Use this guide to check a "Leaking" water heater. Many suspected
"Leakers" are not leaking tanks. Often the source of the water can be
found and corrected.
If you are not thoroughly familiar with gas codes, your water heater,
and safety practices, contact Sears Service Center to check the water
Read this manual ﬁ rst. Then before checking the water heater make
sure the gas supply has been turned "OFF", and never turn the gas "ON"
before the tank is completely full of water.
Never use this water heater unless it is completely ﬁ lled with water. To
prevent damage to the tank, the tank must be ﬁ lled with water. Water
must ﬂ ow from the hot water faucet before turning "ON" gas to the water
A. Water at the blower assembly is water vapor which has condensed
out of the combustion products. This is caused by a problem in the
vent. Contact the gas utility.
B. *Condensation may be seen on pipes in humid weather or pipe
connections may be leaking.
C. *The anode rod ﬁ tting may be leaking (anode is located under the
D. Small amounts of water from temperature-pressure relief valve may
be due to thermal expansion or high water pressure in your area.
E. *The temperature-pressure relief valve may be leaking at the tank
F. Water from a drain valve may be due to the valve being slightly
G. *The drain valve may be leaking at the tank ﬁ tting.
H. Combustion products contain water vapor which can condense on
the cooler surfaces of the tank. Droplets form and drip onto the
burner or run on the ﬂ oor. This is common at the time of start-up
after installation and when incoming water is cold.
I. Water in the water heater bottom or on the ﬂ oor may be from
condensation, loose connections, or the relief valve. DO NOT replace
the water heater until a full inspection of all possible water sources
is made and necessary corrective steps taken.
Leakage from other appliances, water lines, or ground seepage should
also be checked.
To check where threaded portion enters tank, insert cotton swab
between jacket opening and ﬁ tting. If cotton is wet, follow "Draining"
instructions in the "Periodic Maintenance" section and then remove
ﬁ tting. Put pipe dope or teﬂ on tape on the threads and replace.
Then follow "Filling the Water Heater" instructions in the "Installation
