• 3/4" 975XL reduced pressure principle backflow preventer delivers industry-leading water line safety with a triple-defense structure combining dual check valves and an intermediate pressure relief chamber. It blocks both backpressure and siphon backflow effectively. Visible dripping from the relief drain alerts you to internal leaks early to prevent reverse water flow into municipal main lines.
• Compact Y-shaped body comes with separate top access covers for each internal component. You can replace gaskets, valve seats and relief parts without detaching the entire valve from pipes to cut maintenance time. Built with three test cocks for annual pressure testing and integrated shut-off ball valves for quick water cutoff, compatible with both horizontal and vertical mounting.
• Heavy-duty cast bronze body, silicone diaphragms and stainless steel fasteners deliver excellent corrosion resistance for outdoor irrigation systems. The built-in relief chamber eases water hammer damage and slows seal aging. Replace only worn spare parts via standard repair kits to cut long-term operation costs of your 3/4 backflow preventer.
• 3/4" FNPT female thread design connects seamlessly with most common plumbing pipes. It holds a maximum working pressure of 175 PSI and works steadily between 33℉ and 140℉. The streamlined compact body easily fits confined valve pits, great for new pipeline builds and existing pipe upgrades while maintaining steady water flow.
• This 975XL style reduced pressure principle backflow preventer works with a wide range of water supply systems. Perfect for home yard sprinklers, commercial lawn irrigation, greenhouse nutrient watering, ponds, fountains, hotel swimming pools and car washing machines.
