A backflow preventer designed for a residential irrigation system costs $350. The average cost of installing the backflow preventer for an irrigation system is $250.

Next up, we have the backflow preventers that are meant to be used together with appliances and pieces of equipment. These are larger than the first type of backflow preventer we detailed above. Backflow preventers that are designed to be paired with appliances cost an average of $55.
These items stop the improper flow of water inside hoses. The difference this time is that those hoses are connected to appliances or pieces of equipment around your home.

Backflow Preventer for Irrigation Systems

You’ll notice that these backflow preventers feature a more complex design. That sophisticated design allows them to effectively stop the incorrect flow of water into your home.
Installing backflow preventers designed for irrigation systems must also be done by professionals. Since these fixtures often have to be installed on sewer pipes, you cannot mess around with them.

The fixtures meant for appliances are trickier to work with. Consider hiring a professional to install them. They will usually charge $150 for that service.
Backflow preventers that are meant to be used together with residential irrigation systems should be installed by professionals. The place where you’re installing that large backflow preventer will determine how much you’ll have to pay.
If you’re going with basement installation, that will cost you $200. Sewer line installations typically cost $250. Homeowners who need a backflow preventer for their sprinkler system should expect to pay $300 for labor expenses.
Cost Factors for Backflow Preventer Installation
Certain cost factors will affect how much you’ll have to pay for the installation of your backflow preventer. Let’s discuss those cost factors in this section.
Some areas in the country require homeowners to secure a permit before installing a backflow preventer. If you live in one of those areas, you can expect to pay $50 for the required permit.
You can find out if securing a permit is required for your intended installation by consulting with local officials. They should be able to give you an answer and they may even be able to help you secure the permit.
Another option is to hire a plumber. They can tell if you a permit is required.
The presence of additional features can drive up the cost of your backflow preventer. The increase can be quite noticeable too.
Backflow preventers that have extendable tops are three times as expensive as the basic models. One that features a plastic lid may cost five times as much as the default option.
Those additional features can improve the performance of the backflow preventer. They can also make maintenance easier. Whether or not those additional features are worth the extra money will be up to you to decide.
Inspection and Testing
Depending on where you live, you may need to get your backflow preventer regularly inspected and tested. In areas where testing is required, you may only have to pay the inspector $50. That’s also an annual fee so the cost of testing is very affordable.
Backflow testing is more expensive if it’s being conducted by a private company. You may find yourself paying $200 for testing.
Accessibility of Your Plumbing System
Lastly, the installers may alter their charges based on the accessibility of your plumbing system. They will charge more if it’s difficult for them to reach the spot where the backflow preventer needs to go. They may also have to work longer and that will increase your labor expenses.
Can I Install a Backflow Preventer Myself?
Whether you can install the backflow preventer depends on what type you’re working with. The ones that are designed for garden hoses are very easy to install. The backflow preventers that must be installed on water lines or other fixtures should be handled by professionals.
How Long Does a Backflow Test Take?
A backflow test shouldn’t take that long. It should be completed in about 25 minutes.Backflow tests only take longer than that if the tester discovers an issue with your plumbing. In that case, repairs may have to be administered before the test can be completed.
How Long Does a Backflow Preventer Last?
Backflow preventers can last for several years and even decades potentially. You just have to test them regularly and keep them properly maintained so they can last that long.
