Water Heater Leaking in Cary? Here’s What You Should Do First

If you’ve noticed water pooling around your water heater or dampness in your utility closet, you’re not alone. Homeowners across Cary, NC frequently experience water heater leaks, especially in older homes or during seasonal temperature changes. A leaking water heater may seem like a minor nuisance, but if left unchecked, it can quickly escalate into serious property damage, mold growth, or even complete system failure.

In this guide, we’ll walk you through exactly what to do the moment you spot a leak, when to call a professional, and how Cary homeowners can prevent future issues.

🔧 Step 1: Turn Off the Power Supply Immediately

Safety first. Your water heater either runs on electricity or natural gas, and when water is leaking around electrical components or burners, it can be dangerous.

• If Electric: Locate the circuit breaker panel in your home and turn off the breaker labeled “Water Heater”.
• If Gas: Turn the gas supply valve to the “off” position. This is typically located on the gas line going into the heater.

⚠️ Do not attempt to open panels or touch wires if there’s visible water on or around the unit.

💧 Step 2: Shut Off the Water Supply

Next, stop more water from entering the tank.

• Look for the cold water shut-off valve at the top of the water heater (usually a blue knob).
• Turn it clockwise to stop the water flow.

If this valve is stuck or inaccessible, shut off the main water supply to your home. In Cary homes, the main shut-off valve is often located in the garage, crawlspace, or where the water line enters the house.

🔍 Step 3: Identify the Source of the Leak

Once the area is safe and water flow is stopped, try to find where the leak is coming from. This can help determine the next steps — and whether the heater needs a simple repair or full replacement.

Common leak locations:

• Top of the tank: Usually due to loose inlet/outlet connections or valve issues.
• Bottom of the tank: Often signals internal corrosion or tank failure — likely needs replacement.
• Pressure relief valve (T&P valve): May release water if the temperature/pressure is too high.
• Drain valve: If this is dripping, it may be loose or faulty.

💡 Take a few photos of the leak area in case you need to show a technician later.

🧹 Step 4: Drain the Tank (Optional if Leak is Major)

If the tank is leaking heavily and you need to prevent further water damage:

1. Attach a garden hose to the drain valve near the bottom.
2. Run the hose to a nearby floor drain or outside.
3. Open the valve and let the water drain out.

Only do this if you’re comfortable with the process and have shut off both water and power.

🏡 Why Water Heaters Leak in Cary, NC

You might be wondering: why did my water heater start leaking in the first place?

Some common causes in Cary include:

• Aging Units: Most water heaters last 8–12 years. After that, tank corrosion and wear are common.
• Hard Water: Cary’s water supply contains moderate mineral content, which causes sediment buildup.
• Poor Installation: Faulty connections, improper pipe fittings, or lack of expansion tanks.
• Thermal Expansion: If your home doesn’t have a pressure expansion tank, hot water expansion can stress valves and cause leaks.

---

🛠️ Prevent Future Leaks with These Tips

• Flush your tank once per year to remove sediment.
• Install a leak detection alarm near your unit.
• Check your anode rod every 3–4 years to prevent rust inside the tank.
• Schedule annual water heater inspections with a licensed plumber.
