Many water pipes are
connected by a threaded
union which can be disconnected with
wrenches. If you must cut the water
pipes, cut the pipes close to the water
heater's inlet and outlet connec ons,
leaving the water pipes as long as
possible. If necessary, you can make
them shorter later when you install
the new water heater.
