Temperature & Pressure
Relief Valve
Cover and Insulation shown removed to reveal tank top
Anode Rod
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)
(b)Flange type: tighten screws with wrench. If leak continues remove element* and discard gasket. Clean gasket seating areas and reinstall element with new gasket.
NOTE: Part No.
All water which appears at the heater bottom or on the surrounding floor may be caused by condensation, loose connec- tions 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 proven otherwise.
To Open Drain
Condensation and dripping may appear on pipes when cold water temperature is low. Pipe fitting may be leaking.
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
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. Either correct the problem or replace the valve.* To check for leakage where threaded portion enters tank, insert
