Draining The Water Heater - Rheem 300 series Installation Instructions Manual

DRAINING THE WATER HEATER

To drain the water heater:
•
Turn off the water heater (refer to
page 23).
•
Close all hot water taps.
•
Operate the relief valve release lever - do not let the lever snap back or you
will damage the valve seat.
Operating the lever will release the pressure in the water heater.
•
Undo the union at the cold water inlet to the water heater and attach a hose
to the water heater side of the union.
Let the other end of the hose go to a drain.
•
Operate the relief valve again.
This will let air into the water heater and allow the water to drain through the
hose.
