UPGRADED 3/4" 720A Pressure Vacuum Breaker Assembly, Thickened Brass Backflow Preventer Valve, Back Siphon Valves for Irrigation System, Use Sealant Instead of Teflon Tape, MAX 400PSI

3/4" 720A Pressure Vacuum Breaker Assembly, Max 400 PSI Thickened Brass Backflow Preventer Valve to Maintain Plumbing System Integrity

• 𝙐𝙥𝙜𝙧𝙖𝙙𝙚𝙙 𝙎𝙚𝙖𝙡𝙞𝙣𝙜 𝙈𝙖𝙩𝙚𝙧𝙞𝙖𝙡: 720A pressure vacuum breaker uses sealant instead of Teflon tape which is prone to deterioration. The preventer backflow valve has been pressure tested and the excellent sealing ensures stability and safety of the valve in high pressure piping systems. WARNING: Unscrewing the valve will destroy the PVB seal!
• 𝙐𝙥𝙜𝙧𝙖𝙙𝙚𝙙 𝙈𝙖𝙩𝙚𝙧𝙞𝙖𝙡: 3/4" 720A pressure vacuum circuit breaker is made of thickened brass for extreme corrosion and oxidation resistance. The excellent pressure resistance of the backflow prevention valve ensures that it can withstand high pressures without cracking or breaking.
• 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.
• 𝘼𝙪𝙩𝙤𝙢𝙖𝙩𝙞𝙘 𝙑𝙖𝙘𝙪𝙪𝙢 𝘽𝙧𝙚𝙖𝙠: Sprinkler backflow preventers automatically sense changes in water pressure. If the system's water pressure suddenly drops (such as when water flow stops or pressure unexpectedly decreases), the PVB automatically opens the air inlet, allowing air to enter the system, thereby breaking the vacuum effect and preventing dirty water from flowing back.
• 𝙒𝙞𝙙𝙚 𝙍𝙖𝙣𝙜𝙚 𝙤𝙛 𝙐𝙨𝙚𝙨: Backflow preventers can be widely used in outdoor garden irrigation systems to prevent irrigation water from flowing back into the water supply system. PVB can also be used in other water systems such as cooling systems, sprinkler systems, etc. to provide multiple protections.
• 𝙀𝙖𝙨𝙮 𝙩𝙤 𝙄𝙣𝙨𝙩𝙖𝙡𝙡: The water flow direction can be seen in any installation direction of the vacuum circuit breaker, which is convenient for installation. At the same time, the included installation instructions provide detailed explanations on installation and troubleshooting.
• 𝙉𝙤 𝙒𝙤𝙧𝙧𝙞𝙚𝙨 𝘼𝙛𝙩𝙚𝙧 𝙎𝙖𝙡𝙚: We want to provide all customers with their ideal goods and are willing to put efforts on it. The carbon steel griddle is covered by a 18-month warranty. Please leave us a message if you encounter problems during use!
