The maintenance activities described below are only to be
performed by the Installer / Qualified Service Provider. These
maintenance items should be performed during recommended
annual service and any service calls.
1. Ask the owner / user if there have been any issues with the
water heater. Diagnose any heater issues and repair / replace
parts as necessary.
2. Check the water heater and related plumbing for leaks. Repair
any that are found.
3. Check the area around the water heater for flammable liquids
or combustible materials. If any are found, remove from the
area.
4. Check the heating elements while the heater is in operation. If
the elements are hissing / singing excessively, they may need to
be cleaned. Inspect the elements and clean if necessary.
5. Inspect the Temperature and Pressure (T&P) Relief Valve. See
instructions below.
6. Turn power supply off to the water heater. Open the drain
valve and drain a few gallons of water from the tank to clear any
hard water deposits. Once complete, close the drain valve and
restore power to the water heater.
T&P Relief Valve Maintenance Instructions:
• Annually: Certain naturally occuring mineral deposits
may adhere to the valve, blocking waterways and
rendering the valve inoperative. The T&P Relief Valve
lever must be operated to ensure the waterways are
clear. If waterways are clear, hot water will discharge
from the valve. Take precautions to avoid personal injury
and property damage from contact with hot water.
Before operating lever, check to see that a discharge line
is connected to the valve, directing the flow of hot water
from the valve to a proper place of disposal.
• Replacement of the valve is required if no water flows
when the lever is operated. Turn the water heater off
until the valve is replaced.
• If water flows from the valve, drain a few gallons from
the tank to ensure the water flows freely.
• At least once every three years: To ensure that the T&P
valve has not been affected by corrosive water conditions
and that the valve and discharge line have not been
altered or tampered with illegally, relief valves should
be inspected, and replaced, if necessary, by a licensed
plumbing contractor or qualified service technician.
Failure to comply with these guidelines could result in failure
of relief valve operation, and possibly result in substantial
property damage, severe personal injury, or death.
