1). Salt.Top up with salt every few months. Brockley Plumbers carry out servicing of all appliances.2). Prevent Contamination.Regulations insist that a non-return valve must be fitted between the water softener and the stopcock from the rising main to prevent any contamination to the drinking water supply.3). Drinking Water.The cold water tap in the kitchen is taken from the rising main at a point between the stopcock and the non-return valve so that drinking and cooking water is not treated and still provides the beneficial minerals.4). Garden Tap. If there is a connection to a garden tap, this should also be taken from the rising main between the stopcock and the non-return valve otherwise you will be spraying costly softened water over the garden.5). Servicing.The water softener will need servicing at some stage so it is a good idea to install a valve to turn off the water softener and open a by-pass valve that will provide a supply of unsoftened water while the unit is out of commission.6). Savings.Although expensive, the water softener will ensure that you use less washing powder in the washing machine (less wear and tear on clothing) and dishwasher whilst lengthening the life of your pipework and heating system.7). Draincock.You will need to fit a draincock in the rising main just above the non-return valve as the valve will allow water to be drained from any point above. 8). Standpipe.On the wastewater side of the water softener you need to install a standpipe for the waste hose to sit in just like a washing machine.9). Waste Connection.If you use a waste connection that links to the trap under the sink, fit an anti syphon and non-return valve to prevent dirty sink water being sucked back into the Softener.10). Fused Connection Unit.The water softener must be connected via a fused supply. This should be carried out by a professional. A Brockley Plumber can advise on this.
