Low-quality backflow preventers fail within 2–3 years, causing repeated parts replacement, labor, and water shutdowns – costing up to 37% more over 5 years.
Municipalities and insurers increasingly enforce strict backflow prevention codes. Non-compliant valves can result in fines or loss of operating permits.
Many suppliers promise 6–8 weeks but deliver in 12+. Unpredictable shipping costs from overseas add further budget strain.
Double check valve (DCVA) and reduced pressure zone (RPZ) models prevent backpressure and backsiphonage. Tested to ASSE 1015 / 1013 standards.
Your exact size, material (ductile iron, brass, stainless steel), end connections (flanged, threaded), and pressure class (PN10/16, Class 125/150).
