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.
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.
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 a Qualified Service Agency as it is
necessary to shut off electricity and drain tank to
perform procedure.
