A functioning water heater is essential for your daily comfort. Whether you’re relying on a traditional tank water heater or a modern tankless model, keeping it in good working condition is crucial. Ignoring signs of trouble can lead to costly repairs—or worse, total system failure. At Miller and Sons Plumbing, we’re here to help you recognize the warning signs and act before a minor issue becomes a major headache.
1. Fluctuating Water Temperature
If your water temperature shifts unpredictably from hot to cold, it’s a clear indicator that something is wrong. For tank water heaters, sediment buildup at the bottom of the tank may reduce its heating efficiency. In tankless models, mineral deposits can clog the unit, impacting its ability to heat water consistently.
What to Do: If this issue persists, don’t wait. A professional inspection can pinpoint the problem and prevent further damage.
2. Unusual Noises
Hearing banging, popping, or rumbling noises coming from your water heater? For tank models, this could be a sign of sediment buildup being reheated, which strains the system. Tankless units might make odd noises if there’s scale accumulation or a malfunctioning part.
What to Do: Regular flushing of the unit can address sediment or scale issues, but if the noises persist, it’s time to call in the pros.
3. Leaks or Puddles Around the Unit
Leaking water is a clear sign of trouble. For tank water heaters, it could mean the tank is corroded or a valve is loose. Tankless units may leak if there’s an issue with the water supply or internal components.
What to Do: Even a small leak can quickly escalate, so don’t delay. Shut off the water supply and call us immediately for repairs.
4. Inconsistent Water Pressure
Weak or fluctuating water pressure could indicate a problem with the water heater’s connections or internal systems. Mineral buildup or pipe blockages are common culprits in both tank and tankless systems.
What to Do: A licensed plumber can assess the situation and restore your water pressure to normal levels.
5. Higher Energy Bills
A sudden spike in your energy bills might point to an inefficient water heater. Tank heaters with sediment buildup require more energy to heat water, while tankless units may be overworking due to clogged filters or other issues.
What to Do: Routine maintenance, such as flushing and descaling, can improve efficiency. If the problem persists, it may be time for repairs—or even a replacement.
6. Discolored or Smelly Water
If your hot water appears rusty or has a foul odor, your tank water heater’s anode rod may have corroded, or the tank itself might be deteriorating. In tankless units, bacteria or mineral buildup could be the cause.
What to Do: Addressing this issue promptly is essential to avoid health risks and further system damage.
Why Routine Maintenance Matters
Whether you have a tank or tankless water heater, routine maintenance is your best defense against costly repairs. Annual flushing, descaling, and professional inspections can extend the life of your system and keep it running efficiently.
