b'BACKFLOW PREVENTION FEATURESBackflow prevention devices are designed to protect the public water supply Various Models for Different from cross-connections. A modern community water supply system is designed Applications Availableto ensure that water flows to properties and buildings under pressure. Completely Pre-assembledThis community water network contains many users where there is a risk for Easy Installationto public health if there is a cross-connection between the water supply and Easy Maintenancea contaminated source. A cross-connection can occur where there is a pressurePrecast Concrete Containment drop in the water main. This pressure drop causes a vacuum and siphons ofVault Constructionentrainment water from end-users into the public water supply.Long-Lasting and Dependable Public water system pressure can be affected when: Service there is a break in the water main.Only Certified Equipment Usedwater is being pumped from the main water supply during a fire.for Construction a customer is using water at a higher pressure than the pressure supplied.heavy water use downstream reduces water pressure upstream.Codes and jurisdictions require the water outlet at the property is higher than the water main, causing constanta backflow preventer device back pressure.when certain types of hazards exist, including contamination of public water supply from a BACKFLO MODELS water user, this issue is known as cross-connection. Cross-connection hazards are found in potable, fire-protection, irrigation, and industrial water lines.Single dector check Backflow preventorDouble detector check preventorDouble Detector Check Backflow Reduced Pressure Backflow PreventerRPZ with cage24'
