Signs Your Water Heater Needs Professional Attention

Water heaters often provide warning signs before they stop working completely. Addressing these problems early may help prevent water damage, higher utility costs, or a complete loss of hot water.

• The water does not become hot.
• Hot water runs out faster than normal.
• The water temperature changes without warning.
• The unit makes popping, rumbling, or banging sounds.
• Water is collecting around the tank.
• The hot water looks rusty or cloudy.
• The water has an unusual odor.
• The pilot light will not remain on.
• The circuit breaker trips repeatedly.
• The water heater takes longer to recover.
• The unit has visible rust or corrosion.
• Energy costs have increased without a clear reason.

No Hot Water

A complete loss of hot water can have several causes. The problem may involve the thermostat, heating element, gas supply, burner, pilot light, electrical circuit, or another part of the system.

Common Causes in Electric Water Heaters

• A tripped circuit breaker
• A failed heating element
• A damaged thermostat
• Loose or damaged wiring
• A failed high-limit safety switch

Common Causes in Gas Water Heaters

• A pilot light that has gone out
• A faulty ignition system
• A damaged gas valve
• A dirty or failed burner
• A gas supply problem
• Improper venting

Do not attempt to repair gas controls or electrical parts unless you have the required training. A professional can test the system and identify the source of the problem.

Fluctuating Water Temperatures

Hot water that suddenly becomes cold or changes temperature during use may point to a thermostat problem, heating element failure, sediment buildup, damaged dip tube, or undersized water heater.

In tankless systems, changing temperatures may be caused by mineral buildup, low water flow, sensor problems, incorrect sizing, or several fixtures using hot water at the same time.

A plumber can inspect the unit and determine whether maintenance, repair, adjustment, or replacement is needed.

Hot Water Runs Out Too Quickly

A water heater may produce some hot water but fail to provide enough for the household. This can become noticeable when several people shower, the dishwasher runs, or the washing machine uses hot water.

Possible Causes Include:

• The tank is too small for the household.
• Sediment has reduced the available tank capacity.
• One heating element has failed.
• The thermostat is set incorrectly.
• The dip tube is damaged.
• Hot water demand has increased.
• The unit is aging and losing efficiency.

A larger water heater is not always the only solution. A plumber can review hot water demand and determine whether the current unit has a repairable problem.

Water Heater Leaks

Water around a water heater should never be ignored. The leak may come from a loose connection, shutoff valve, drain valve, pressure relief valve, expansion tank, or the water heater tank itself.

Common Leak Locations

• Hot and cold water connections
• Flexible supply lines
• Drain valve
• Temperature and pressure relief valve
• Expansion tank
• Tank seams
• Bottom of the water heater

A leaking fitting or valve may be repairable. A tank that is leaking because of internal corrosion will usually need to be replaced.

What to Do When a Water Heater Is Leaking

1. Turn off the water supply.
   Close the shutoff valve above the unit if it can be reached safely.
2. Turn off the energy source.
   Shut off the circuit breaker for an electric unit or follow safe gas shutoff procedures for a gas model.
3. Keep people away from electrical hazards.
   Do not enter standing water near wiring or electrical equipment.
4. Move belongings away from the water.
   Protect nearby boxes, furniture, flooring, and personal property.
5. Call a plumbing professional.
   Explain where the water appears to be coming from and whether the leak is active.

Rusty, Cloudy, or Smelly Hot Water

Discolored or unusual-smelling hot water may be related to the water heater, plumbing pipes, water source, or bacteria inside the system.

Rusty or Brown Hot Water

Rust-colored hot water may come from corrosion inside the tank, a worn anode rod, or older plumbing lines. If only the hot water is discolored, the water heater may be the likely source.

Cloudy Water

Cloudy water may contain air bubbles, mineral sediment, or debris. In some cases, the water clears after sitting in a glass for a few minutes. Ongoing cloudiness should be inspected.

Unpleasant Odors

A sulfur-like or rotten egg odor in hot water may be caused by bacteria, water chemistry, the anode rod, or another water quality issue.

A plumber can inspect the unit and help determine whether flushing, cleaning, anode replacement, water treatment, or another solution may be needed.

Water Heater Noises

Popping, cracking, rumbling, or banging sounds often point to sediment buildup inside a tank water heater. Water may become trapped beneath the sediment and create noise as it heats.

Other sounds may come from:

• Loose heating elements
• Changing water pressure
• Thermal expansion
• Water hammer
• Worn valves
• Mineral scale

Continued sediment buildup may reduce heating performance and shorten the life of the tank.

Can a Water Heater Burst?

A properly installed water heater includes safety controls designed to manage temperature and pressure. However, serious problems can occur if pressure becomes excessive, safety devices fail, or the tank becomes badly damaged.

Warning signs may include water leaking from the pressure relief valve, extreme water temperatures, unusual sounds, tank movement, or visible tank damage.

Do not block or cap a pressure relief valve. Contact a professional if the valve is leaking, discharging often, or appears damaged.

Tank Water Heater Repair and Installation

Traditional water heaters store heated water inside a tank until it is needed. They are available in several sizes and may use natural gas, propane, electricity, or other energy sources.

Common Tank Water Heater Repairs

• Thermostat replacement
• Heating element replacement

Electric Water Heater Repair and Installation

Electric water heaters use one or more heating elements inside the tank. Common problems involve thermostats, heating elements, wiring, breakers, or safety controls.

Electric Water Heater Warning Signs

• No hot water
• Only a small amount of hot water
• Changing temperatures
• A tripped circuit breaker
• A burning smell
• Water leaking near electrical parts

Electrical testing and repair should be completed by a qualified professional. Water near energized equipment can create a serious safety risk.

Heat Pump Water Heater Services

Heat pump water heaters use electricity to move heat from the surrounding air into the water. They may use less electricity than standard resistance-style electric water heaters.

These systems generally need:

• Enough surrounding air space
• Proper electrical service
• Condensate drainage
• A suitable installation location
• Enough ceiling height

Heat pump systems may also cool and dehumidify the room where they are installed.

Water Heater Replacement

Not every water heater problem requires replacement. However, a new unit may be the better option when the existing system is old, leaking, badly corroded, or in need of frequent repairs.

Consider Replacement When:

• The tank itself is leaking.
• The unit has major corrosion.
• Repair costs are close to replacement costs.
• The water heater needs frequent service.
• The tank is too small for the property.
• Replacement parts are difficult to find.
• The system is no longer energy efficient.
• The property is being remodeled.

Repair May Be Reasonable When:

• The tank is not leaking.
• The system is still fairly new.
• The problem involves a valve or connection.
• A thermostat has failed.
• An electric heating element needs replacement.
• The repair cost is much lower than replacement.

Choosing the Right Water Heater Size

A water heater that is too small may run out of hot water during busy periods. A unit that is larger than needed may cost more to purchase and operate.

Factors Used to Size a Water Heater

• Number of people using hot water
• Number of bathrooms
• Shower and bath use
• Dishwasher use
• Washing machine use
• Large tubs or high-flow fixtures
• Whether several fixtures are used at once

For tankless systems, the plumber will also consider flow rate, incoming water temperature, and the number of fixtures that may run at the same time.

What Happens During Water Heater Installation?

1. The existing system is inspected.
   The plumber reviews the old unit, plumbing, energy source, venting, and installation area.
2. The old water heater is shut down.
   Water, gas, or electrical service is safely disconnected.
3. The old unit is drained and removed.
   Safe removal may require more than one person when the unit is large or difficult to reach.
4. The installation area is prepared.
   Valves, drain pans, venting, pipes, supports, or electrical connections may need to be updated.
5. The new system is installed.
   The water heater is connected to the water supply and energy source.
6. The system is filled and tested.
   The plumber checks for water, gas, exhaust, or electrical problems.
7. Operation is reviewed.
   The property owner should receive basic information about settings and maintenance.
