The cpvc shouldn’t be the concern. What is of concern are the plumbing fitting in your house it’s always possible for a leak especially when the pressure gets too high.
The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater, preventing excessive water pressure in your home. If the water pressure gets too high it can damage valves and plumbing fixtures, joints and supply pipes and the water heater it’s self.
Bottom line if your expansion tank is more than five years old and it tests good , replace it don’t wait for the failure.
