Removing the Old Water Heater
ADANGER
Burn hazard
Hot water discharge.
Keep hands dear of drain
valve discharge.
The water passing out 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 person.
Check again to make sure the electrical supply is turned
“OFF” to the water heater. Then unplug the water heater
(cord set) or disconnect the electrical supply connection
from the water heater junction box.

Turn “OFF” the wafer supply to the water heater at the water
shut-off valve or water meter.
FIGURE 3.
(^Attach a hose to the wafer heater drain valve and put the
other end in a floor drain or outdoors. Open the water heater
drain valve. Open a nearby hot water faucet which will relieve
pressure in the water heater and speed draining.
a. If you have copper piping to the water heater, the two
copper wafer 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 wafer 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.
b. If you have galvanized pipe to the wafer 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.
