Read this manual first. Make sure the electrical power supply has
been turned “OFF” before checking the tank for leakage.
*A. Condensation and dripping may be seen on pipes if the water
temperature is low in humid weather or pipe connections may
be leaking.
B. Small amounts of water from temperature-pressure relief valve
may be due to thermal expansion or high water pressure in your
area. If the valve is not piped to an open drain the released
water could be mistaken for a leaking heater, see “Thermal
Expansion” section.
*C. The temperature-pressure relief valve may be leaking at the
tank fitting.
D. Water on the side of the tank may be condensation due to the
panel or insulation not being in place.
*E. Water in the water heater bottom or on the floor 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 fitting. If cotton is wet, follow
“Draining” instructions in the “Periodic Maintenance” section
and then remove fitting. Put pipe dope or teflon tape on the
threads and replace. Then follow “Filling the Water Heater”
instructions in the “Installing the New Water Heater” section.
