What to Do If Your Water Heater Starts Leaking

Home | Blog | Published on July 21st, 2025

A leaking water heater is more than just an inconvenience—it can lead to major water damage, high utility bills, and a complete loss of hot water. At Creative Comfort Solutions, we know how stressful a water heater leak can be, especially when you’re unsure whether it can be fixed or if it’s time for a replacement. Here’s a step-by-step guide on what to do when you notice a leak, how to prevent further damage, and when to call in the pros for water heater repair.

Step 1: Shut Off Power or Gas Supply

The first thing you should do is turn off your water heater’s power source. For electric water heaters, shut off the power at your circuit breaker. If you have a gas water heater, locate the gas shut-off valve and turn it to the off position. This reduces the risk of electrical hazards or gas leaks while you assess the problem.

Step 2: Turn Off the Water Supply

Find the cold water shut-off valve at the top of your water heater and turn it clockwise to stop incoming water. If the valve is stuck or inaccessible, you may need to shut off the main water supply to your home.

Step 3: Identify the Source of the Leak

Once it’s safe, take a close look at the water heater to find out where the leak is coming from. Common leak sources include:

  • Cold or hot water inlet/outlet connections
  • Drain valve near the bottom of the tank
  • Temperature and pressure relief (T&P) valve
  • The tank itself due to internal corrosion

Minor issues like a loose valve or fitting can sometimes be repaired, but if the tank is leaking, replacement is usually the only option.

Step 4: Minimize Water Damage

If water has started to pool, grab towels, a wet/dry vacuum, or a mop to contain the damage. Set up fans or a dehumidifier to help dry the area. Leaks left unattended can cause mold growth and damage floors, drywall, and nearby appliances.

Step 5: Call Creative Comfort Solutions for Help

Once you’ve secured the area, it’s time to bring in the experts. At Creative Comfort Solutions, we provide fast, reliable water heater repair services and expert guidance on whether a repair or full replacement makes the most sense. Our skilled technicians will inspect your unit, fix any issues if possible, and recommend cost-effective options if your water heater has reached the end of its life.

Repair or Replace? Here’s How to Decide

In general:

  • Repair if: The leak is coming from a valve or connection, and your unit is less than 8 years old.
  • Replace if: The tank is leaking, the unit is 10+ years old, or repairs would cost more than half the price of a new heater.

Either way, you don’t have to decide alone—our team is here to help.
