Water heaters are essential appliances in most homes, providing hot water for showers, laundry, and other daily tasks. However, corrosion, sediment buildup, pressure fluctuations, and other factors can lead to a water heater leak.
A leaky water heater can pose serious risks to your property and safety. In this blog post, we will explore the dangers of leaky water heaters and provide tips on how to address a water heater leak.
It is important to note that in most cases, a leak isn’t dangerous; it’s just an inconvenience. However, in some cases, a leak does pose a hazard. You should contact an experienced plumbing technician as soon as possible, as it is in your best interest.
A Leaky Water Heater Can Be a Threat to You & Your Property
You should address a leaky water heater as soon as possible for the following reasons:
- Carbon monoxide poisoning. Gas water heaters can leak carbon monoxide, a colorless and odorless gas that can be fatal.
- Electrical hazards. If a leaky water heater comes into contact with electrical components, it can cause a short circuit or even a fire.
- Flooding. If you use your water heater while you have a leak, you run the risk of making the leak worse and causing flooding. The water pressure in the tank increases, which can make the leak larger.
- Gas leak. In some cases, your gas system can also be affected by a water leak, which can lead to a gas leak.
- Increased energy costs. A leaky water heater may require more energy to heat water, leading to higher utility bills.
- Mold growth. Excess moisture can create a breeding ground for mold, which can trigger allergies, respiratory problems, and other health concerns.
- Scalding water. If your leak is related to a broken component like a malfunctioning T&P valve, that can mean the heater’s thermostat or temperature detector also malfunction. This can lead to you being burned while showering or using the water.
- Tank explosion. This outcome is very rare. However, in some cases, your water heater tank may explode because of a pressure buildup.
- Water damage. Leaks can cause extensive property damage, including ruined floors, walls, and furniture. Water can also seep into your home's foundation, leading to structural issues.
Is It Okay to Shower When the Water Heater Is Leaking?
No. You should avoid using your water at all. Showering while you have a leaking water heater can lead to:
- Increased water damage.
- More of a safety hazard.
- A worsened leak.
You should only continue to use hot water on a temporary basis. The sooner you address the leak the better.
What to Do If You Have a Leaky Water Heater
Below, we offer a step-by-step guide on how to respond to a leaky water heater:
- Turn off the water supply. Locate the shut-off valves to your water heater and turn them off completely. This will prevent the leak from worsening and reduce the risk of water damage.
- Turn off the electrical power. If your water heater is electric, turn off the breaker that supplies power to it. This will help prevent electrical hazards.
- Contact a professional. Call a licensed plumber to assess the damage and repair the leak. They have the expertise to handle the situation safely and efficiently.
- Drain the water heater. Once the water supply and power are off, drain the remaining water from the heater. This will help prevent further damage and make it easier for the plumber to work.
- Inspect for damage. Look for signs of water damage throughout your home, such as wet spots on the ceiling or floor, or musty odors. If you find any damage, take steps to address it promptly.
When following these steps, you can minimize the impact of a leaky water heater and prevent further problems.
