A water heater is one of the most important appliances in your home, yet it often goes unnoticed because it’s usually tucked away in a utility room or basement. As a homeowner, it’s important to check your water heater regularly to make sure it’s operating properly and showing no signs of leaks. Even a small leak can quickly turn into a major plumbing issue if ignored.
If you do notice water around your water heater, there are a few common reasons why this might be happening. The most frequent causes are a faulty pressure relief valve or a crack in the water heater tank itself.
Leaking Pressure Relief Valve
The pressure relief valve is a critical safety component of your water heater. It releases excess pressure from inside the tank to prevent damage or failure. If this valve starts leaking, it’s often because it is not seated properly or has become clogged with sediment and mineral buildup over time.
In some cases, you may be able to fix the issue by carefully reseating the valve or cleaning it using a vinegar solution to remove sediment. However, if the valve continues to leak, it will need to be replaced. Replacing a pressure relief valve can be tricky, as it involves working with pressurized water and heat. Because of this, it’s always recommended to hire a professional plumber to ensure the job is done safely and correctly.
Cracked Water Heater Tank
A crack in the water heater tank is a much more serious issue. If you see water pooling around the base of the unit, it’s often a sign that the tank itself has cracked. Unfortunately, this is not something that can be repaired. Once a tank is cracked, the only real solution is to replace the entire water heater.
Cracks can form for several reasons, but one of the most common causes is expansion due to freezing temperatures. This is especially common in cottages, garages, basements, or older home additions where insulation may be inadequate. Even in areas where freezing isn’t common, aging tanks can weaken over time and eventually fail.
When to Call a Professional Plumber
If you’re not sure what’s causing your water heater to leak, the safest option is to call a licensed plumber. A professional can quickly inspect the unit, identify the source of the leak, and recommend the best solution—whether that’s a valve replacement, repair, or full water heater replacement.
