Signs Your Water Heater Needs Repair
Identifying a problem early can prevent further damage and more costly repairs down the line. Pay attention to these common indicators that your water heater may be in need of professional attention:
- Lack of Hot Water: This is often the most obvious sign. If your water isn't getting hot at all, or runs out much faster than usual, a component like the heating element, thermostat, or pilot light may have failed.
- Rusty or Discolored Water: If the hot water coming from your taps appears rusty or has a reddish tint, it could indicate corrosion inside the water heater tank. This is a serious sign that needs immediate inspection.
- Strange Noises: Popping, cracking, rumbling, or hissing sounds coming from the water heater tank can signal sediment buildup on the heating element or the bottom of the tank. As water heats, it interacts with this sediment, creating noise. Excessive noise can reduce efficiency and shorten the unit's lifespan.
- Leaking Water: Any water pooling around the base of your water heater is a clear sign of a leak. Leaks can come from various points, including connections, valves, or potentially a crack in the tank itself. Leaks should always be addressed quickly to prevent water damage.
- Low Hot Water Pressure: While low pressure throughout your home might be a separate issue, if only your hot water taps have reduced pressure, it could be due to sediment buildup restricting flow within the water heater or pipes leading from it.
- Inconsistent Water Temperature: If your hot water fluctuates between hot and cold during a single use, the thermostat might be faulty, or sediment could be interfering with the heating process.
- Foul Odors: A sulfur or "rotten egg" smell in your hot water is often caused by bacteria inside the tank, which can be treated.
- Age of the Unit: While not a direct sign of failure, if your conventional tank-style water heater is nearing or past its typical lifespan (often 10-12 years), it's more likely to experience problems and may warrant repair or replacement consideration.
Ignoring these signs can lead to decreased efficiency, higher energy bills, and ultimately, complete system failure. If you notice any of these issues, especially if your home is in Castle Hills, TX, it's time to consult a plumbing professional.

Common Water Heater Problems We Solve
Drawing on extensive experience with residential plumbing systems in the Castle Hills area, we're equipped to diagnose and repair a wide range of water heater issues affecting both traditional tank-style units and Tankless Water Heaters, powered by gas or electricity. Some of the frequent problems we address include:
- Faulty Heating Elements (Electric Units): When an electric water heater stops producing hot water, one or both heating elements are often the culprits. We test and replace defective elements.
- Pilot Light or Thermocouple Issues (Gas Units): A pilot light that won't stay lit or a malfunctioning thermocouple (safety sensor) can prevent a gas water heater from heating water.
- Thermostat Problems: Inaccurate or broken thermostats can lead to inconsistent temperatures or a complete lack of hot water.
- Leaking Connections or Valves: Leaks commonly occur at pipe connections, the temperature and pressure relief (T&P) valve, or the drain valve. We can identify the source of the leak and perform the necessary Pipe Leak Repairs.
- Tank Leaks: A leak directly from the tank itself is often a sign of irreparable corrosion and typically necessitates Water Heater Repair & Install.
- Sediment Buildup: Hard water can leave mineral deposits (sediment) at the bottom of tank-style heaters. This reduces efficiency, causes noise, and can damage the tank over time. Flushing the tank can remove sediment.
- Anode Rod Depletion: The anode rod protects the tank from corrosion by attracting corrosive elements in the water. A depleted anode rod leaves the tank vulnerable, leading to rust and leaks.
- Burner Issues (Gas Units): Problems with the gas burner can affect heating performance and efficiency.
- Pressure Issues: High water pressure entering the home can stress the water heater tank and components. Low pressure exiting the hot side can be due to clogs.
Our technicians are trained to handle these and many other water heater concerns, ensuring a thorough and effective repair.

Repair vs. Replace: Making the Right Choice
A common question homeowners face is whether to repair their existing water heater or opt for a full Water Heater Repair & Install or replacement. We help you navigate this decision by considering several key factors:
- Age of the Unit: A tank-style water heater over 10-12 years old is generally nearing the end of its lifespan. Repairs on older units may only offer a temporary fix before other components fail.
- Cost of Repair vs. New Unit: If the cost of the repair is significant (e.g., approaching 50% of the cost of a new unit), replacement is often the more economical long-term solution.
- Frequency of Issues: If your water heater requires frequent repairs, it might be a sign of systemic decline, making replacement a more reliable option.
- Energy Efficiency: Newer water heater models, including modern tankless systems like Tankless Water Heaters, are significantly more energy-efficient than older units. Replacing an old heater can lead to noticeable savings on energy bills over time.
- Type of Problem: Certain issues, like a leaking tank, are usually irreparable and require replacement.
Our technicians can provide an honest assessment of your unit's condition and recommend the most cost-effective and reliable path forward, whether it's repair or replacement. We can discuss options for both traditional and Conventional and Tankless Water Heaters Installation.

Frequently Asked Questions About Water Heater Repair

Should I call a plumber or an electrician for an electric water heater issue?
For almost all water heater problems, whether gas or electric, you should call a licensed plumber. Plumbers are trained to work with the plumbing aspects (tanks, pipes, valves) and the heating systems (including electrical elements and thermostats) of water heaters. While an electrician handles general electrical wiring in your home, water heater repair falls under the specialized expertise of a plumber.
How long do water heaters typically last?
The lifespan of a water heater depends on its type, maintenance, water quality, and usage. A conventional tank-style water heater typically lasts between 10 to 12 years. Tankless Water Heaters often have a longer lifespan, potentially 15-20 years or more with proper maintenance. Regular Water Heater Maintenance can help extend the life of your unit and catch potential problems early.
