Water Heaters questions, answered by experts

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.

While possible, professional assistance is recommended to ensure compliance with local regulations and avoidance of avoidable risks.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

Yes, a water heater can be replaced in a day and can take between two and three hours to install from start to finish. Even if you encounter extra tasks that need to be completed, the job can still be completed in one day.
