Some would suggest taking it off and getting your money back

There have been very few proper scientific studies on the effectiveness of magnetic water softners. As far as I can tell there is no scientific reason to think magnets might work let alone really good evidence they do...
http://en.wikipedia.org/wiki/Magnetic_water_treatment Quote:Most scientific studies[6] do not support these claims and suggest that magnetic water treatment may be ineffective. Certainly many, perhaps most claims for small domestic apparatus may be pseudoscientific because the magnetic field, if it works at all, would have to be very powerful, and this high flux is not easily achieved in a small space.
Quote:Scientific and engineering studies generally refute the effectiveness of the method, finding no differences not attributable to other causes between systems with and without a magnetic water treatment device, and no theoretical basis to expect that there might be. Vendors frequently use pictures and testimonials to support their claims, but omit quantitative detail and well-controlled studies.
The only exception to this is the use of magnets to remove sludge from central heating systems. There is a scientific reason why they might work in that application and that's because some of ithe sludge is "rust" from the inside of iron/steel rads.
