Is A Leaking Hot Water Heater Dangerous?

Many homeowners are unaware of the dangers that a leaking water heater can bring. The most dangerous results from a leaking water heater are water damage, mold, and potential fires or explosions. 

Water Damage and Mold 

Water damage can affect both your home and the inhabitants who live inside. Prolonged water damage can stain walls and floors, weaken your home’s structure and foundation, corrode your pipes, and damage electrical systems. Moisture can also bring about unpleasant odors and allow mold, pests, and harmful fungi or bacteria to fester. The consequences of water damage can be very dangerous, as it can pave the way for floods, further breakage, and potential illness or injury.   

Mold thrives in moisture. You want to act fast if you find mold in your home. Mold can be detrimental to your health, particularly to those who are already sensitive to allergens in the environment or have pre-existing health conditions. By getting your leaking hot water heater fixed, and repairing the damage it left behind, you can avoid symptoms like: 

• Itchy or watery eyes 

• Itchy or red skin 
• Shortness of breath 
• Wheezing 
• Difficulty breathing 
• Upper respiratory infections 

• Development or exacerbation of asthma 
• Allergic reactions 
• Fever  

Potential Fires or Explosions 

Leaking is particularly more dangerous if you have an electric water heater. This is because water can spark an electrical fire. If any leaking water reaches the water heater’s electrical units, it can cause them to short circuit. In the most extreme cases, water heaters can explode. 

The average water heater packs the same amount of energy as 50 grams of TNT or a military MKII hand grenade. Making sure that your temperature and pressure relief valve is working properly and not leaking is extremely important. Not only does it control the temperature and pressure of the water inside your water heater, but it also protects you and your home. If the pressure inside a water heater builds up enough, there is a small chance that it can cause fire damage (as well as water damage) to your home.
