    Looks like a back flow preventer.

    To add to what Ken said, that is an RPZ backflow preventer.

    Why would someone put a backflow preventer in a residential structure as opposed to a standard regulator?

    Most public water suppliers now require backflow preventer's.
    First on the list are industry, business, new homes , then everyone.
    High on the list are lawn sprinklers.

    It's very common across the USA for BP's to be required.
    It is an EPA mandate.

    And to add:
    Don't confuse a backflow preventer with a regulator.
    They are not the same.

    When a RPZ is working properly and a backflow condition exisits....there is a port on the bottom of the device that discharges water. That could have been the spraying you saw.

    "When a RPZ is working properly and a backflow condition exisits....there is a port on the bottom of the device that discharges water. That could have been the spraying you saw"

    Kinda, sorta, correct.
    An RPZ releases water to prevent backflow, not because there is backflow.
    Before there is back-pressure in the middle chamber, the RPZ will release water at the port. This lowers pressure in the middle chamber, preventing backflow.

    MY point was just because it is leaking water does not mean it is faulty.
