A leaking water heater is one of the most common plumbing emergencies homeowners face. Whether it’s a small drip or a major tank leak, ignoring the issue can lead to water damage, mold growth, and higher utility bills. In this guide, we break down the causes, repair options, and water heater repair vs replacement costs in Vancouver.
Common Reasons Your Water Heater Is Leaking
- Loose or faulty drain valve – often fixable with a simple repair

- Worn-out heating elements or fittings
- Condensation buildup (minor and often harmless)
