In water supply systems, there is usually a constant pressure to enable water to flow from your plumbing outlet, such as your shower, faucet, or hose. When that pressure fails or is reduced due to water main bursts, frozen pipes or an unexpectedly high demand for water, contaminated water from the ground can “backflow” into the system.
To prevent this from happening, it is required by law that you have a backflow prevention device installed if you have a lawn irrigation system. These devices prevent contamination of your water system from such things as pesticides, feces, fertilizers and other dangerous materials. There are over 10,000 reported cases of backflow contamination each year, and some are fatal.
It is not required that companies installing lawn irrigation systems include this backflow prevention device. Therefore, if you rely on city water and have a lawn irrigation system, you and your family may be at risk. If you need backflow prevention in Washington DC or Maryland, call ARS. Our professional Plumbing Consultants will visit your home and determine if, and what type, of backflow prevention device you need to protect your family and pets from harmful and unsanitary contaminants.
