This document:

based on research from WRc (if I remember correctly, the now-
privatised Water Research Centre labs) that physical conditioning
devices do *indeed* work, but that the scale-reducing effect cannot
be guaranteed.

Which is not quite the same as "useless" - more a case of "suck it
and see".


The document is liberally sprinkled with the words "if", "might",
"maybe"

The WRC reference is worthless because it only relates to whether
conditioners do or don't conform to regulations and is not related to
fitness for purpose.

There is only one PC device that
has passed the German DVGW tests and
this is not the typical type of £30-90
device that is sold.

These are useless.

That is not what the WRC say.

There are a sufficient number of caveats, exceptions, maybes, and
"might work" but circumstances undefined and undefinable, that they
are doing nothing more than being kind.

As I said. Useless.

Assertion is not proof.
