What is Backflow?

Backflow is a serious plumbing issue that occurs when contaminated water or other substances flow backwards into the clean water supply. This can happen due to a variety of factors, including:

  • Cross-connections: When a non-potable water source is connected to the potable water supply
  • Backpressure: When the pressure in the contaminated source is greater than the pressure in the potable water supply
  • Backsiphonage: When there is a negative pressure in the potable water supply, causing contaminated water to be drawn back into the system

Backflow can introduce harmful contaminants into your drinking water, posing serious health risks to you, your family, and your community. That’s why it’s crucial to have a reliable backflow prevention system in place and to schedule regular backflow testing and maintenance.

How Does WNY Plumbing Help?

At WNY Plumbing, we offer a comprehensive range of backflow services to keep your plumbing system safe and compliant with local regulations. Our services include:

  1. Backflow prevention device installation
  2. Backflow device testing and certification

Our experienced plumbers will work with you to identify the best backflow prevention solution for your specific needs, whether you’re a residential, commercial, or industrial property owner. We use only the highest quality backflow prevention devices from trusted manufacturers, ensuring long-lasting protection for your plumbing system.

The Importance of Regular Backflow Testing

Backflow prevention devices are essential for protecting your water supply, but they can only do their job if they’re functioning properly. That’s why regular backflow testing is so important. In fact, most local municipalities require annual backflow testing to ensure compliance with health and safety regulations.

During a backflow test, our certified plumbers will thoroughly inspect your backflow prevention device to ensure that it’s operating correctly and providing adequate protection against contamination. If any issues are found, we’ll work quickly to repair or replace the device, keeping your water supply safe and your property compliant.

Awesome service, also great price. My tech was Tyler. Great guy, also very kind and thoughtful of residence. Went the extra step and cleaned up our bathroom when he was finished. Stuck around for a bit to make sure everything was squared away before leaving as well. Definitely recommend as a first option in the WNY area.

WNY Plumbing exceeded my expectations from start to finish. The team was prompt, courteous, and incredibly knowledgeable. They took the time to explain everything clearly, and their work was not only efficient but beautifully done. It’s rare to find a company that combines skill with such genuine care for their clients. I’ll absolutely be calling them again—and recommending them to anyone in need of reliable, top-notch plumbing services. Thank you.

Mike did an amazing job fixing my shower handle issue! I had several plumbers come out and state they were not knowledgeable regarding this handle and could not work on it. WNY Plumbing (Mike) knew exactly what to do. Mike was professional, friendly and was able to get the job done in no time with minimal impact to me. I highly recommend WNY Plumbing!

We could not be happier with all the plumbing work Tyler did for us, and the bill was a pleasant surprise as it was very reasonable.

Mike has done a lot of work at my house. He installed two utility sinks and did a wonderful job a couple of years ago. Yesterday he fixed my booster pump problem quickly and efficiently. He also showed me what I should be doing for my hot water unit while he waited for glue to dry! Because he knew exactly what was wrong with the booster pump and repaired the problem, my water irrigation system is now working properly—saving me about a thousand dollars in unneeded valve replacement! The gang at WNY Plumbing always respond quickly and get the job done. They’re on my team!
