cut with a hacksaw approximately 4"
away from where they connect to the

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.

heater, loosen the twogalvanized pipes
with a pipe wrench at the union in each
