    I have not seen that requirement, but codes differ in different states

    For the minor cost of having a back up low water cut off, I always recommend it. I don't think typical codes in the US require it.

    If you do install a second one, have it on it's own pigtail. They clog very easily. - oops, I was thinking pressuretrols.

    No but it is a belt and suspenders theory
    I like a probe type and a manual flush type.  MD

    Oops. You know what I was thinking, Paul. In NYC two pressure controls (one manual reset) are needed for many installations.
