A client is experiencing periodic dramatic drops in water pressure. Perhaps 80% sudden pressure reduction that goes away after around 30 minutes.

I've read of pressure regulators
sometimes being in place to prevent massive pressure from damaging sink faucets. But I've had no experience with them.

The house was built approximately 1950, this unit also contains the shut off valve. Seems like possibly a good place to look first.
