Watts Backflow Preventer009Repair Kit

Approval agencies, representing many diverse geographical areas and levels of government, require performance criteria regarding the function, manufacturing, installation, and testing and maintenance of backflow prevention devices and assemblies. These standards ensure the integrity of the drinking water by addressing each mechanical function, and materials of the backflow preventers *Design*. Although this testing is quite rigorous and intense our engineering team continues to be inventive in designing backflow assemblies.  Any new backflow preventer assembly that comes to market with the required approvals and listings has been thoroughly vetted and in development with Zurn Wilkins engineers for multiple years before it has come to the market.

Low-hazard application: potential backflow can pollute the drinking water.  Pollution refers to undesirable effects to the water that will not cause illness, such as discoloration, smell, or taste. The Zurn Wilkins Double Check Backflow Preventers provide low hazard protection from backsiphonage and backpressure for all water application.

Backflow is caused by pressure changes, including conditions of gravity, vacuum, or other pressure changes. There are two factors that contribute to reversal of flow in pipelines. One is backsiphonage and the other is backpressure.

Mechanical backflow prevention devices and assemblies offer the best protection against cross-connection hazards, but they are not the same. Backflow prevention assemblies consist of an inlet and outlet shut-off valve and test cocks to facilitate testing of the assembly while it is in its functional in-line position. Backflow prevention devices prevent backflow by stopping the reversal of flow and are not testable once installed because they do not have inlet and outlet shut-off valves or test cocks.

Exceptions / non-returnable items Certain types of items cannot be returned, like perishable goods, and custom products (such as special orders or personalized items). We also do not accept returns for hazardous materials, flammable liquids, or gases. Please get in touch if you have questions or concerns about your specific item. Unfortunately, we cannot accept returns on sale items or gift cards.

High-hazard application: potential backflow can contaminate the water supply. Contamination refers to any impairment to the quality of water that can result in illness. The Zurn Wilkins Reduced Pressure Principle Backflow Preventers provide high hazard protection against backsiphonage and backpressure for all water applications

You must understand the degree of hazard in your system to determine the proper solution and backflow assembly device you choose.

Before you install your next system. Here are a few common misconceptions around backflow prevention, and what you should know before you select your model.

By just looking at the last two digits of our backflow preventer model numbers you will be able to understand if this assembly is a Double Check Assembly (DC) or a Reduced Pressure Principle Assembly (RP).
