This blog is the second in a three-part series on the importance of well-thought-out and complete standard details for backflow prevention assemblies. In Part 1 of our series , we covered how an outdoor, above-ground backflow enclosure can save the customer money and eliminate risk.
The job of a backflow preventer is extremely important. Ideally, water coming in from the main water supply should flow in only one direction from the water supply.
However, if water pressure changes cause water to move in the other direction and back toward the main water supply, this is called backflow. A backflow preventer valve is required in all commercial buildings to protect our water supply and stop this from happening. The utility vault has been an accepted design practice for the backflow preventer installation for decades. There are a number of deaths within confined spaces like the vaults housing backflow preventer installations.
According to data collected by the U. Department of Labor :. This is an unnecessary liability for a water jurisdiction. A backflow preventer installation in an above-ground enclosure eliminates the risk. Ask anyone who has ever tested a backflow prevention device.
In fact, for safety reasons, the Las Vegas Valley Water District is in the process of removing all backflow assemblies from vaults. They also favor reduced pressure backflow preventers for the extra protection they provide. Another reason backflow preventer installations are better above ground is that they eliminate the cross-connection risk.

Because pressure is lost during these events, water is no longer being pushed forward into your home and will flow backwards into the city water lines. Backflow prevention systems are devices installed onto a pipe that only allow water to flow in one direction. A pressure vacuum backflow preventer valve is easy to configure and remove on small or large properties.
This type of valve can be installed next to an outdoor wall or inside of a recessed box below the ground. A pressure vacuum breaker is designed to prevent the dirty water in sprinkler systems from entering your sanitary water. The pressure vacuum breaker may be installed in your basement or a utility closet.
If the water from your sink or shower is discolored or cloudy, this is an indicator of a broken backflow valve in your pipes. The consumption of dirty water can cause symptoms such as nausea, diarrhea, gastrointestinal issues, stomach aches, or dehydration. Once a backflow preventer valve reaches the middle of its life cycle, it is not abnormal for a leak to form. The source of a water leak can be dirt, thermal expansion, or a change in water pressure.
If a large amount of water is being released by the backflow valve, this is a sign of damage. Even a small leak can cause negative consequences such as mold, water damage, and odors. If the water level in your bathtub is rising when you have the sink on, this is a sign of a defective backflow preventer valve. Once the backflow valve in a pipe is broken, water will become trapped and it will not circulate correctly. This issue will cause water backups that may push through other fixtures, drains, and sinks in your house.
In addition, an ineffective valve can cause slow drainage in your kitchen or bathroom sinks. If the water in your sink or shower has a weird odor, this is a sign of a malfunctioning backflow prevention device.
