If your tank is manufactured by one of the three most common brands in the Greater Victoria area (Bradford White, John Wood, or Rheem) then see our guide below. Note that the major manufacturers usually only include a 1-2 year warranty on other parts. If you have extended warranty documentation, your tank may have a longer warranty. Most hot water tanks manufactured after 2003 have an 8-year warranty against leakage. Most hot water tanks manufactured before 2003 have a 6-year warranty against leakage.
