About ZURN WILKINS

Zurn Wilkins is a product line within the Zurn Water Solutions portfolio, historically associated with the Wilkins Regulator Company, a manufacturer of backflow prevention and water control valves. The brand's catalog centers on mechanical devices that protect potable water systems from contamination and regulate water pressure in commercial, institutional, and industrial plumbing. 3G Electric supplies Zurn Wilkins backflow preventers, pressure regulators, and vacuum breakers to buyers specifying or replacing components in water distribution and process piping.

The product families most commonly sourced through 3G Electric include hose bibb vacuum breakers, pressure vacuum breakers, and reduced pressure zone assemblies. Hose bibb vacuum breakers, such as the BFP-8F and BFP-9, are brass-bodied units with male and female garden hose thread connections. They provide back-siphonage protection for low health hazard applications and are rated for water media up to 180°F. These units carry ASSE 1011 listing and include a set screw for tamper resistance. Pressure vacuum breakers, including the 34-710, 1-710, 114-720A, 34-460XL, 1-720AU, and 34-420XL, use FNPT x FNPT connections and are intended for high health hazard applications. Depending on the model, they operate within temperature ranges from 33°F to 140°F or up to 180°F, and several are lead-free constructions. These devices prevent back-siphonage in piping systems where a vacuum condition could draw non-potable water into the potable supply.

Technical buyers selecting Zurn Wilkins products typically evaluate connection type, temperature rating, health hazard classification, and lead-free compliance. The line includes both rough brass and lead-free options to meet different regulatory and application requirements. Pressure ratings, flow capacities, and specific end connections vary by model, so specifiers should confirm the exact manufacturer part number against the system design. Many Zurn Wilkins backflow preventers are repairable, with replacement parts available for seats, discs, and check assemblies, which supports maintenance programs in facilities where continuous operation is required.

3G Electric supports the Zurn Wilkins line by stocking a range of backflow prevention and water control products and providing quotation and order fulfillment for buyers worldwide. The company serves plant engineers, maintenance managers, and procurement specialists who need to identify and obtain specific Zurn Wilkins models for new installations, replacements, or spares. Because the product line includes numerous part numbers with subtle differences in connection size, temperature rating, and hazard classification, 3G Electric's role is to help buyers match the correct catalog item to the application. Orders can be placed for individual units or larger quantities, and the company ships globally from its distribution network.

Common Applications

  • Commercial irrigation systems — Zurn Wilkins pressure vacuum breakers (e.g., 34-710, 1-710) prevent back-siphonage from sprinkler lines into potable water.
  • Industrial process water — Lead-free pressure vacuum breakers (e.g., 34-460XL) protect potable supplies where high health hazard conditions exist.
  • Institutional plumbing — Hose bibb vacuum breakers (e.g., BFP-8F, BFP-9) provide low hazard protection on janitorial and maintenance hose outlets.
  • Food and beverage plants — Zurn Wilkins pressure vacuum breakers (e.g., 114-720A) isolate potable water from cleaning and process lines.
  • HVAC and boiler feed — Pressure vacuum breakers (e.g., 1-720AU) prevent contamination of potable water used for makeup or auxiliary systems.
  • Municipal water distribution — Zurn Wilkins backflow preventers (e.g., 34-420XL) are installed at service connections to protect the public supply.

Frequently asked questions

Common questions about ZURN WILKINS from 3G Electric.

What is the difference between a Zurn Wilkins hose bibb vacuum breaker and a pressure vacuum breaker?

Hose bibb vacuum breakers, such as the BFP-8F and BFP-9, are small brass units that attach to a threaded hose connection. They provide back-siphonage protection for low health hazard applications and are rated up to 180°F with ASSE 1011 listing. Pressure vacuum breakers, such as the 34-710 or 1-710, are installed in piping systems with FNPT connections and are designed for high health hazard applications. They operate within specific temperature ranges (33°F to 140°F or up to 180°F depending on model) and protect against both back-siphonage and back-pressure. Selection depends on the hazard level, connection size, and system temperature.

Are Zurn Wilkins pressure vacuum breakers lead-free?

Several Zurn Wilkins pressure vacuum breaker models are lead-free, including the 114-720A, 34-460XL, 1-720AU, and 34-420XL. These are identified as lead-free in the product description and are suitable for potable water applications where lead content is regulated. Other models, such as the 34-710 and 1-710, may not be designated lead-free. Buyers should verify the specific model's compliance with local lead-free requirements before ordering. 3G Electric lists lead-free status in the product specifications for each Zurn Wilkins item.

What temperature range do Zurn Wilkins pressure vacuum breakers support?

Zurn Wilkins pressure vacuum breakers are available with different temperature ratings. Models such as the 34-710 and 1-710 operate from 33°F to 140°F. The 114-720A and 1-720AU operate from 33°F to 110°F. The 34-460XL is rated up to 180°F. The 34-420XL is rated for 140°F. These ratings apply to water media and should not be exceeded. When selecting a model, confirm the maximum and minimum operating temperatures against the actual system conditions, including any potential for freezing or elevated process water temperatures.

What does ASSE 1011 mean for Zurn Wilkins hose bibb vacuum breakers?

ASSE 1011 is a product standard for hose connection vacuum breakers. Zurn Wilkins hose bibb vacuum breakers, such as the BFP-8F and BFP-9, are listed to this standard. The listing indicates the device has been tested and certified to meet specific performance requirements for back-siphonage protection when installed on a hose bibb or threaded outlet. It covers low health hazard applications only. For high health hazard applications, a pressure vacuum breaker or reduced pressure zone assembly is typically required. The ASSE 1011 listing is a common specification requirement for hose bibb vacuum breakers in commercial and institutional plumbing.

Can Zurn Wilkins backflow preventers be repaired or do they need to be replaced?

Many Zurn Wilkins backflow preventers are designed to be repairable. Replacement parts such as check assemblies, seats, discs, and springs are available for common models. Repair is often preferred in maintenance programs because it extends the service life of the valve body and can be more cost-effective than replacing the entire unit. However, repair feasibility depends on the specific model and the condition of the body and internal components. 3G Electric can supply both complete Zurn Wilkins units and replacement parts; buyers should provide the model number and serial number when requesting repair parts to ensure compatibility.

What connection types are available on Zurn Wilkins pressure vacuum breakers?

Zurn Wilkins pressure vacuum breakers commonly use FNPT (female national pipe thread) connections on both inlet and outlet. Models such as the 34-710, 1-710, 114-720A, 34-460XL, 1-720AU, and 34-420XL all feature FNPT x FNPT connections. Hose bibb vacuum breakers use garden hose thread (GHT) connections, with male and female configurations. Connection size varies by model and is typically indicated in the part number or product specifications. When ordering, confirm the pipe size and thread type required for the installation to avoid mismatches.
