Below, we discuss some causes for leaky water heaters.
Water Heater Age and Corrosion
Over time, water heaters can undergo natural wear and tear that leads to deterioration and leaks. The primary culprit is often corrosion inside the tank, which is inevitable as the protective lining wears away. Older units, typically those over 10-15 years, are more susceptible to such issues due to prolonged exposure to water minerals and oxygen.
Faulty or Loose Connections
Leakage can also occur at the water heater’s connections, where pipes meet the tank. If these fittings are improperly installed, become loose, or wear out, water can start to seep through. Regular maintenance is crucial to ensure all connections are tight and secure to prevent any water escape.
High Water Pressure
Excessive water pressure can strain your water heater as well as the plumbing throughout your home. Most tanks are designed to handle a specific range of pressure, and when the pressure exceeds these limits, it can cause the tank to leak or even burst. Installing a pressure-reducing valve can help manage and maintain safe pressure levels.

Hot Water Heater Temperature and Pressure Relief Valve Issues
The temperature and pressure relief valve (TPR valve) acts as a safety device that opens to release water if the pressure or temperature inside the tank gets too high. If this valve is faulty or clogged, it might not operate correctly, leading to leakage. Regular inspections can ensure the valve functions properly and safely.
Inadequate Water Heater Maintenance
Neglecting routine maintenance is a leading factor in premature water heater failures and leaks. Sediment buildup, rust formation, and general deterioration can all be mitigated with regular checks and maintenance, extending the lifespan of your unit and preventing unexpected leaks.

What Factors Require A Water Heater Replacement?
A homeowner is going to want a quick repair when a water heater leak is discovered because the longer the situation continues, the more damage and expense is incurred. One thing everyone seems to agree upon is that a water heater leak cannot be ignored.
As noted above, the causes of a water heater leak vary, some of which include such as the age of the hot water tank, the pressure of the water coming into the tank, a valve that is no longer functioning correctly, a crack in the tank or even sediment that has collected in the system over the years.
For some of these issues, a parts replacement may be the answer. However, for others, a tank replacement is a far better choice. An experienced and licensed plumber can quickly determine which is a more suitable option.

Repairing Vs. Replacing Your Leaking Hot Water Heater
It can be difficult for a homeowner to make that call – do I repair the tank that I have or should I invest in a new one? The best way to do this is to call in the professionals who can quickly determine the cause of the leak and the best way to ensure that it is fixed and does not begin to leak again soon.
Some factors to consider are how long the tank has been leaking, the age of the tank, and whether or not this repair is going to lead to more costly repairs rather than a long-term solution. Issues like age and location of the leak will help a plumber determine the most cost-effective way to move forward.
How Old is Your Water Heater?
While some systems last from 10 to 12 years and tankless heaters can even work for 20 years or more, it is not often a surprise when a system begins to show signs of wear, or even fail completely, 5 or 6 years after installation. Due to lack of maintenance, sediment can build up quickly in some systems and cause problems.
The Location of the Water Heater Leak
If you discover leaking around the bottom of the tank, the issue is likely from a drain valve or corrosion from mineral or sediment build-up. When the leak occurs toward the top of the tank, a faulty valve or failing joint may be the culprit. Any of these issues can be quickly diagnosed and addressed by a knowledgeable plumber.

Is it Even a Hot Water Heater Leak or Just Condensation?
A homeowner may discover what they believe is a leak, but is actually just condensation forming due to internal water temperature. A professional can inspect the tank thoroughly and may find that a costly repair is not even needed.
Suppose the water outside the tank is from a leak. In that case, the plumbing professional will determine if the leak can be repaired with a replacement part, like a gasket or pressure relief valve, or if the problem is more serious. A tank replacement may be a better solution for the long-term.
When A Water Heater Repair Isn’t An Option
If the tank itself is the problem and is leaking, rather than just a valve, pipe, or gasket, it is time to install a new hot water tank to provide efficient and reliable service. A leaking tank cannot be adequately repaired. A plumbing expert can let you know when replacement is the only option and can determine the best way to work within your budget to ensure that you get a new system that will meet all of your hot water needs.

Leaky Water Heater FAQs
What Should You Do Immediately Upon Discovering A Water Heater Leak?
If you notice your water heater leaking, the first step is to turn off the power supply to the unit to prevent any electrical hazards. For gas water heaters, you should also turn off the gas valve. Shutting off the water supply to the tank can help minimize further water damage. Once everything is safely disconnected, contact a professional plumber for an assessment.
Can A Water Heater Leak Be Temporary Or Self-Resolving?
While some homeowners might notice water that appears to be a leak, it could actually be condensation, especially during colder months. However, genuine leaks do not resolve on their own and require professional intervention to diagnose and fix the underlying issues effectively.
How Can You Identify The Source Of A Water Heater Leak?
To pinpoint where the leak is coming from, you can perform a basic inspection of the water heater. Check common sources like the TPR valve, drain valve, and water supply connections. Sometimes, the source of the leak may not be visible, indicating a potential crack or hole in the tank itself, necessitating a professional examination.

What Maintenance Can Prevent Future Water Heater Leaks?
Regular maintenance is key to extending the life of your water heater and preventing leaks. This includes annually draining the tank to remove sediment buildup, checking the anode rod for corrosion, inspecting the TPR valve for proper operation, and ensuring all connections and fittings are secure.
Is It More Cost-Effective To Repair Or Replace A Leaking Water Heater?
The decision to repair or replace a leaking water heater depends on several factors, such as the age of the unit, the location and severity of the leak, and the potential for future issues. Generally, if the water heater is near the end of its typical lifespan (around 10 years or more), replacing it might be more economically sensible considering the efficiency and reliability of newer models.

Conclusion
A water heater leak does not always spell out disaster. While your first thought may be that the system is going to need a costly replacement that may not actually be the case. A leak in a tank that is less than ten years old is often the result of a more minor issue in one of the parts that make up the system rather than in the tank itself. An expert can often repair it inexpensively.
However, particularly in older systems, the leak may mean that a water heater replacement is needed. In this case, an experienced plumber can inspect the entire system, recommend a brand and style of tank, or even a tankless system upgrade, that will better meet your household needs. A replacement tank can improve your water pressure, lower your monthly utility bills, and give you the peace of mind that comes from having a professional system installed by someone with the expertise to ensure that it is done correctly.
There are some minor issues that a homeowner can attend to when it comes to a home’s plumbing, but for larger, potentially dangerous problems like a leak in the hot water heating tank, it is always wise to get the advice of an expert who can inspect the tank and the entire system quickly and knows exactly how to proceed to keep your home’s water system safe and functioning as it should.
