    The limescale preventer came well packed & very quickly after it had been ordered. Installation was very easy. No problems.

    I hung this in the water tank near the inlet from a spare length of copper pipe. It is therefore only effective for water coming from the hot tap, or cold water for showers which is taken from the header tank. Within a day or two, we seemed to need less shampoo, and fittings in the shower did not scale up as quickly - but they do still scale up. Fernox recommend replacing every six months, and this may be what is needed in a hard water area we are on our third. So not totally effective, but good enough to be worth the cost compared with installing and running a water softener.
