a. If you have copper piping to the water
heater, the two copper water pipes can be
cut with a hacksaw approximately
4"
away from where they connect
to the
water heater. This will avoid cutting off
the pipes too short. Additional cuts can
be made later if necessary. Disconnect
the temperature-pressure
relief valve
drain
line. When
the water heater
is
drained,
disconnect
the hose from the
drain valve. Close the drain valve. The
water heater is now completely
discon-
nected and ready to be removed.
If you have galvanized pipe to the water
heater, loosen the twogalvanized
pipes
with a pipe wrench at the union in each
line. Also disconnect the piping remain-
ing to the water heater. These pieces
should be saved since they may be need-
ed when reconnecting
the new water
heater. Disconnect the temperature-pres-
sure relief valve drain line. When the
water heater is drained, disconnect
the
hose from the drain valve. Close the
drain valve. The water heater
is now
completely disconnected and ready to be
removed.
AWARNING
The water passingout of the drain valve may be extremely
hot. To avoid being scalded, make sure all connections are
tight and that the water flow is directed away from any
pelTton.
