If it's the motor part of the valve, this can usually be replaced
without plumbingy work.

If it's the valve part, it's a drain-down job.

And if the actuator does not remove with a couple of screws (like my old
one) the valve is long overdue for replacement, which is just as well
considering you've got to.

Still not a very difficult job as jobs go!
