A water softener is used when a property is in what is called a hard water area. This means that the water contains minerals that sediment out when the water is heated, coating pipework and ruining your white appliances, showers, and be boilers etc. whilst this is bad for your appliances is not bad for you, in fact hard water is much better for you than soft water, as the minerals that damage your white appliances are the same minerals that bottled water suppliers sell. So when you fit a water softener you need to ensure that at least one tap still supplying drinking water, if you don’t want to soften all the water in your home. Lambeth Plumbers can fit this unit. If you have an indirect water supply system, the water coming into your house to the rising mains straight up to the cold water storage tank in the loft, with a branch off to your kitchen tap, the water softener diverts this cold water feed through the softener treatment tank before returning it to the pipe that feeds the cold water storage tank in the loft.So the water that is used pretty much throughout the house which includes the CH system, hot and cold water to bathrooms and to the WC cistern, are being treated by the softener. You can connect the WC cistern directly to the rising main before the softener, and fit a nozzle in the ballcock valve in the WC cistern. As a lot of water is used when flushing. and although sometimes it might be necessary to use a descaling solution in the WC pan, the consumption of softened water will be considerably reduced by this action. A Lambeth Plumber can service this appliance.Connect:Work from under the sink, fit a one-way valve with the flow heading into the house, a small drain-cock, for the feed, a service valve to divert the water flow through the softener (in case of snags with the unit) and another washing machine style tap (the return from the water softener). The best valves have a quarter turn action, fitted with a knob that indicates whether the valve is open or shut.
