Water Heater Leaking? Do These 5 Things Immediately!

Problem: You walk into your basement or utility room and notice water pooling around your water heater. Panic sets in—what now? A leaking water heater can cause water damage, increase your utility bills, and even become a safety hazard if not addressed quickly.

Agitation: Ignoring a leak could lead to major problems, from mold growth to structural damage. If the leak is severe, it might even indicate a risk of tank failure, which can cause significant flooding. Knowing what to do immediately can save you from costly repairs and unnecessary stress.

Solution: Follow these steps to take control of the situation and prevent further damage.

1. Turn Off the Power Supply

• Gas Water Heater: Locate the gas shut-off valve and turn it to the "off" position.
• Electric Water Heater: Find your home's circuit breaker and switch off the power to the water heater to prevent electrical hazards.

2. Shut Off the Water Supply

• Find the cold water inlet valve (usually located at the top of the heater) and turn it clockwise to stop the water flow.
• If you can't find it or it's stuck, shut off your home’s main water supply.

3. Determine the Source of the Leak

• Top of the Tank: Likely a loose inlet or outlet pipe connection—tighten the fittings.
• Bottom of the Tank: Could be condensation, a faulty drain valve, or a failing tank.
• Side of the Tank: A leaking pressure relief valve may indicate excessive pressure inside the tank.

4. Drain the Tank If Necessary

• Attach a garden hose to the drain valve at the bottom of the tank.
• Run the hose outside or into a floor drain and open the valve to release water.
• Be cautious—hot water can cause burns.

5. Call a Professional Plumber

• If the leak is coming from the tank itself, it likely needs replacement.
• A plumber can determine if repairs are possible or if you need a new unit.
• For emergency situations, act quickly to minimize water damage.

Preventing Future Leaks

• Flush the tank annually to remove sediment buildup.
• Inspect the anode rod regularly—it helps prevent rust inside the tank.
• Check for signs of corrosion, especially if your water heater is over 8-10 years old.
