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

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.

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.

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.

Maid O' Mist manufactures and markets automatic and manual air elimination valves for hydronic, steam and solar applications. We also manufacture and market a line of float operated level controls for water applications.

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

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.

Correct problems and avoid trouble by installing these float-operated Auto-Vents. They vent air from mains, solar panels, pipe lines, boilers, unit heaters, chillers, convectors, radiant panels, coils, baseboard and free-standing radiation.

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

The No. 27 and 37 Auto-Vents® are dependable float-operated valves. Their construction and internal working parts are the same as the No. 7 Series Auto-Vents® except smaller in size. Made of non-ferrous metals.

ParkUSA designed and manufactured a custom DeconTank® for this Washington hospital’s new campus. The state-of-the-art system integrates a fiberglass holding tank, diverter, and control system to manage hazardous wastewater efficiently.

The No. 7 Series Auto-Vents air eliminators are made of brass and equipped with a self-closing, float-operated valve. The valve is equipped with a Monel metal spring and a Neoprene® valve seat which is unaffected by high temperatures, oil and anti-freeze. No air chamber is required. The vent is regularly fitted with a patented cap that may be used as a check in case of a leak caused by core sand or scale.

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.

The LintTrooper® Model LTDB 2500 helps Portland Rent All enhance wastewater management for their expanding hospitality services. This system ensures compliance with Portland’s pH and solids standards through advanced filtration, pH monitoring, and IoT-based real-time control.

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