DRAINING THE WATER HEATER
Warning:
Exercise care, as water discharged from the water heater may be
of a very high temperature.
To drain the water heater:
•
Turn off the water heater (refer to “To Turn Off The Water Heater” on
page 42).
•
Close all hot water taps.
•
Operate the relief valve easing lever - do not let the lever snap back or you
will damage the valve seat.
Operating the easing 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 easing lever again.
This will let air into the water heater and allow the water to drain through the
hose.
