Various types of backflow preventers exist for different applications and health hazard conditions, check state and other local administrative codes or other regulation on the correct backflow to use. The following backflow preventer types are available in all sizes:

OneFlow® is the environmentally-friendly way to prevent scale buildup. Through Template-Assisted Crystallization (TAC), dissolved hardness minerals in the water join together, forming microscopic crystals on the surface of the OneFlow media. Once formed, these crystals detach from the media and flow freely through the plumbing system, unable to form hard scale on internal plumbing surfaces.

Watts is part of the Watts Water Technologies family with operations in North America, Europe and Asia. Watts designs, manufactures and sells an extensive line of flow control products for the water quality, residential plumbing & heating, commercial and OEM markets.

We offer multiple system solutions from cast iron, to stainless steel, to plastic depending on your application needs. You need it. We make it. Let’s get started.

Backflow is the undesirable reversal in the flow of water from a real or potential source of contamination back to the potable (or clean) water supply. Consider having a garden hose in a bucket of soapy water at your home, and having backflow event occur causing that soapy water to "backflow" into the drinking water portion of your home. Various types of backflow preventers exist for different applications and health hazard conditions, check state and other local administrative codes or other regulation on the correct backflow to use. The most common are reduced pressure backflow preventer and double check backflow preventer valves. Backflow preventers are primarily used in sewer, wastewater, residential backflow preventer, sprinkler and irrigation backflow applications.

The term "Cross-Connection Control" is essentially is referring to backflow prevention. The definition of a Cross Connection is "A cross connection is the actual or potential connection between a non-potable substance or source." Local authorities will dictate what types of backflow preventers may not be used depending on the backflow risk and health hazard. Sewer, irrigation, wastewater and residential are the main areas. There are two types of backflow, the first is back pressure where the pressure in the downstream piping is greater than the supply pressure, this is caused by a pump or elevation of water in a high rise building, the other type of backflow is back siphonage which is caused by sub-atmospheric pressure in the water system piping.

Our extensive and established network is here to help owners do two things: monitor and improve system performance, and identify problems before they start, ensuring smooth operation.

Dual Check Valve - Model GF8080, GF8080E - The Dual Check Valve or double backflow prevention valve is basically a stripped down Double Check Valve without shut off valves and test cocks. They are non-testable and are typically used by water companies and installed after a water meter to prevent the meter from running backwards and low protection against backflow. This piece of equipment is the center of controversy with many backflow authorities and should never be confused with Double Check Valves. Check with local authorities for required installation, as most do not recognize these as backflow prevention devices.

Joseph Watts founded our company in 1874 on the belief that water boilers in textile mills shouldn’t explode. What started with a pressure relief valve in a tiny New England machine shop, has paved the way for today’s high-quality, worldwide water solution technologies. From melting ice on entire city blocks from the ground up, to filtering safe drinking water in isolated, weather disaster zones, you need water and water needs Watts.

Our dedication to providing the best products doesn’t end after we ship them. We want to ensure you have everything you need to place our products in any setting with confidence.

We combine theory with practice to design and manufacture top quality, high performance backflow prevention assemblies and flow control products. And we’re here to not only set the industry standards, but to deliver quality, performance, and affordability you demand in backflow prevention. Let’s keep things safe.

Atmospheric Vacuum Breaker - Model GFAVB - The atmospheric vacuum breaker is one of the least expensive backflow prevention assembly. The GFAVB is a non-testable unit and are good for back siphonage only for non-health hazard or health hazard conditions. They must be installed downstream from any shut off valves and cannot be under pressure for more than 12 hours. If an GFAVB is used backflow prevention on a irrigation system you must install one GFAVB after every valve for each zone in the system. It must also be installed at least 6 inches (150 mm) higher than the highest outlet in the system (some GFAVB manufacturers, and some local officials, require that they be installed 12 inches (300 mm) higher than the highest outlet). Some municipalities do not allow the use of GFAVB’s. These units will NOT prevent backflow pressure and can only protect against back siphonage.
