Water Heater Warranty Check

Most hot water tanks manufactured before 2003 have a 6 year warranty against leakage, and most hot water tanks manufactured after 2003 have an 8 year warrant against leakage. If you have extended warranty documentation, then your tank may have a longer warranty.

Note that the major manufacturers usually only include a 1-2 year warranty on other parts, besides the tank itself.

How to tell how old your tank is

If your tank is manufactured by one of the three most common brands in the Greater Vancouver area (Bradford White, John Wood, or Rheem) then see our guide below. If your hot water tank was not manufactured by one of these 3 brands, then see this guide to determine your tank’s age.


John Wood/ GSW

John Wood hot water tanks start with a letter that reveals how long the warranty against leakage is. P = 3 years, R = 5 years, S = 6 years, T = 7 years, U = 8 years, V = 9 years, W = 10 years, and Y = 12 years.

Following the first letter will be four numbers that refer to the date of manufacture. The first two numbers refer to the year of manufacture. 95 would be 1995, 98 would be 1998, 02 would be 2002, 08 would be 2008, and so on.

For tanks made before 2007, the next two numbers refer to the month of manufacture. 01 = January, 02 = February, 03 = March, and so on. Serial numbers on John Wood tanks made in 2007 or earlier consist of a letter followed by 10 numbers. For example, a serial number of U0508482157 would mean the tank was made 2005 (the first two numbers are 05), in the month of August (the next two numbers are 08), and includes an 8 year warranty against leakage (the first letter is U).

For tanks made in 2008 or later, the next two numbers refer to the week of manufacture. 01 = first week of the year, 02 = second week, and so on. Serial numbers on John Wood tanks made 2008 and later consist of a letter followed by 4 numbers followed by another letter and 6 more numbers. For example, a serial number of U0923C239421 would mean the tank includes an 8 year warranty against leakage (the first letter is U) and was made in 2009 (the first two numbers are 09) in the 23rd week (the next two numbers are 23) of that year.

Rheem/ Ruud Hot Water Tanks

The first two numbers refer to the month of manufacture (01 = January, 02 = February, and so on) and the next two numbers refer to the year (97 = 1997, 05 = 2005, and so on). This is followed by a letter and 5 more numbers. For example, serial number 0307B94210 would mean the tank was made in March (the first two numbers are 03) of 2007 (the next two numbers are 07).

Bradford White Hot Water Tanks

The first two letters of the serial number correspond to the year and month of manufacture.

A = 1984 or 2004
B = 1985 or 2005
C = 1986 or 2006
D = 1987 or 2007
E = 1988 or 2008
F = 1989 or 2009
G = 1990 or 2010
H = 1991 or 2011
J = 1992 or 2012
K = 1993 or 2013
L = 1994 or 2014
M = 1995 or 2015
N = 1996 or 2016
P = 1997 or 2017
S = 1998 or 2018
T = 1999 or 2019
W = 2000
X = 2001
Y = 2002
Z = 2003
A = January
B = February
C = March
D = April
E = May
F = June
G = July
H = August
J = September
K = October
L = November
M = December

For example, a serial number starting with CL would have been manufactured in November of 1986 or 2006.

What your warranty covers

Remember that while the major manufacturers usually include 6-8 year warranties against leakage, other components are only covered for 1-2 years. If a tank is still covered under warranty, you will still have to pay labour and possibly warranty processing fees as well (unless the company who installed your tank included a labour warranty).

If you have the original invoice for your water heater installation, then the start date of your warranty may be from the date of installation rather than the date of manufacture.

If you are still unsure whether your tank is still under warranty or not, then call 604 GOOD GUY (604 466 3489) and we can assist you.
