What is the water hardness in my area?

Hard water is caused by calcium and magnesium compounds; rain water is naturally soft as it has had no chance to pick up any minerals from the ground. When water passes through the ground through soft rocks like chalk or limestone, it picks up these minerals. If the water passes through rocks such as granite or through peaty soil calcium and magnesium are picked up and so the water remains soft.

Hard water can create 2 main issues within a building: Issues Relating to Scale Heat causes the calcium and magnesium to precipitate out of the water and stick to things causing "scale" to form on the inside of pipes,Guest Posting water boilers, tea kettles and so on. The scale doesn't conduct heat well and reduces the flow through the pipes which can ultimately become completely blocked potentially leading to expensive repair bills. Reducing the Effectiveness of Soap Hard Water reacts with soap to form a scum and (in extreme cases) reduces soap's ability to lather, this impacts on cleaning throughout the house including washing, bathing and general cleaning. Hard and Soft Water Regions in the UK The list below is a good indication of the general hard and soft water areas in the UK although it is an indicator only as all areas can contain pockets of completely different water types. To find out more you can contact your local water company (see list at base of article).

If installing a water softener is too difficult or costly then you could consider protecting specific devices that are plumbed into the mains with a scale inhibiting filter. The types of devises that may be protected in this way include mains water coolers and all types of water boilers and heaters. These filters are installed inline between the mains pipes and the machine itself and contain scale inhibiting elements. About Water Softeners A Water Softener is a device that monitors and reduces the hardness of the water, it does this by removing the calcium and magnesium salts from a water supply and replacing them with a saline solution. All water softeners work in essentially the same way, the incoming water enters the softener and passes through ion exchange resin. The resin removes the magnesium and calcium ions that create lime scale by swapping them with a small amount of salt, this leaves the softened water to enter your water system. The machines often contain an automatic timer control which will periodically clean or regenerate the resin. This is done by passing salt water through the resin which swaps places with the stored magnesium and calcium ions and allows the trapped minerals to be flushed down the drain. If you are considering this option then please be aware: When installing your Water Softener the UK Water Bylaws require that one tap in the house is left unsoftened. This may be accomplished by installing a third dedicated tap at the kitchen sink. In effect the whole house has softened water and the dedicated tap provides hard water for drinking, cooking etc. It’s also recommended that any outside taps are fed with unsoftened water to avoid waste.There is evidence of less heart disease in hard water areas than in soft water areasMost water softeners work by replacing the hardness with sodium which can cause issues with babies and those with heart conditions Some water supplies contain impurities that may affect your softener if left untreated. Iron, dirt, silt, organics and bio film may not be removed by the salt regeneration system and older resin beds may start to suffer from iron fouling. Soft water can release lead from any lead pipes Once the scale is removed it can open up old leaks that have been sealed by the historic scale build-upSofteners require ongoing maintenance and need to be topped up with the correct type of saltYou purchase the system from a reputable supplier
