flow of non potable water or other undesirable substances through a cross connection into the consumer\u2019s or public potable water.<\/span><\/p>\n<p><strong>Why Protect Against Backflow?<\/strong><\/p>\n<p><span>Backflow can contaminate the water system, making it unsafe to drink.<\/span><\/p>\n<p>Each water supplier is required to ensure that their product is safe to use, to the best of their ability.<\/p>\n<p>Consumers assume that the water being supplied to them is safe and it is the responsibility of water suppliers to make sure that it is.<\/p>\n<p><strong>What Is A Backflow Preventer?<\/strong><\/p>\n<p>As its name implies, a <strong>backflow preventer<\/strong> is a device used to ensure that unpotable water does not contaminate potable water.<\/p>\n<p>There are many types of backflow preventers such as the double check valve assembly, pressure vacuum breaker assembly, and the reduced pressure principle assembly.<\/p>\n<p>The residential double check valve is another example of a mechanical backflow preventer.<\/p>\n<table style=\"width: 100%;\" border=\"0\">\n<tbody>\n<tr>\n<td><img loading=\"lazy\"

stuff\u201d poured from some faucets in the Town of Woodsboro, Maryland. Town personnel notified the County Health Department and the State Water Supply Division. The State dispatched personnel to take water samples for analysis and placed a ban on drinking the Town\u2019s water. Firefighters warned residents not to use the water for drinking, cooking, bathing, or any other purpose except flushing toilets. The Town began flushing its water system. An investigation revealed that the powerful agricultural herbicide Paraquat had backflowed into the Town\u2019s water system.<\/p>\n<p>Someone left open a gate valve between an agricultural herbicide holding tank and the Town\u2019s water system and, thus, created a cross-connection. Coincidentally, water pressure in the Town temporarily decreased due to failure of a pump in the Town\u2019s water system. The herbicide Paraquat was backsiphoned into the Town\u2019s water system. Upon restoration of pressure in the Town\u2019s water system, Paraquat flowed throughout much of the Town\u2019s water system.<\/p>\n<p>Fortunately, this incident did not cause any serious illness or death. The incident did, however, create an expensive burden on the Town. Tanker trucks were used temporarily to provide potable water, and the Town flushed and sampled its water system extensively.<\/p>\n<div>\n<p>DATE OF BACKFLOW INCIDENT: December 1987<br \/>\nLOCATION OF BACKFLOW INCIDENT: Spokane, Washington<br \/>\nSOURCE(S) OF INFORMATION:<br \/>\n&#8211; Pacific Northwest Section of the American Water Works Association, Summary of Backflow Incidents, Fourth Edition, 1995<\/p>\n<p align=\"center\">CASE HISTORY<\/p>\n<p>On December 31, 1987, the Spokane, Washington, Water Department received complaints about air in the water and dispatched crews to the scene to flush the water mains. Upon investigation, the City Water Department discovered that a compressor at a soft drink bottling plant had injected air into the public water system.<\/p>\n<p>Personnel at the bottling plant said that a potable water line into a shop area froze often during winter and that they used compressed air to clear the line. Workers normally closed isolating valves before attempting to clear the line, but they forgot to close the valves this time. Consequently, a large amount of air was injected into the public water system surrounding the bottling plant.<\/p>\n<p>The Water Department required the installation of a reduced-pressure principle backflow-prevention assembly at the bottling plant to prevent recurrence of the problem.<\/p>\n<p>\u00a0<\/p>\n<p>DATE OF BACKFLOW INCIDENT: March 1988<br \/>\nLOCATION OF BACKFLOW INCIDENT: Eugene, Oregon<br \/>\nSOURCE(S) OF INFORMATION:<br \/>\n&#8211; Pacific Northwest Section of the American Water Works Association, Summary of Backflow Incidents, Fourth Edition, 1995<\/p>\n<p align=\"center\">CASE HISTORY<\/p>\n<p>On March 31, 1988, superheated water from a boiler in a tire retreading plant in Eugene, Oregon, backflowed into the plant\u2019s potable water system. The hot water, which contained an unidentified boiler treatment compound, broke (i.e., melted) the two-inch-diameter PVC water service pipe to the plant and damaged the City\u2019s water main.<\/p>\n<p>An unapproved backflow device consisting of two single check valves was installed in the potable water feed line to the boiler at the tire retreading plant. Both check valves failed. There was no backflow preventer at the service connection to the plant.<\/p>\n<p>The water utility ordered the immediate installation of a reduced-pressure principle backflow-prevention assembly at the water service connection to the tire retreading plant.<\/p>\n<p>\u00a0<\/p>\n<p>DATE OF BACKFLOW INCIDENT: November 1976<br \/>\nLOCATION OF BACKFLOW INCIDENT: Wenatchee, Washington<br \/>\nSOURCE(S) OF INFORMATION:<br \/>\n&#8211; American Water Works Association, Opflow, May 1977<br \/>\n&#8211; Pacific Northwest Section of the American Water Works Association, Summary of Backflow Incidents, Fourth Edition, 1995<\/p>\n<p align=\"center\">CASE HISTORY<\/p>\n<p>In November 1976, approximately 300 gallons of liquid containing 1.2 pounds of the pesticide Endrin was backsiphoned from a pesticide applicator\u2019s truck into a small public water system serving 21 residents near Wenatchee, Washington. Endrin is a very toxic chlorinated hydrocarbon applied to orchards in late fall to control mice.<\/p>\n<p>This incident occurred when, by coincidence, three applicators were filling their trucks from three separate hydrants on a water main connecting the public water system\u2019s well to a storage tank. The storage tank was about \u00ab mile away from, and about 200 feet above, the well. The withdrawal of water to fill two trucks at the lower end of the water main (near the well) created a negative pressure in the higher end of the water main (near the storage tank), and the contents of the truck at the higher end of the water main were backsiphoned into the public water system.<\/p>\n<p>The public water system did not employ a full-time operator. Consequently, the contamination problem went undetected and unreported until two days after the incident. During that time, several families drank, and bathed in, the contaminated water. Fortunately, the chemical was greatly diluted in its passage through the storage tank, and therefore, no illnesses were reported.<\/p>\n<p>When the State was notified of the contamination problem, it ordered the public water system to shut down, advised consumers of the situation, and initiated a sampling program. Initial samples showed 130 parts per billion of Endrin in the water. The system drained and scrubbed its storage tank and flushed<\/p>\n<p>\u00a0<\/p>\n<p>DATE OF BACKFLOW INCIDENT: January 1981<br \/>\nLOCATION OF BACKFLOW INCIDENT: Norfolk, Virginia<br \/>\nSOURCE(S) OF INFORMATION:<br \/>\n&#8211; Pacific Northwest Section of the American Water Works Association, Summary of Backflow Incidents, Fourth Edition, 1995<br \/>\n&#8211; U.S. Environmental Protection Agency, Cross-Connection Control Manual, 1989<br \/>\n&#8211; Watts Industries, Inc.; Watts Regulator News\/Stop Backflow<\/p>\n<p align=\"center\">CASE HISTORY<\/p>\n<p>On January 29, 1981, a nationally known fast food restaurant in the City of Norfolk, Virginia, complained to the City Water Department that all their drinks were being rejected by customers because the drinks tasted salty. The City Water Department inspected all potable water lines at the restaurant for cross-connections but found none. Then the City Water Department checked with adjacent customers and received another salty water complaint from a shipyard. The same water main lateral served both the restaurant and the shipyard. City Water Department personnel promptly conducted an inspection of the shipyard and discovered that sea water had backflowed into the City\u2019s public water system.<\/p>\n<p>The shipyard had a high-pressure fire protection system supplied by sea water. The sea water was delivered by both electric and diesel pumps, which were primed by using a potable water line connected directly to the high-pressure fire protection system. Workers left this priming line open. Thus, while the electric pumps were trying to maintain high pressure in the fire protection system, they were pumping sea water back through the priming line and into the City\u2019s public water system. A backflow preventer had been previously installed at the water service connection to the shipyard. However, the backflow preventer froze and burst earlier in the winter and was removed and replaced with a spool piece to maintain potable water service to the shipyard.<\/p>\n<p>To correct the problem, the potable water priming line to the fire protection system pumps was removed. Also, a new backflow preventer was installed at the water service connection to the shipyard. Heat tape was wrapped around the new backflow preventer to prevent freezing of the backflow preventer.<\/p>\n<p>\u00a0<\/p>\n<p>DATE OF BACKFLOW INCIDENT: May 1979<br \/>\nLOCATION OF BACKFLOW INCIDENT: Winnepeg, Manitoba, Canada<br \/>\nSOURCE(S) OF INFORMATION:<br \/>\n&#8211; American Water Works Association, Recommended Practice for Backflow Prevention and Cross-Connection Control, AWWA Manual M14, Second Edition, 1990<\/p>\n<p align=\"center\">CASE HISTORY<\/p>\n<p>On May 25, 1979, personnel at a local refinery in Winnepeg, Manitoba, called the City because the drinking water at the refinery had an oily, gasoline-type odor.

It was determined that a backflow had occurred in the refinery\u2019s laboratory.<\/p>\n<p>\u00a0<\/p>\n<p>DATE OF BACKFLOW INCIDENT: September 1996<br \/>\nLOCATION OF BACKFLOW INCIDENT: Hillsborough County, Florida<br \/>\nSOURCE(S) OF INFORMATION:<br \/>\n&#8211; Hillsborough County Water Department<\/p>\n<p align=\"center\">CASE HISTORY<\/p>\n<p>On September 18, 1996, a meter reader with the Hillsborough County Water Department noticed that the water meter at a home in northwest Hillsborough County was registering backwards. A cross-connection had been created between the potable and reclaimed water systems at this premises, and reclaimed water was backflowing into the public potable water system.<\/p>\n<p>Apparently, the County\u2019s reclaimed water service connection to this residential premises had recently been hooked up to an existing irrigation system at the premises. The irrigation system, which was previously supplied with water from the home\u2019s potable water system, was not disconnected from the home\u2019s potable water system. Furthermore, a backflow preventer was not installed at the County\u2019s potable water service connection to the premises. The County Water Department estimated that about 50,000 gallons of reclaimed water backflowed into the public potable water system.<\/p>\n<p>After discovering the cross-connection, County Water Department personnel immediately shut off reclaimed water service to the residential premises where the cross-connection was found and notified the County Health Department of the cross-connection. County Water Department personnel then began flushing potable water mains in the area and advised the owner of the premises where the cross-connection was found to flush all water outlets at the premises. Based upon analysis of water samples collected by its Environmental Laboratory staff, the County Water Department reckoned that the cross-connection\u2019s impact was limited to that portion of the public potable water system within 1,000 feet of the cross-connection.<\/p>\n<p>On September 19, the owner of the residential premises where the cross-connection was found hired a plumber to eliminate the cross-connection.<\/p>\n<div>\n<p>DATE OF BACKFLOW INCIDENT: December 1983<br \/>\nLOCATION OF BACKFLOW INCIDENT: San Antonio, Texas<br \/>\nSOURCE(S) OF INFORMATION:<br \/>\n&#8211; American Water Works Association, Recommended Practice for Backflow Prevention and Cross-Connection Control, AWWA Manual M14, Second Edition, 1990<\/p>\n<p align=\"center\">CASE HISTORY<\/p>\n<p>In December 1983, effluent from a wastewater treatment plant in San Antonio, Texas, backflowed into the potable water system at the plant because of maintenance activities.<\/p>\n<p>Eight employees reportedly suffered gastrointestinal problems.

They shall be installed in agreement with and under the supervision of the supplier of water or his designated representative (plumbing inspector, etc.) at the consumer\u2019s meter, at the property line of the consumer when a meter is not used, or at a location designated by the supplier of water or the Department. The devices are:<\/p>\n<p>(a) Air gap separation \u2013 A physical separation between the free-flowing discharge end of a potable water supply pipeline and an open or non-pressure receiving vessel. An \u201capproved airgap separation\u201d shall be at least double the diameter of the supply pipe measured vertically above the top of the rim of the vessel. In no case shall it be less than 1 inch.<\/p>\n<p>(b) Reduced pressure backflow preventer \u2013 A device containing within its structure a minimum of two independently acting approved check valves, together with an automatically operating pressure differential relief valve located between the two check valves. The first check valve reduces the supply pressure a predetermined amount so that during normal flow and at cessation of normal flow the pressure between the checks shall be less than the supply pressure. In case of leakage of either check valve, the differential relief valve, by discharging to the atmosphere, shall operate to maintain the pressure between the checks less than the supply pressure. The unit shall include tightly closing shutoff valves located at each end of the device, and each device shall be fitted with properly located test cocks.<\/p>\n<p>(c) Atmospheric vacuum breaker \u2013 A backflow prevention device which is operated by atmospheric pressure in combination with the force of gravity. The unit is designed to work on a vertical plane only. The one moving part consists of a poppet valve which must be carefully sized to slide in a guided chamber and effectively shut off the reverse flow water when a negative pressure exists.<\/p>\n<p>(d) Pressure vacuum breaker \u2013 A pressure vacuum breaker is similar to an atmospheric vacuum breaker except that the checking unit \u201cpoppet valve\u201d is activated by a spring. This type of vacuum breaker does not require a negative pressure to react and can be used on a pressure side of a valve.<\/p>\n<p>(e) Double check valve assembly \u2013 An assembly composed of two single, independently acting, check valves, including tightly closing shutoff valves located at each end of the assembly and suitable connections for testing the water tightness of each check valve. A check valve is a valve that is drip-tight in the normal direction of flow when the inlet pressure is one psi and the outlet pressure is zero. The check valve shall permit no leakage in a direction reverse to the normal flow. The closure element (e.g. clapper) shall be internally weighted or otherwise internally loaded to promote rapid and positive closure.<\/p>\n<p>(f) Residential Dual Check \u2013 A compact unit manufactured with two independent spring actuated check valves.
