Why Should You Care About a Leaking Water Heater?

Even a small leak can have big consequences. While you might be tempted to ignore a minor drip from your water heater, it’s important to understand that even a small leak can lead to significant damage.

Water Damage: Even a small leak can cause water damage to your floors, walls, and ceilings. Over time, this damage can lead to mold growth, structural issues, and costly repairs.
Electrical Hazards: If water leaks near electrical components, it can create a dangerous situation. Electrical shocks and fires can occur if water comes into contact with electrical outlets or wiring.
Increased Energy Costs: A leaky water heater can cause your energy bills to skyrocket. Water leaks can reduce the efficiency of your water heater, forcing it to work harder to maintain hot water.
Health Concerns: Mold growth caused by water leaks can pose serious health risks, especially for individuals with allergies or respiratory problems.

Why is my water heater leaking? (Is it supposed to drip?)

It’s important to distinguish between a normal drip and a leak. If you’ve got a water heater leaking from top side, it could indicate a problem with the pressure relief valve or the inlet connections. If it’s a hot water heater leaking from bottom, it might be a sign of a more serious issue, such as a cracked tank.

Understanding Water Heater Basics

Before we dive into troubleshooting your leaky water heater, it’s important to have a basic understanding of how water heaters work. There are two main types of water heaters: tankless and tank.

Tankless Water Heaters:

How they work: Tankless water heaters heat water on demand, providing hot water as needed. They are typically more energy-efficient than traditional tank heaters.
Can they leak? Yes, tankless water heaters can leak. Common causes of leaks include faulty connections, corrosion, and sediment buildup.

Tank Water Heaters:

How they work: Tank water heaters store a large amount of hot water in a tank. When you turn on a hot water faucet, the hot water is drawn from the tank.
Can they leak? Yes, tank water heaters can leak. Common causes of leaks include a faulty pressure relief valve, corrosion, or a cracked tank.

Understanding the type of water heater you have will help you identify the potential causes of your leak and determine the best course of action.

Common Reasons for Water Heater Leaks and Solutions

1. Faulty Pressure Relief Valve:

Why it leaks: The pressure relief valve is a safety device that releases excess pressure to prevent the tank from exploding. If it’s faulty or clogged, it can leak.
Solution: Replace the faulty valve.

2. Corrosion:

Why it leaks: Over time, the tank of your water heater can corrode, leading to leaks.
Solution: If the corrosion is minor, you may be able to repair it. However, if the corrosion is extensive, you may need to replace the entire water heater.

3. Sediment Buildup:

Why it leaks: Sediment buildup can cause the tank to corrode and eventually leak.
Solution: Flush your water heater regularly to remove sediment buildup.

4. Leaky Fittings or Connections:

Why it leaks: Loose or corroded fittings and connections can cause leaks.
Solution: Tighten or replace any faulty fittings or connections.

5. Cracked or Damaged Tank:

Why it leaks: A cracked or damaged tank is often the most serious cause of a water heater leak.
Solution: If the tank is damaged, you will need to replace the entire water heater.

6. Anode Rod Failure:

Why it leaks: The anode rod is a sacrificial metal that helps prevent corrosion. If it fails, the tank can corrode and leak.
Solution: Replace the anode rod.

7. Temperature and Pressure Settings:

Why it leaks: Incorrect temperature and pressure settings can put stress on the water heater and cause leaks.
Solution: Ensure that your water heater is set to the recommended temperature and pressure.

Next Steps: Addressing Your Water Heater Leak

1. Shut Off the Water Supply:

Locate the main shut-off valve and turn it off to prevent further water damage.
If you have a tank water heater, also shut off the cold water supply to the heater.

2. Drain the Water Heater (if necessary):

If the leak is significant, you may need to drain the water heater to prevent further damage.
Refer to your owner’s manual for instructions on how to drain your specific model.

3. Identify the Source of the Leak:

Carefully inspect the water heater for signs of leaks, such as water dripping from the bottom, sides, or top.
Look for signs of corrosion, rust, or damaged fittings.

4. Attempt Repairs (if possible):

If the leak is minor and you have some plumbing experience, you may be able to make repairs yourself. However, it’s important to consult with a professional if you’re unsure.
Common repairs include replacing a faulty pressure relief valve, tightening loose fittings, or flushing the water heater to remove sediment.

5. Call a Professional Plumber:

If you’re unable to identify or fix the leak yourself, it’s important to call the professionals at AC Pros. They have the experience and tools to diagnose and repair water heater leaks efficiently.

6. Consider Replacing the Water Heater:

If the leak is caused by a major issue, such as a cracked tank, you may need to replace the entire water heater.
A professional plumber can assess the damage and provide you with a quote for a replacement.

Remember: Safety is paramount when dealing with a water heater leak. If you’re unsure about any of the steps involved, it’s best to consult with a professional plumber.

Water Heater Leak – Is It Fixable or Should I Replace It?

Whether your water heater leak is fixable or requires replacement depends on the severity of the damage. Here are some common scenarios:

Minor leaks: If the leak is small and caused by a faulty pressure relief valve, loose fittings, or sediment buildup, it may be possible to repair the issue. A professional plumber can assess the damage and recommend the appropriate course of action.
Major leaks: If the leak is caused by a cracked tank, extensive corrosion, or other significant damage, it is typically more cost-effective and safer to replace the entire water heater.

Factors to consider when deciding whether to repair or replace:

Age of the water heater: If your water heater is nearing the end of its lifespan (usually around 8-12 years), it may be more cost-effective to replace it rather than invest in repairs.
Cost of repairs: Consider the cost of repairs compared to the cost of a new water heater. If the repairs are extensive or expensive, it may be more economical to replace the unit.
Safety concerns: If the leak poses a safety hazard, such as being near electrical components or causing water damage, it is important to address the issue promptly.

Ultimately, the decision of whether to repair or replace your water heater should be based on a comprehensive assessment of the damage, the age of the unit, and your budget. We offer consultations to provide you with advice and guidance for your specific situation.
