Yes certainly, I think in a house with high water pressure it will have
little effect, the lower the pressure the more it will simply clog up pipes
until something goes wrong.
Then the scale will just return but your pipes aware probably scaled up. It
also depends on the makeup of the actual calcium or bits of old concrete
and plastic in the water, and since there is no way to get the clumped stuff
out its just going to go to the nears place it can lodge all clumped
together.
I personally feel that water treatment plants are the place where water
should be made limescale free if you believe that is more healthy.
Bah humbug.

Personally, I think the whole thing to be bollox.

Does anybody know the physics behind it?

It's something to do with money changing hands, perhaps?




I cannot see how orienting the calcium saly ions
in one particular direction will stop furring up
some distance away especially if there has been
turbulent flow in between.

I advised him to get a water softener fitted instead.
