Zurn Wilkins 2-975XL2 2in RPZ Backflow Preventer, Lead-Free - 2-975XL2

Zurn Wilkins 2-975XL2 2in RPZ Backflow Preventer, Lead-Free - 2-975XL2

The Wilkins 2-975XL2 is a 2-inch Reduced Pressure Principle (RPZ) backflow preventer engineered for high-hazard potable water protection. Its compact wye-pattern bronze body provides short lay length and in-line service access to the checks and relief valve for faster maintenance.

Documentation and repair parts are available; recommended for commercial, irrigation, and high-hazard potable water systems requiring RPZ protection. Follow local codes for testing and installation requirements.

Features

• Lead‑free construction compliant with low‑lead plumbing laws (0.25% weighted average).
• Cast bronze body (ASTM B584) with stainless steel fasteners and Noryl seats for corrosion resistance.
• Female NPT (FNPT) x FNPT threaded ends with full-port quarter‑turn (QT) ball valves included for shutoff and service.
• 175 PSI pressure rating, 180°F temperature rating, and 350 PSI hydrostatic test rating.
• Short end‑to‑end distance (26-1/2") eases replacement and installation in constrained spaces.
• Meets ASSE 1013, AWWA C511, NSF/ANSI 61, CSA and IAPMO/CUPC listings for potable water applications.
• Wye-pattern design allows separate access to each check and the relief valve to reduce labor and repair time.

What our Experts Think

• Maximum protection RPZ design: Provides industry-leading defense against both back-siphonage and backpressure contamination in drinking water systems.
• Heavy-duty bronze construction: Built with corrosion-resistant materials for long service life in demanding environments and continuous flow applications.
• Service-friendly wye pattern body: Separate access to checks and relief valve allows faster in-line maintenance and reduced downtime.
• Lead-free potable water compliance: Meets modern low-lead plumbing regulations for safe use on municipal and building water supplies.
• Integrated shutoff flexibility: Includes FNPT connections with full-port service valves for easier installation and system isolation.
• Built for code-heavy installations: Commonly used in high-risk applications such as commercial buildings, fire systems, and irrigation tie-ins where RPZ protection is required.

Q&A

Q: What is the Zurn Wilkins 2-975XL2 used for?
A: A 2" lead-free reduced-pressure zone (RPZ) backflow preventer designed for high-hazard applications, protecting potable water systems from contamination caused by backpressure or backsiphonage.

Q: Is it safe for drinking water systems?
A: Yes. It is lead-free compliant and certified to NSF/ANSI 61 and ASSE 1013 standards for potable water protection.

Q: What level of protection does it provide?
A: High-hazard protection using a reduced-pressure zone assembly with two check valves and a relief valve that discharges when unsafe pressure conditions occur.

Q: What size and connections does it have?
A: 2-inch FNPT threaded inlet and outlet connections, designed for commercial and irrigation piping systems.

Q: What materials is it made from?
A: Lead-free cast bronze body with corrosion-resistant internal components for durability and long service life.

Q: Can it be installed in different orientations?
A: Yes. It supports horizontal or vertical installation (depending on flow direction and code requirements).

Q: What are its operating limits?
A: Typically rated up to 175 PSI working pressure and about 180°F maximum temperature.
