A*Condensation may be seen on pipes 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.

D.*The temperature-pressure relief valve may be leaking at the tank fitting.

E. Water from a drain valve may be due to the valve being slightly opened.

F.*The drain valve may be leaking at the tank fitting.

G.Leakage from recirculation plug or pipe connection.

*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.
