Superb Plumbing Solutions That Fit Your Budget

Schedule Now

The reverse flow of water through clean water lines is called backflow. It can be a serious health hazard if it contains chemicals, fertilizers, sewage, and other contaminants. When water is siphoned into the drinking water from factories, pools, and other sprinkler systems, it can cause serious health issues.

While the United States has one of the safest public water worldwide, it records a staggering 32 million cases of acute gastrointestinal illness annually. Unfortunately, one of the culprits is backflow from contaminated water. To ensure your water is safe, you will need backflow testing services. This is where we come in.

At Ranger Rooter, we have in-depth knowledge and understanding of the legal requirements and issues related to backflow prevention. We adhere to the highest level of due diligence to ensure water safety through testing, diagnostics, and repairs. Give us a call and let us know how we can help.

A Backflow Testing Company You Can Depend On

Backflow testing is done to evaluate your plumbing system and determine if backflow is occurring. The process is fast and straightforward. During testing, our experienced and certified plumbers will carefully assess how well your backflow preventers are working. These devices are designed to keep the flow of water in the correct direction.

They also function as barriers that can ensure harmful contaminants will not enter the community's potable water supply. These helpful devices are also typically located in the cross-connections linking the clean water to the applications where it is used. For instance, they can be found in sprinkler irrigation systems.

Preventers hinder any manure or chemical fertilizers from back flowing into the water supply and contaminating the water. During testing, our dependable plumbers will open and close the valves of the prevention device to gauge if it is functioning properly.

We will also look for gauge movement, leakage, and other signs of malfunction. If all the valves are working as they should, you are all set. Otherwise, our plumbers can carry out any needed repairs to ensure your water is clean and safe. If you need dependable and affordable testing, call us today.

The Importance of Backflow Testing Services

The importance of backflow testing cannot be overstated. Below are some of the reasons why it is important:

Health Concerns

Ensuring health concerns are kept at bay is one of the primary reasons for testing. If your water travels backward, it can get contaminated. In home settings, this can have serious health repercussions as you can end up drinking contaminated water.

Building Damage

If water travels backward, it can hit the walls and cause significant damage over time. If it hits the same spot for a long time, the walls can weaken and crumble.

Environmental Concerns

Contaminated water that goes back to your sewer will eventually make its way to the lakes and oceans. Ensuring you won’t contribute to the contamination of lakes and oceans should be enough reason to have your preventer checked regularly.

If you use in-ground irrigation systems like lawn sprinklers, it would be wise to have a preventer. You might also need a backflow assembly if you have a separate irrigation meter at home.

The same principle applies if you have a water-serviced dock at home. If any of the scenarios are true in your case, it is ideal that you get backflow prevention testing at least once yearly.

How to Pick the Right Type of Backflow Preventer

When picking a backflow preventer for your home, keep in mind the following important factors:

Maintenance and complexity of installation

A pressure vacuum breaker (PVB) or spill-resistant vacuum breaker (SVB) is easier to maintain and install. A reduced pressure (RP) backflow assembly is trickier to install and will require complex maintenance.


According to the U.S. Environmental Protection Agency (EPA), the cost of a backflow preventer can vary depending on the size, complexity, and type of assembly or device. When it comes to assemblies, a PVB is considered the most economical option, while an RP is one of the most expensive.

Range of Coverage

Assemblies like PVBs have limited uses since they won't be able to prevent back pressure effectively, especially in high-hazard scenarios. Identifying the right level of protection for the household can help you determine the type of backflow prevention assembly that suits you best.
Our expert plumbers are certified in RPZ and backflow testing and we use top-of-the-line testing equipment. If there are any problems, we will provide a personalized solution that will work best for your system.

My bathroom facet had lost all pressure for some reason. While driving to work, I had just happened to hear a commercial for Rooter Ranger offering a special for a plumbing evaluation. I called to schedule and appointment, and within 45 minutes, a gentlemen named Jason from Rooter Ranger was here.... He looked at the sink and within minutes, he determined that it was just the filter on the facet. With a few twists of a wrench, it was fixed. He shook my hand, told me to have a good weekend, and said “this one is on the house. Please remember us for next time.”What an unexpected and great experience. I will call Rooter Ranger next time and ask for Jason!read more

The experience we had working with the guys from Rotor Ranger was actually pretty good considering we had a pretty big problem with drainage and roots in pipelines. Jared was very clear on what was needed and explained everything that would be done, and got it scheduled and moving towards repair... very quickly. The service guys took care of the back ups and the cleaning of the pipes very quickly and professionally. Barney, Dylan, Roger and Marcelino were very helpful, friendly & competent in their perspective jobs! it doesn’t even look like they dug up my front yard to take care of the clogged up pipe. Everything is put back exactly as it should be. Job well done. I would recommend these guys very highly. Thanks!read more

I 100% recommend Cody from Rooter Ranger. I've owned several high end homes and am extremely selective when choosing a plumber and any home service company. There were so many choices and I fortunately picked the right one and then immediately cancelled 3 additional appointments my wife and I had... made with other companies.This was beyond great service. The experience with Rooter Ranger was top notch and Cody's knowledge, troubleshooting, perseverance and ingenuity to solve the problem with my kitchen plumbing was beyond impressive. It was truly a different level of care and experience and I am sincerely most grateful for his excellent work. My thanks!!! David (La Jolla homeowner)read more

Rooter Ranger technician Frank Arias was very knowledgeable about his job. He fully explain the issue and makes honest recommendations for repairs. He did an excellent job in conducting hydro jet cleaning both kitchen and main sewer lines and removed the clog. He even fixed the leaking kitchen sink... drain line. He definitely educated me about house plumbing/drains…. I highly recommend Rooter Ranger!!! Thank you!!read more
