Attach a hose to the water 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 WARNING
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.
a. If you have copper piping to the water heater, the two
copper water pipes can be cut vrith a hacksaw approxi
mately 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 neces
sary, Disconnect the temperature-pressure relief valve
drain line. When the water heater is drained, discon
nect the hose from the drain valve. Close the drain
valve. The water heater is now conapletely disconnect
ed and ready to be removed.
b. 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
should be saved since they may be needed
when reconnecting the new water heater.
Disconnect
the
temperature-pressure
relief valve discharge pipe. 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.
Check again to make sure the electrical supply is turned
“OFF” to the water heater. Then disconnect the electri
cal supply connection from the water heater junction

in the old water heater. This causes the water
heater to be much heavier than normal and this
residue, if spilled out, could cause staining.
