Why Water Heater Problems Are So Common in Orange, CA

Hard water conditions in Orange County contribute to many water heater failures. Minerals like calcium and magnesium collect inside tanks and on heating elements, leading to efficiency loss and eventual damage. Without regular maintenance, even high-quality water heaters can face shortened lifespans.

Common Water Heater Issues in Local Homes

1. No Hot Water at All

One of the most frequent problems homeowners report is a complete lack of hot water. Causes may include:

• Burned-out heating elements (electric units)
  
• Faulty gas burners or pilot lights (gas units)
  
• Broken thermostats or wiring issues
  
  

Pro tip: If your water heater is more than 10 years old, replacement may be more cost-effective than repeated repairs.

2. Water Temperature Fluctuations

If your water suddenly runs hot and cold, it may be due to:

• A failing thermostat
  
• Sediment buildup is restricting heat transfer
  
• Improperly sized water heater for your household demand

3. Leaking Water Heater Tank

Leaks are a serious issue that can cause property damage. Common leak sources include:

• Corroded tank walls
  
• Loose or broken fittings
  
• Faulty pressure relief valves
  
  

If you spot puddles near your water heater, call a licensed plumber immediately.

4. Strange Noises (Popping or Rumbling)

Mineral deposits settling at the bottom of your tank often cause popping or rumbling sounds. Over time, sediment makes your unit work harder, reducing energy efficiency. A professional water heater flush can often solve this issue.

5. Rusty or Discolored Water

Orange or brown water usually points to corrosion inside the tank or pipes. If your water has a metallic taste or smell, you may need water heater replacement.

6. Low Hot Water Pressure

Mineral buildup inside pipes and tank components often reduces water flow. Addressing this issue may require descaling, pipe inspection, or replacing outdated plumbing.
