Qb.
If you have copper piping to the water
heater, the two €opper 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 two galvanized pipes
with a pipe wrench at the union in.each
line. Also disconnect the piping remain-
ing to the water heater. These pieces
sh6uld be saved since they may be need-
ed when reconnecting the new water
heater. Disconnect the remperamre-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
