If you have copper piping to the water heater, the two
copper water pipes can be cut with a hacksaw approximately
four inches 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 disconnected
and ready to be removed.
FIGURE 5a.
5b. 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 remaining to the water heater.
These pieces should be saved since they may be needed
when reconnecting the new water heater. 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
disconnected and ready to be removed.
