Pictures would be helpful.
Who are you asking? The piggybacker?

If you're asking me, then its a VFD setup. I will have to apologize if the VFD method doesn't use a pressure switch. I just "assumed" that that is what was used.

VFD uses some fairly high-end electronics to control the pump. I think a pressure tank CSV combo is better because there is less complexity and fewer failure points but either way, I still wouldn't worry about a PVB doing what it's designed to do.

VFD uses a pressure transducer, or pressure transmitter as called in this VFD lesson.
