Routine Preventive Maintenance
DANGER
Risk of Scald - Before manually
operating the relief valve, make certain no one will
be exposed to the danger of coming in contact with
the hot water released by the valve. The water may
be hot enough to create a scald hazard. The water
should be released into a suitable drain to prevent
injury or property damage.
NOTE: If the temperature and pressure-relief valve
on the hot water heater discharges periodically, this
may be due to thermal expansion in a closed water
system. Contact the water supplier or your plumbing
contractor on how to correct this. Do not plug the
relief valve outlet.
Properly maintained, your water heater will provide years
of dependable trouble-free service. It is suggested that
the following yearly preventive maintenance program be
established.
1. Inspect Temperature & Pressure Relief Valve.
2. Inspect heating elements, TCO, and wiring to each.
3. Drain and Flush the water heater tank.

Draining and Flushing the Water Heater
CAUTION
Risk of Shock - Shut off power to
the water heater before draining water.
DANGER
Risk of Scald - Before manually
operating the relief valve, make certain no one will be
exposed to the hot water released by the valve. The
water drained from the tank may be hot enough to
present a scald hazard and should be directed to a
suitable drain to prevent injury or damage.
A water heater’s tank can act as a settling basin for solids
suspended in the water. It is therefore not uncommon for
hard water deposits to accumulate in the bottom of the tank.
To clean the tank of these deposits, it is recommended to

the water heater, follow these steps:
1. Turn off power to the unit. The electric heating elements
will become damaged if operated without water.
2. Attach a garden hose to the drain valve located at the
bottom of the unit and direct that hose to a drain.
3. Turn off the cold water supply.
4. Admit air to the tank by opening a hot water faucet or
lifting the handle on the relief valve.

a nearby open hot water faucet.
Flushing should be done with an empty tank to promote
additional removal of sediment.
