More features

• 【UPC & ASSE 1020-2020 Certified Protection】 This 1" pressure vacuum breaker assembly is certified to Uniform Plumbing Code and ASSE 1020-2020 standards, providing code-recognized backflow protection for irrigation, sprinkler, and outdoor water systems.
• 【Better Sealing Materials】 The 1" backflow prevention valve uses a high-sealing sealant, which is not only not easy to age, but also can maintain a good sealing effect even under high pressure, which is better than waterproof tape. WARNING: Loosening the valve connections will damage the PVB seal!
• 【Heavy-duty Valve Body & Cover】 The anti-siphon valve has upgraded materials in all aspects. The thickened brass valve body and metal top cover are specially designed for corrosion resistance, pressure resistance and long-term outdoor use.
• 【Wide Range of Use】 Backflow preventers can be widely used in outdoor garden irrigation systems, cooling systems, sprinkler systems, etc., providing multiple protections to prevent irrigation water from flowing back into the water supply system.
• 【Reliable Performance】 Backflow prevention valves play an important role in anti-siphoning in residential and commercial plumbing systems. Vacuum breakers protect the water supply by effectively preventing the backflow of unclean water back to the clean water source.
• 【No Worries After Sale】 We want to provide all customers with their ideal goods and are willing to put effort into it. The PVB is covered by a 60-month warranty. Please leave us a message if you encounter problems during use!
