    Well, now

    that's what the low water cut off is designed and intended to do.  However we need a lot more information as to why the water gets low.



    You say it comes back eventually?  To the same level as before?  Or is it necessary to add water each time to bring it back up to where it should be?  And, if that is so, does it then become too full?



    I gather from your remark that this is something which only recently started happening.  If that is so, what, if anything, has changed?

    info

    As Jamie said we need more information.

    You could have:

    a leaky boiler above or below the water line

    a dirty boiler causing the water level to bounce

    Incorrect piping?

    a leaking underground return

    leaking air vents or other leaks

    partially plugged low water cutoff connections

    and the list goes on.....................................
