Water heaters perform an essential function in our home, providing hot water for showers, cleaning, and other daily activities. However, they can also pose safety risks if not properly maintained. At Mister Water Heater, we’ve been asked if water heaters can explode and what to look for in our Indianapolis homes to prevent it from happening. Here are the top three signs that your water heater will need repair sooner rather than later.

Mister Water Heater Indianapolis Water Heater Safety

1. Rotten Egg Smell

A rotten egg smell around your gas water heater could equal a gas leak. Gas leaks are serious and can lead to explosions if not addressed promptly. If you notice this odor, evacuate the area immediately, call 911, and contact Mister Water Heater to inspect your unit.

2. Issues With the Temperature and Pressure Relief (T&P) Valve

The T&P valve is a critical safety component that releases excess pressure and temperature from the water heater. If it’s constantly open or if it’s leaking, it may indicate that there’s excessive pressure in the tank. This situation needs immediate attention from our professional repair service.

3. Rumbling or Banging Noises

Unusual noises like rumbling or banging are often due to sediment buildup at the bottom of the tank. This buildup can cause overheating and damage the tank, increasing the risk of an explosion.

Preventive Maintenance Tips

There are some practical steps you can take to prevent your water heater from overheating or exploding.

  • Regular Inspections: Hire a plumber from Mister Water Heater to do routine inspections so you can catch potential issues early on.

  • Annual Tank Draining: Draining the tank at least once a year helps remove sediment, improving efficiency and reducing the risk of overheating.

  • Check and Replace the T&P Valve: Regularly check the T&P valve for leaks or signs of malfunction. Then, contact one of our trusted plumbers to replace it so your water heater can maintain the right pressure release.
