Do you see water pooling around your unit? In most Pasadena homes, three culprits usually cause leaks: a loose drain valve, internal tank corrosion, or excessive water pressure.
Some leaks are minor inconveniences, but others warn of a looming tank burst. To prevent expensive water damage, shut off the water supply immediately and inspect the unit.
4 Common Reasons for Water Heater Leaks
Water heaters work hard, but local water conditions and age eventually degrade them. Here is what typically causes leaks in the San Gabriel Valley:
- The Drain Valve is Loose: This is the best-case scenario. The spigot at the bottom of the tank often rattles loose during operation. A simple wrench turn usually stops the drip.
- Sediment & Corrosion: Pasadena has moderately hard water. Minerals settle at the tank’s bottom and eat away the glass lining until the steel rusts and cracks.
- High Water Pressure: If your home’s water pressure spikes, or the relief valve fails, the tank may leak to release internal stress.
- Unit Age: Most tank-style heaters last 8 to 12 years. If yours exceeds this age, a leak usually confirms the tank has reached the end of its life.
When to Call a Pasadena Professional
If tightening the fittings fails, or if water weeps from the tank body, you need professional help immediately. You cannot safely patch a cracked tank; you must replace it to avoid flooding your home.
