OF YOUR
WATER
HEATER
Draining and Flushing
The water heater should be drained if being shut down
during freezing temperatures.
It is recommended
that
the tank be drained, and flushed every 6 months to
remove sediment which may buildup during operation.
To drain the tank perform the following steps:
1. Turn off the power to water heater.
2. Close the cold water inlet valve and open a nearby
hot water faucet.
3. Connect a hose to the drain valve and terminate it
to an adequate drain.
Important:
Drain hose should be rated forat least 200°F.
If the drain hose does not have this rating, open the cold
water inlet valve and a nearby hot faucet until water is no
longer hot.
4. Open the water heater drain valve and the nearest
hot water faucet. Allow all the water to drain from the
tank. Flush the tank with water as needed to remove
sediment.
5. Close the drain valve, refill the tank, and restore
power.
If the water heater is going to be shut down for an
extended period, the drain valve should be left open.
