Municipal water distribution systems must be protected against potential contamination from cross-connections, such as with industrial or agricultural water sources.

Units prevent the undesirable reversal flow of water or other liquids, gases or substances into potable water distribution pipes.

2023731 — We've explored the different types of gas shut off valves, understanding their basic functions, and learning how to choose the right one for your needs.

Our backflow preventor assemblies are manufactured in a variety of models to suit almost any building site. Model types are selected based on degree of potential cross-connection hazard, varying from non-health hazard pollutants to contaminants that could causes illness or death if ingested. Double check valve assemblies are preferred and certified for contemporary use. The double valve adds security and continuously monitors water flow while detecting any abnormal or unauthorized usage. If such usage is detected, it triggers an alarm, notifying personnel or monitoring systems of potential issues.

This 1/2 inch dual check valve backflow preventer with atmospheric vent helps prevent the reverse flow of hot or cold polluted water from entering into the potable water supply. This valve is designed for continuous pressure non-health hazard applications in smaller supply lines, such as laboratory equipment, processing tanks, sterilizers, dairy equipment, and specifically for boiler feed lines. It consists of a brass body with stainless steel internal parts, integral strainer, two durable tight seating rubber check valves, and NPT female inlet and outlet connections.

Residential and commercial buildings need to protect their potable water supply and facilitate a connection to the fire department’s water supply.

Backflow prevention assemblies are often used in fire sprinkler systems to prevent backflow and ensure the integrity of the water supply dedicated to fire protection.

Backflow prevention assemblies are typically equipped with test cocks or ports for periodic testing and maintenance. The check valves can be examined to ensure they are operating properly and closing tightly to prevent backflow.

Industrial settings rely on backflow preventers to protect against potential contamination from processes, chemicals, or industrial equipment that could pose a risk to the public water supply.

In spaces with decorative or recreational water features, backflow prevention assemblies are often required to prevent stagnant or chemically treated water from entering the municipal water supply.

Backflow assemblies are commonly employed in irrigation systems to prevent the backflow of non-potable water into the main water supply.

A backflow prevention assembly contains all parts within a precast concrete vault. The components vary, depending on model, but the mechanics remain constant. Each assembly has an inlet and outlet. The inlet connects to the source of potentially contaminated water, while the outlet connects to the potable water supply system, usually a building. Water moves from the source through the inlet into the backflow assembly. Check valves are a mechanical device that allows water to flow in one direction while preventing backflow in the opposite direction.

Rigorous testing during manufacturing ensures the installation of a working system that meets quality and performance standards.

Backflow prevention assemblies stop the undesirable reversal flow of water or other liquids, gases, or substances into potable water distribution pipes. The assemblies ensure that water flows in only one direction and protects potable water systems from contamination or pollution due to backflow. Each ParkUSA BackFlo® backflow prevention assembly includes a complete cross-connection control solution for all municipal, residential, commercial, and industrial projects. The assemblies are delivered onsite and ready to plumb.

Certified backflow prevention systems contain a double check valve assembly. Check valves are mechanical, spring-loaded, or pressure sensing devices that close when there is a reversal of water flow. Under normal operation, the check valves remain open allowing water to flow without restriction. If there is a reversal in water flow and a potential of backflow, the check valve will close due. This initial closure blocks the reverse flow of water. A single check valve unit is not a certified backflow prevention system, and now rarely used to ensure cross-connection quality.
