Why is my Water Heater Leaking and how can it be Fixed?

In Calgary, water heater leaks are often caused by the citys specific environmental factors. The high levels of calcium and magnesium in local hard water accelerate corrosion of the tank and its pipes, while extreme winter temperatures below -30C put additional thermal stress on the system. Puddles under the unit or dripping fittings are signs of urgency to prevent flooding.

To address and fix a leaking water heater, you should follow these steps:

1. Safety First: Immediately turn off the power or gas supply to the unit and wear protective gear before performing any checks.
2. Inspect the Source: Check the base of the tank and the connecting pipes. Mineral buildup from the hard water supply is a common culprit for corrosion at these points.
3. Flush the Tank: Perform a sediment flush by connecting a hose to the drain valve and running it for 10 to 15 minutes until the water runs clear. This helps mitigate issues caused by sediment buildup.
4. Professional Repair: Because leaks are considered a safety hazard, they often require certified technicians. For tankless systems, repairs must also comply with Natural Resources Canada federal regulatory standards. Professional intervention ensures that the unit is fixed correctly without voiding manufacturer warranties.
