Plumbing codes require all water outlets to be equipped with a backflow prevention device to prevent contamination or pollution of the drinking water. Therefore, all sinks have a space between the end of the faucet and the flood level of the sink called an air gap.
Residential customers are only required to install a backflow preventer if the home has an in-ground irrigation system or pool. It is the customer's responsibility to notify us if an irrigation system or pool is installed. Backflow requirements vary for commercial customers based on the business's water use.

Like a backflow preventer, a check valve stops media from flowing through it in the reverse direction. Check valves, however, do not offer the degree of protection that backflow preventers do and therefore are not suitable for protecting drinking water sources.
For this reason, every commercial and industrial building is required to have a backflow prevention system, as well as multi-family residential buildings as well. However, single-family homes are typically exempt from this requirement.
When Do You Need a Backflow System? Prevention is better than cure. If you have a well or an irrigation system, you need to install a backflow device on your water system.
What is the Lifespan of a Backflow Preventer? The expected lifespan of a black flow preventer is typically 5 to 10 years, depending on the type of backflow preventer. Some common types of backflow preventers include: Double Check Valve Assemblies (DCVA)
Most residential backflow preventers are located near the water meter or the main water shut-off valve. You can also inspect external connections to locate this component. Check for any devices attached to outdoor spigots, sprinkler systems or swimming pools.
That said, most basic backflow tests range from $75 to $300. Always contact your local plumbing service to ask for an estimate and learn more about their tests to ensure you find the best deal and service.
It's also essential to note that both types of backflow preventers reduce available downstream water pressure.
Understand that it is necessary to install a backflow preventer in any situation where incoming water and wastewater have a chance of being cross-connected.
Your backflow prevention assembly should be installed inside an above-ground enclosure. It's the safest and most cost-effective place to put it. Installing your backflow preventer above ground in an outdoor enclosure allows protection for your backflow preventer and provides for easy access.
Air Gaps As Backflow Prevention Devices
An air gap is an open vertical space between the water outlet and the flood level of a fixture. It is one of the simplest and most reliable backflow prevention devices used to ensure drain water does not travel backward.

1974 - The Safe Drinking Water Act is signed into law by President Gerald Ford. Initially proposed by then President Nixon, the act gives the EPA oversight of of the nation's drinking water. This allowed the EPA to create federal regulations related to backflow with their Cross Connection Control Manual.
Much like a backwater valve, a backflow preventer will only allow water to flow in a single direction. But unlike a backwater valve, its aim is to prevent the water from leaving your system rather than entering it.
Generally, the backwater valve should be installed as close to the potential entry point of backflow as possible. This typically means installing it on the main sewer line before it enters the building. Once you have identified the location, you will need to excavate the area to access the pipe.
Most backflow prevention devices have a lifespan of 5 to 10 years, depending on the manufacturer and usage.
