sediment in tank units and as scale in tankless units, which may reduce performance and shorten the life of parts. San Diego's water is often described as hard, so ask your provider what schedule suits your unit.
Does a tankless water heater need maintenance?
Yes. Tankless units commonly need periodic descaling or flushing and inlet filter cleaning, especially with hard water. Manufacturers list recommended intervals, and a provider can advise on a schedule for your unit.
Can I flush my water heater myself?
Many homeowners do, but the water is hot and gas or electric power must be handled correctly. Turn off power or gas first and follow your manual. If you're unsure, or the drain valve is stuck or leaking, call a qualified provider.
Will maintenance extend the life of my water heater?
Regular maintenance can help catch problems early and may help a unit last longer, but results vary by unit, water quality and usage. It can't reverse existing damage such as a corroded tank.
