A. Water at the draft hood 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 tting may be leaking.
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 tting.
F. Water from a drain valve may be due to the valve being
slightly opened.
G. *The drain valve may be leaking at the tank 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 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 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.
*To check where threaded portion enters tank, insert cotton
swab between jacket opening and tting. If cotton is wet,
follow the instructions in Draining and Flushing (page 32)
and then remove tting. Put pipe dope or teon tape on the
threads and replace. Then follow the instructions in Filling
the Water Heater (page 15).
