LEAKAGE CHECKPOINTS

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.

FIGURE 12.

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.
