Leakage Checkpoints
INSTRUCTIONS: USE THIS ILLUSTRATION AS A GUIDE WHEN CHECKING FOR SOURCES OF WATER LEAKAGE. YOU OR
YOUR DEALER MAY BE ABLE TO CORRECT WHAT APPEARS TO BE A PROBLEM.
Where possible, remove or lift top cover to
examine threads of fittings installed into tank for
evidence of leakage. Correct fitting leaks as
necessary.
Relief valve operation and leakage may be due
to water expansion during heating cycle or foreign
material on seat of valve. If the valve is not piped
to an open drain, the released water could be
mistaken for a leaking heater. To check where
threaded portion enters tank, insert Q-tip or
similar absorbent material between jacket
opening and valve to swab spud area. Remove
valve* if leak is indicated and repair with pipe joint
compound.
Water on the side of the tank may be
condensation due to the panel or insulation not
being in place.
Water leaks at the elements may be due to:
1. Defective elements which leak at terminals
or through flange. Replace element*.
2. Loose element/gasket leak:
Tighten element with element wrench. If leak
continues, remove element* and discard
gasket. Clean gasket seating areas and
reinstall element with new gasket.
Condensation and dripping may appear on pipes
when inlet water temperature is low. Pipe fitting may
be leaking.
All water which appears at the heater bottom or on the
surrounding floor may be caused by condensation, loose
connections or relief valve operation and leakage. Do not replace
the heater until a full inspection of all potential leak points is
made and corrective steps taken to stop the leak. Leakage from
other appliances, water lines, or ground seepage should also
be suspected until proved otherwise.
Drain valve leakage could be from the valve itself.
Either correct the problem or replace the valve*. To
check for leakage where threaded portion enters tank,
insert Q-tip or similar absorbent material between
jacket opening and valve to swab spud area. Remove
valve* if leak is indicated and repair with pipe joint
compound.
* Contact your dealer as it is necessary to shut off
electricity and drain tank to perform procedure.
