Is a Leaking Water Heater Dangerous?

A leaking water heater is not just an inconvenience but can pose a significant danger to your property and your family. It carries its own unique set of risks. For instance, water leaking from the temperature and pressure (T&P) valve indicates unsafe pressure and temperatures in the heater, potentially leading to an explosion.

The danger of a hot water heater leaking depends on the root cause of the leak. Even a small leak may cause substantial damage. Even if a leaking hot water heater isn’t a dangerous situation initially, it could cause substantial water damage if not addressed promptly.

Regardless of what causes the leak, it’s important to get it fixed as soon as possible.

Why Is My Water Heater Leaking?

Water heaters can leak for several reasons, and understanding these causes is crucial for effective maintenance and problem-solving. Common reasons include:

  • Pressure valve malfunction
  • Tank issue (corrosion and rust)
  • Plumbing connections
  • Worn out seals
  • Excessive pressure

Pressure Valve Malfunction

The pressure relief valve relieves excess pressure inside the tank to prevent an explosion. If this valve malfunctions, it can cause the water heater to leak. This leak can lead to severe water damage and potential flooding. Regular maintenance can prevent such issues. If not caught in time, a malfunctioning pressure relief valve could mean costly repairs or even a complete replacement of the system.

Tank Issue (Corrosion and Rust)water heater leaking

Rust and corrosion are common issues in water tanks that can lead to leaks. Over time, rust buildup can cause internal corrosion, which creates cracks in the tank. This process, known as oxidation, weakens the tank material and can eventually lead to tank failure. Regular inspection and maintenance are essential in preventing these issues and ensuring the longevity of the water tank.

Plumbing Connections

Plumbing connections are integral to an efficient water system. However, they can also be a source of leaks. Tightening the inlet and outlet connections could solve the problem if they’re loose. 

Worn Out Seals

Worn-out seals, particularly around the heating elements, can cause water to leak from the water heater. Gaskets can become loose or damaged over time. It’s important to check and replace these seals to prevent leakage periodically. Failure to do so can cause inefficient heating and potential water damage in the long term.

Excessive Pressure

Excessive pressure within the water heater can cause leaks, too. If the water pressure in your tank becomes excessive, it can cause water to escape. This excess pressure occurs when the temperature setting on the water heater is set too high. That’s why maintaining an optimal temperature setting is crucial to prevent over-pressurization. A pressure relief valve can also be installed as a safety measure to control pressure levels.

How to Stop Water Heater Leak

When a water heater leak is detected, acting swiftly to minimize damage and ensure safety is important. Here are some steps to follow in the event of a water heater leak.

Shut off the Power Supply to the Water Heater

First, make sure to disconnect the power supply from the water heater. If you own an electric heater, turn off the breaker in your panel. For gas heaters, switch the thermostat to the ‘off’ position.

Identify the Reason for the Leak

Once the power is turned off, determine what’s causing the leak. We’ve discussed some reasons, such as a faulty pressure valve, rust or corrosion in the tank, problems with plumbing connections, worn-out seals, or excessive pressure within the system.

Mitigate the Damage

Next, it’s time to mitigate the damage. Placing a bucket underneath the leak can help contain the water and prevent further damage to your floors or walls. Shut off the water supply to the heater. Most water heaters have an easily accessible shutoff valve on the cold inlet pipes.

Call a Professional Technician

Finally, call a professional technician. Water heater repairs can be complex, even dangerous, if not handled properly. A professional plumber can accurately diagnose the problem and provide a safe and effective solution. 

Even if you’ve managed to stop the leak temporarily, getting a professional assessment is still recommended to lower the chances of future leaks and ensure the longevity of your water heater. Contact the contractors at Hurley & David for emergency services. Schedule an installation today.

Do You Need a Water Heater Repair or a Replacement?

Deciding to repair or replace a water heater can be a difficult choice to make. Factors like the heater’s age, the expenses involved in repairs, and the overall condition of the unit will all play a role in making this decision.

One used guideline is known as the 50% rule, which advises that if the cost of repairs amounts to 50% or more of what it would cost to replace the unit, it’s probably more cost-effective to opt for a replacement. Another guideline suggests replacing the water heater if the repairs exceed $500 and the unit is over eight years old.

The lifespan of your water heater can also help you decide what measures to take. If your traditional water heater is over 10 years old, consider getting a new unit. The average tank water heater can last between six to 12 years with proper care and maintenance. If you notice any leaks coming from the tank itself, getting a replacement is usually recommended. Leaks can cause damage and pose potential safety hazards. Once you start experiencing leaks, the chances of you experiencing more only increase.

Regardless of whether you decide to repair or replace your water heater, you should always seek assistance. Water heater services often involve more than replacing a single component and should be handled by an experienced plumber.

Why Is My Water Heater Leaking?

A leaking water heater is not just a nuisance but can also pose significant dangers, from causing extensive water damage to posing an explosion risk. When faced with a leaking water heater, assess whether a repair or replacement is the most appropriate solution. Consider factors like the unit’s age, the cost of repairs, and the overall condition of the heater.
