Common Water Issue in BC

Water Heater Leak

Water pooling around a tank-style water heater or a continuously running relief valve indicates the unit is at or near end of life. BC water heaters typically last 10-15 years, and failure is often sudden, releasing a large volume of water that can cause extensive flooding.

Possible Causes

  • Corrosion failure of the inner tank (most common end-of-life failure)
  • Failed temperature and pressure (T&P) relief valve
  • Loose or corroded drain valve
  • Failed inlet/outlet water connection fittings
  • Condensation from cold water entering the tank (usually temporary)

Recommended Steps

  • 1Check if water is from a leaking fitting (tighten or replace) or the tank itself (likely imminent failure)
  • 2If the tank is leaking, shut off the water supply and gas/electric to the unit
  • 3Place a pan or hose to direct water to a drain if possible
  • 4Call a plumber for replacement — most BC municipalities require permits for water heater replacement
