    If one house in 100 in california has a thermal expansion tank, I would be very surprised.

    I save them for closed boilers and radiant heat systems.

    And in the country, the house without a pressure reducing valve has all the outdoor plumbing and the well expansion tank to absorb those small expansion issues.

    The most reliable expansion tank is a hose dripping a bit over the dogs water bowl.
