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.

PR20 Pressure Limiting Valve designed to moderate and stabilize mains water pressure, which is at times too high for domestic appliances.

Industry example

An integrated detection feature continuously monitors water flow and can detect abnormal water usage which may indicate an unauthorized tap.

Vital to safeguarding potable water supply, backflow assemblies are necessary within hospitals, medical facilities, and laboratories with medical gas and water treatment systems.

ParkUSA manufactures multiple backflow preventors for use in various settings including fire department connection assemblies.

Industry sector

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.

Assemblies with one check valve can be used for other non-hazard applications, such as incorporation into fire protection systems.

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

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.

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.

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.
