The reason for the electrial change, (if i go with the bladder tank) is
because
the pressure swicth is on top of the tank right now. The bladder tank setup
has
the pressure switch just off the floor. I will need to run a new line down
to the floor.
Not a big problem.

The plumbing change is because my (non-bladder tank.) has a pipe going in on
one side,
and a pipe coming out on the opposite side. With the bladder tank, I must
install a brass tee
(not included with the tank) into the bottom of the bladder tank, the detour
the in and out
water pipes into the tee. Also I need a pressure relief valve. When it's all
added up,
it gets a little expensive to make the detour with the exsisting plumbing.
