Found this in a 1956 duplex under the kitchen sink, forgot to check which tap it was connected to, but its on the rights side feed pipe. The unit did not feel hot to the touch. The apartment has a hot water tank in the basement and the wire feeding this gizmo was hot. Any ideas?
Many years ago there was a super sales person who sold a water softener that never needed salt and never
needed recharging it was a magnet and it did not work .
I have never seen one but expect this is what you found.
