Pure drinking water piped to the home or business is the result of the advanced technologies in use by today’s water purveyors.
Together, with the water purveyor, the water user has a shared responsibility to protect that purity. To assist the water user, Watts offers a wide selection of valves used to isolate the safe drinking water from hazardous contaminants.
One of the possible sources for contamination of drinking water is a connection to an irrigation system. Fertilizers, pesticides, bacteria, and other substances can be drawn into the drinking water from the irrigation system because water can be forced to return to the source of supply.
How can the drinking water be protected?
The purity of the drinking water system can be maintained by isolating it from the irrigation system. It’s simple with the correct Watts backflow prevention products.
Two conditions create backflow. The first condition is backpressure; a greater pressure originating in the irrigation system can overcome the drinking water system supply pressure causing a reverse flow condition. The second condition is backsiphonage; a suction created by the sudden loss of supply pressure, caused by water main breaks, and large demands such as fire fighting requirements.
Backpressure and backsiphonage can occur separately or together. Different Watts backflow preventers are designed to protect against one or both of these conditions.
