For how long does the Eddy water treatment remain effective?
Depending on the degree of your water hardness, we would normally expect water treated by Eddy to retain its beneficial properties for up to 72 hours after treatment. This is more than adequate in a house with normal water consumption to ensure that any water in the main loft storage tank and hot water cylinders is fully replenished before the benefits of treatment wear off. In houses with very low water consumption you may wish to consider fitting the Eddy unit to the “exit” pipe from the main water storage tank, though bear in mind that this may mean that not all areas of the house may be treated, i.e. those areas that take a feed of water directly from the water main (often the kitchen).
