Also just a passing thought .. those furnace humidifier float valves run on household pressure which can be anywhere from 60-100 psi. You don't hear of them of failing very often and when you do, you can usually trace it back to "improperly maintained and/or installed", ie. human error. The orifice that the water passes through is extremely small (less than 1mm) so it doesn't take much to hold back water through that hole. The flipside is that because the hole is so small, if there is any particulate in the water, or kalk, it will gum up very easily and then water can't pass though anyhow.
