LEAKAGE CHECKPOINTS
Read this manual first. Then before checking the water heater 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. The anode rod fitting may be leaking.
C. 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.
*D. The temperature-pressure relief valve may be leaking at the tank
fitting.
E. The element may be leaking at the tank fitting. Turn electrical power
“OFF”, remove outer door, insulation block and pad. If leaking
around the element, follow proper draining instructions and remove
element. Reposition or replace gasket on element. Place element
into opening and tighten securely. Then follow “Filling the Water
Heater” instructions in the “Installing the New Water Heater”
section.
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 fitting.
*H. 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.
