Water Pollution

The presence of dirty and polluted water is probably the world’s largest risk to health and as long as it exists it will pose a significant threat to the health and well-being of the general public. Acton Plumbers fit all types of appliances. As rainwater and snow that melts runs from the roofs and roads and filters into the river network, it will definitely take with it toxic material and bacteria as it goes. The waterways we love so much are not well protected, so I really very vulnerable from contaminants coming from industry and farms and of course the new drilling process known as tracking. The dangers out of the water we drink and also the natural habitat that surrounds these waterways. You can see there is a real and present danger for all. The water that we drink originates from two basic sources, surface waters, such as rivers and reservoirs, and also groundwater. All our water has natural contaminants, particularly inorganic contaminants that come from the land and rock through which the water flows and there is also to a varying extent, pollution by both micro organisms and chemicals. Another older yet reasonably common way for contamination to happen is through a process called ‘back flow’. An Acton Plumber can stop back flow. So how does back-flow work? Well, normally the cold water flowing into your home is high pressure, so the filling of your bath or the watering of your garden is really quite quick but it also makes sure that your water supply is only flowing in one direction, i.e. from the hosepipe on the lawn or into your bath tub. If while watering your garden, the water pressure disappears, you may think that the hose was twisted. You lay the hose down and go and check. Whilst you are doing this, the water in your garden suddenly finds itself being drawn back into the now empty hose, and this will flow, back into the cold water mains. By law, you must fit devices to stop this ‘back flow’. In a hosepipe for example, you should fit a ‘double check’ valve on an outside tap. This is a valve that will only allow water to flow in one direction. If it is fitted and you lose pressure, it will not let water flow back into the main water supply.
