Is a backflow preventer required by code in Texas?
The Texas Commission on Environmental Quality requires all public water systems to maintain a cross-connection control program that protects the distribution system delivering drinking water to your home or business.
Are backflow prevention devices required?
The California Code of Regulations, Title 17, specifies where backflow prevention devices must be installed to protect the public drinking water systems from contamination. The District requires that commercial, industrial, irrigation, and multi-family facilities install RP devices on their potable water service lines.
Where are backflow preventers required?
Backflow preventers are placed on the main water line where the wastewater and freshwater connections meet. The device is a valve that automatically closes anytime a change in pressure occurs. Once the valve closes, sewer water can’t continue to travel in the wrong direction.
How long do backflow devices last?
How often does my backflow preventer need to be tested? Reduced Pressure Zone (RPZ) assembly needs to be tested annually and rebuilt every 5 years. Double Check Valve (DCV) assembly needs to be tested every 3 years.
What is an RPZ backflow device?
RPZ is an acronym for a reduced pressure zone. It is a type of backflow prevention device used to protect water supplies from contamination in Villa Grove, IL.
How often do backflow devices need to be tested in Texas?
annually
If there is a backflow device on your property, you must have it tested annually, regardless if you use the system or not. If you want to avoid the test, you must hire a certified plumber or backflow tester to have the sprinkler system completely removed from your property.
Do all sprinklers have a backflow preventer?
Backflow preventers are required for all irrigation systems. Landscape architects specify different types of backflow preventers based on a project’s size and potential threat for contamination of the potable water supply.

How do I know if I have a backflow prevention device?
How do I know if my property has a backflow prevention assembly? You can check to see if you have a backflow prevention assembly by looking at where water enters your property (usually in a basement by the water heater, a crawl space, or in a mechanical room).
Why do I need a backflow prevention device?
A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. Water pressure may fail or be reduced when a water main bursts, pipes freeze, or there is unexpectedly high demand on the water system (for example, when several fire hydrants are opened).
How do I know if my house has a backwater valve?
Backwater valves are usually located in the floor of your basement. If you know where to find your sump pump, the backwater valve is probably nearby. There may be a rectangular panel on top, but often the compartment itself is clear so that you can see inside relatively easily and the round cap can be removed.
How does the Austin water utility prevent backflow?
Austin Water Utility administers a backflow prevention program in conjunction with federal, state and local codes to ensure backflow prevention devices are installed and maintained where backflow may be a risk.
What do you need to know about backflow prevention?
Typically, backflow prevention assemblies are required for plumbing system connections that contain industrial fluids or chemicals, irrigation systems, fertilizers, or auxiliary water sources (including reclaimed water).
What causes a back siphonage in the water system?
Back-siphonage backflow caused by a negative pressure (i.e., a vacuum or partial vacuum) in the drinking or public water system. It can occur when water use exceeds normal delivery capacity of the water supply (e.g., a nearby fire fighting or a water main or service pipe break).
What causes a backflow in a water tank?
Backpressure backflow caused by downstream pressure that exceeds the upstream supply pressure in the drinking or public water systems due to a high pressure source. This could be caused by pumps, boilers or storage tanks.
