ASSE Standard 1024-2017: Dual Check Backflow Preventers

Water splashing on hands represents the dual check backflow that is set by ASSE Standard 1024-2017

The body needs water to function. Think about all the water that flows through one’s system on a daily basis. It’s a lot. Water makes up about 60 percent of a person’s body weight and is the primary chemical component in the human body. It’s no wonder water safety is a significant health matter that must be treated seriously. Backflow takes place when water reverses in a system, causing once potable water to become contaminated. One of the most common safeguards against this problem are a dual check backflow preventers. ASSE Standard 1024-2017: Performance Requirements for Dual Check Backflow Preventers offer guidelines for these mechanisms.

In 1933, during the World’s Fair in Chicago, a plumbing system famously caused a backflow incident to occur. This backflow problem led to 1,409 people coming down with amoebic dysentery. 98 people died from it. Since then, backflow incidents have remained a problem throughout the US.

ASSE Standard 1024-2017 relates directly to devices considered to be dual check backflow preventers. A dual check backflow preventer is an apparatus used to keep water potable. It has two independently acting check valves. This device is designed to keep polluted or contaminated water from coming back into a water source one might use.

ASME Standard 1024-2017 looks at many different areas of the dual check backflow preventers. For example, it discusses size range, pressure range, temperature range, and flow capacity.

ASSE Standard 1024-2017: Performance Requirements for Dual Check Backflow Preventers is available at the ANSI Webstore.
