Do you live in a hard water area and suffer from lime scale on sinks, faucets and showers? This is because your water supply contains dissolved magnesium, calcium, manganese compounds which appear as troublesome lime scale. They form into hard deposits settling on the surfaces of sinks, faucets, pipes and inside appliances, creating restrictions and greatly reducing the efficiency of water heaters and furnaces.   Eddy is easy for anyone to fit, requires NO plumbing changes, does not require any salt and costs a fraction of the price of a conventional salt-fed water softener.   Eddy produces a complex electro-magnetic wave which is applied through two coils placed round your incoming water supply pipe. In this way your water is subjected to an ever changing magnetic field as it passes through the coils. This alters the adhesion properties of the limescale so that it no longer deposits itself on your clean surfaces, inside pipework and appliances.   Eddy does NOT alter the chemical hardness (TDS) of the water so the beneficial effects of the calcium and other particulates is retained - for example, calcium has been shown in medical tests to reduce incidence of heart disease.  Eddy has been successfully used worldwide in thousands of homes and businesses for over 15 years, is highly economical and in most cases represents an easy eco-friendly alternative to salt-based water softeners.   It is effective on all types of water pipe (except lead and iron) and is the only descaler to come with a risk-free, no-quibble 12 month money-back guarantee and a Lifetime repair or replace guarantee.  Thousands have been sold for use in homes and businesses. Buy with confidence.  Comes with standard cables for pipe diameters up to 1.5 inches.
