Installing new water heater

I'm looking for advice on necessity of a back-flow valve and expansion tank in a well-supplied system. It is a new construction, with a pump and pressure tank already in place.
Thanks in advance

Your well tank would act as an expansion tank.

Probably don't need back-flow because ft valves and or check valves would be in the system alreadyif a well.
