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. NOTE: Cover and Insulation shown removed to reveal tank top

Where possible remove or lift top cover to examine threads of fittings installed into tank for evidence of leakage. Correct fitting leaks as necessary.

Water leaks at the elements may be due to:

1.Defective element which leaks at terminals or thru flange. Replace element*.

2.Loose element/gasket leak:

(a)Screw-in type: tighten with 1-1/2” socket wrench or Part Number 23985 wrench. If leak continues, remove element*, discard gasket and clean thread areas.Apply nonhardeningPermatex Number 2 to thread areas, install new gasket and screw element into fitting until it seats. Tighten 1/2 to 3/4 turn with wrench.

(b)Flange type: tighten screw with wrench. If leak continues remove element* and discard gasket. Clean gasket seating areas and re-install element with new gasket. NOTE: Part Number 40000-1 scale cleaning replacement screws available where threads have become rusted or damaged, preventing tightening.

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 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 proven otherwise.

Relief Valve

To Open Drain

Condensation and dripping may appear on pipes when cold water temperature is low. Pipe fitting may be leaking.

Anode Rod (Some Models)

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 material between jacket opening and swab spud area. Remove valve* if indicated and repair with pipe joint compound.

To Open Drain

Water on the side of the tank may be condensation due to the panel or insulation not being in place.

Drain valve leakage could be from the valve itself.* 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.
