Water Heater Repair FAQs

What are the signs my water heater needs repair?

Several signs indicate your water heater needs attention:

• Lack of hot water: If you have little or no hot water, it points to a problem.
• Leaking water heater: Water leaking from the tank or pipes is a serious issue requiring immediate action.
• Strange noises: Unusual sounds like banging, popping, or rumbling suggest potential issues.
• Temperature inconsistencies: The water temperature fluctuates excessively.
• Rusty or discolored water: Rusty water suggests corrosion inside the tank.
• Increased energy bills: A water heater working harder than usual can impact energy consumption.
• Age of the water heater: Most water heaters last 8-12 years. Older units are more prone to failure.
• Frequent cycling: The water heater turns on and off more often than usual, possibly indicating a problem with the thermostat.

If you experience any of these problems, contact a qualified plumber to diagnose and address the issue before it becomes a larger, more expensive problem.

How often should I flush my water heater?

Flushing a tank water heater removes sediment buildup, improving efficiency and extending its lifespan. The recommended frequency is annually, but it may depend on water quality and usage.

What causes a water heater to leak?

Water heater leaks can stem from various issues:

• Corrosion: Over time, the tank can corrode, especially at the bottom, leading to leaks.
• Cracked tank: A crack in the tank, usually due to pressure or temperature fluctuations, results in leaks.
• Faulty drain valve: A damaged drain valve can leak water.
• Loose or damaged pipes: Leaks can occur at connections between the tank and pipes.
• Pressure relief valve issues: A malfunctioning pressure relief valve may leak.
• Anode rod failure: The anode rod protects against corrosion; failure can lead to leaks.

A leak is a serious problem. Contact a plumber immediately.

What is a gas water heater pilot light?

A gas water heater typically has a pilot light, a small, constantly burning flame that ignites the main burner when the water heater is turned on. This pilot light is a safety feature of gas water heaters, but if it malfunctions, it can result in the water heater failing to heat water. A qualified plumber should address any pilot light issues.
