hi all.

i need to reattach an impeller to a magnet in a malfunctioning hob power filter. i suppose most of you would use silicone to do this; i've got about a dozen unusable tubes with about 1% gone out of them in the basement to attest to this. so, my question is, is it ok to use a common household adhesive, such as krazy glue, for this purpose?

sorry if this seems like a super lame question (maybe i've been listening to too much robert plant today), but i have never seen it addressed anywhere. krazy glue seems to dry extremely hard and i wouldn't think that, when hardened, it would be water soluble.

i am not expecting a general answer, ie yes or no, since there are several formulations of krazy glue and other brands as well. i would appreciate you sharing any experiences, good or bad. thanks.

I've used crazy glue to glue the magnet back on to the impeller on whisper filters. Works great. lasts longer than original! crazy glue is non-toxic once cured.

excellent! that's the exact type of filter i was going to try to fix. once they become noisier, the problem is usually the impeller/magnet assembly, correct?

epoxy should also be non toxic when cured, but takes 24 hours to fully cure usually.
If it was me I'd just buy a new impeller assembly for $5
