Backflow Installation – A Necessity to Protect Your Family’s Drinking Water

Many cities require backflow installation to isolate cross connections and protect the drinking water supply. Backflow prevention devices are usually tested by an authorized inspector to confirm they are functioning correctly.Backflow Installation

Backflow can occur when there is a sudden change in water pressure from your plumbing system to the city’s water line, which can cause dirty, contaminated water to flow back into your clean drinking water. This is also known as backsiphonage. Visit to learn more.

Backflow prevention devices are a necessary part of keeping your water clean. They work like a one-way gate that allows your city’s water to flow into your home’s pipes but stops the water any time it starts flowing backward. This prevents cross-connections, which occur when the potable water supply mixes with non-potable water that can contain sewage or other contaminants. Backflow preventers also help protect your plumbing system and keep your family’s drinking water safe.

Many people wonder about the cost of installing a backflow preventer. It is important to remember that the total budget for this type of work includes a number of different costs that have nothing to do with the backflow prevention device itself. These include the permit fee, installation cost, and backflow testing cost. In addition, you must also consider the cost of a thermostatic freeze relief (if needed).

The cost of installing a backflow preventer will vary depending on your location. However, you can expect to spend less than $200 for an 8-inch backflow preventer. This cost is a small price to pay for the safety and health of your family.

In addition to protecting your water from contamination, a backflow preventer can also save you money in the long run. These devices can save you money on your utility bills by reducing the amount of energy used by your appliances. This will help to reduce your carbon footprint and protect the environment.

It is important to remember that you must get your backflow preventer tested every year. Failure to do so may result in a fine. Moreover, you may even be required to shut off your water. Therefore, it is a good idea to contact 770BACKFLOW to perform the test.

Installing a backflow preventer is a relatively simple task, and it can be completed quickly. Unlike most building jobs, this job does not require a lot of effort or disruption. Moreover, it is usually completed in a few hours and only requires momentarily turning off your water supply. If you are worried about the cost of this service, you can always talk to a local plumber for a quote.


There are several types of backflow preventers, each with its own set of features. The type you need depends on the circumstances surrounding your backflow prevention system installation. For instance, a new installation will require you to choose a backflow assembly that meets code requirements, while replacing an existing assembly may require you to select another model. You should also consider the size of your facility and its water needs when choosing a backflow preventer assembly.

The most common backflow preventers are atmospheric vacuum breaker assemblies, double check valve assemblies, and reduced pressure zone assemblies (RPZ). A RPZ is the most complex and expensive backflow device. However, it is the most secure and reliable when working properly. It consists of an inlet shutoff valve, two independently operating spring-loaded check valves separated by a pressure differential relief valve, and four test cocks.

Backflow prevention systems protect buildings and their occupants from the contaminated water that can result from back-pressure siphonage or back-pressure surges. These contaminants can include fecal matter, which has been responsible for the spread of diseases such as dysentery and typhoid. Other dangerous bacteria, such as E coli and Shigella, can also be found in backflow.

To keep these pathogens from entering the public supply line, it is important to maintain backflow preventers in good condition. Backflow prevention systems must be able to detect changes in water pressure and work automatically to correct them. However, a change in pressure may not be obvious, especially if it is localized or only affects one fixture or area of the building. Conventional pressure-monitoring equipment may not pick up these types of incidents, so they go undetected.

In addition to detecting backflow, backflow preventers should be resistant to particulate. This is important because particles such as dirt, sand, and gravel can lodge into the critical sealing areas of backflow preventers and cause them to fail or become inoperable. To reduce the risk of this, a strainer should be installed in all backflow prevention systems.

Many piping systems are considered critical services, meaning that they cannot be interrupted even for short periods of time. In these cases, parallel backflow preventers can be installed to ensure that there is always a backup in place when the primary preventer needs service or maintenance. Often, this is required for hospitals and other high-risk facilities.


Backflow prevention is vital to the health of your home or business. It prevents dirty water from intermingling with clean water lines and polluting the supply. This type of pollution can happen when there is a dramatic change in water pressure. It can also occur if you have cross-connections between potable and non-potable water systems, such as in a dishwasher or reverse osmosis system. Backflow prevention devices are a necessary safety measure for any property owner, and they must be properly installed and tested to ensure that they work correctly. Backflow testing is required by most municipalities, and failure to test could result in a fine or even the loss of your water supply.

The installation process can be complex and requires professional help. A backflow preventer should be placed in a location that is easy to access for inspection, maintenance and repair. It should also be protected from tampering and harsh environmental conditions. A backflow preventer can be placed in a secure protective enclosure or on the ground near your plumbing system. In some cases, you may be able to get by with an air gap, which is just open space between your backflow preventer and any point where dirty water can collect or pool.

Once the device is installed, you will need to test it on an annual basis. It is important to schedule the tests early in order to avoid any delays or problems with your water supply. A licensed plumber should perform the test, and they will be able to identify any potential issues with your backflow prevention device.

When installing your backflow preventer, make sure that it is positioned properly in your piping system. You will need to install braces or brackets to keep the backflow preventer in place, and you will need to use the right fittings for each connection. Use a wrench to tighten each connection securely, and be sure to use pipe tape to ensure a leak-proof seal.

If you are replacing a backflow prevention device, you will need to apply for a permit before starting the project. The permit will specify the type of assembly that you need and the date of your last test. The backflow prevention device must be tested before it can be reinstalled in your piping system.


Backflow testing is a critical part of any backflow prevention system. It assesses the pressure levels in your building’s plumbing to ensure that untreated and contaminated water cannot be “back-siphoned” into city water lines. Backflow tests are required by law for certain properties and businesses, and failing to keep up with them can result in fines or the termination of water service.

The test involves closing valves and checking for changes in gauge movement, water leaks and other clear signs that backflow is present. It is done by a licensed backflow tester, and the results of the test must be filed with the Department of Environmental Protection.

Testing is done for residential, commercial and industrial backflow preventers. It can be complicated, as each type of device has different requirements and testing methodologies. Argent Plumbing can help you determine which type of backflow preventer will work best for your property, and help you with the process of installation and testing.

In addition to assessing backflow, backflow testing can also detect cross-connections and contamination risks. These include bacterial contaminants like Shigella and E coli, which cause diarrhea and gastroenteritis. These bacteria can be found in many sources of water, including city water.

A backflow preventer is a valuable investment that helps to protect the quality of your city’s drinking water. However, having your backflow preventer inspected and tested regularly by a certified technician is essential. Backflow preventers are complex, with many moving parts and seals that can wear down over time. Without proper maintenance, a backflow preventer can fail, causing contaminants to enter the city’s drinking water supply.
