- Leave the building immediately.
- Do not use lights, switches, appliances, or phones inside.

Common gas water heater repairs include:
- Pilot light problems

Common Water Heater Problems
Why is my water heater not producing hot water?
Possible causes include a failed heating element, thermostat, pilot assembly, burner, gas control valve, electrical connection, or tankless ignition component. Testing is required to identify the failed part.
Why does my hot water run out quickly?
Reduced hot water capacity may result from sediment buildup, a failing heating element, a damaged dip tube, an undersized unit, or a malfunctioning thermostat. Tankless systems may have scale or flow-related issues.
Why is my water heater leaking?
Leaks may come from supply connections, fittings, drain valves, temperature and pressure relief valves, or the tank itself. A leaking tank usually requires replacement.
Why does my water heater make popping or rumbling noises?
Popping and rumbling sounds often indicate sediment buildup inside a tank. Sediment can reduce efficiency and damage heating components. Flushing may help when the tank remains structurally sound.
Why is my hot water rusty?
Rust-colored water may indicate a deteriorated anode rod, corrosion inside the tank, or aging plumbing connections. A professional inspection can locate the source.
Why does my water heater keep tripping the breaker?
A failed heating element, thermostat, damaged wiring, overloaded circuit, or electrical fault may be responsible. Stop resetting the breaker and schedule an inspection.
