Lawn irrigation systems can backflow contaminated water into your drinking water. In order to prevent this, building codes require that these systems be protected with a backflow preventer: International Plumbing Code 2006 608.16.
A few potential areas include irrigation systems and areas where the plumbing system connects to municipal water lines. 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.
Contaminants would make their way into the H2O, making it undrinkable. Contaminated drinking water may have more consequences than you think. Without backflow preventers to prevent contaminants from entering drinking water, people would suffer from increased heart rates and trouble breathing.
Manual Drain Method- This method is used when there are manual valves located at the end and low points of the irrigation piping. This systems are drained by shutting off the irrigation supply (usually a stop and waste or a valve in the basement), and opening the manual drain valves.

You can tackle blowing out the system yourself using a typical homeowner-grade air compressor (you need at least 40-50 PSI) or hire this task out to an irrigation specialist. Many irrigation companies run winterizing specials in the fall that include a general inspection of the system.
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.
Backflow preventer installation costs between $135 and $1,100 (or more if extensive labor is required). On average, you'll pay $350 to install a backflow preventer. The complexity of your home's layout and the exact device your plumbing system needs could drive up the costs.
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.
Backflow prevention devices must be installed on all sprinkler systems (including sprinklers attached to hoses) using potable (fit for drinking) water. Backflow prevention devices are designed to prevent contamination of the potable water system from pesticides, feces and other hazardous materials.
Plumbing codes require all water outlets to be equipped with a backflow prevention device to prevent contamination or pollution of the drinking water.
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.
A typical price for a Backflow Preventer & Vacuum Breaker is $180 but can range from approximately $7 to $2,583.
While vacuum breakers are a type of backflow preventer, these are often installed on older hose bibs whereas newer hose bibs typically have backflow preventers built into the bib. This can often be identified by a small hole in the stem of the hose bib handle.
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.
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)
Backflow preventers for sprinkler or sewer systems cost $100 to $600 for the device alone. These systems are bigger and more complicated than a hose, so their backflow preventers are larger and use multiple valves. Your installer will have to install these preventers on your main water line or sewer pipe.
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.
According to homeadvisor, on average, homeowners pay between $135 and $1,000. The backflow prevention device can range from $35 to $600, labor fee could cost between $100 and $400. While backwater or check valve including installation, costs range between $70 and $250.
Look For The Main Water Line:
If there are two outlets for your house (one for upstairs and one for downstairs), you have a backflow preventer. If the main outlet is only one, it may still be a good idea to check and make sure because some states don't require backflow devices.
The water in the sprinkler pipes freezes and expands, damaging your underground system. As water freezes at 32 degrees Fahrenheit, a sprinkler system will freeze.
The national average cost of sprinkler winterization is $90, with most sprinkler systems costing $60 to $120 to winterize. However, homeowners with large yards that contain many watering zones may pay as much as $275. Conversely, homeowners with tiny systems may pay as little as $45.
The valve itself is usually a few feet from where the main pipe comes in from outside. If you have a sprinkler system, you may have a second shut-off valve connected to that system supplied from a different external water line. The sprinkler system may also have more than one valve.
