Backflow Prevention

Belleville Backflow Prevention

Keeping Your Water Supply Protected

Backflow is a plumbing issue caused by wastewater entering your home through an incoming line. This happens for one of two reasons: back siphonage or back pressure that forces contaminated water back into the main water line. To protect against the risk of backflow, all businesses and homes that utilize automatic irrigation systems are required to have a backflow prevention system installed, and Bel-O Cooling & Heating offers superior solutions to ensure your water supply remains protected.

Here at Bel-O Cooling & Heating, our family-owned company has been in business since 1959. We have gained a reputation for being trustworthy, reliable, and dependable, and we strive to uphold that reputation with every service we provide. We understand the importance of security and protection when it comes to your water supply, and we make sure every backflow device we install is up to high standards and functioning exactly as it should be.

What Is a Backflow Preventer?

A backflow preventer is a device that cuts off the flow of water to a particular branch of your plumbing system should the water ever start to flow backward in the direction it came from. Preserving this gap helps prevent the main water supply from being contaminated, and that makes them vital in a number of situations. Should your property need a new backflow preventer or your current preventer serviced, turn to Bel-O Cooling & Heating for a job done right.

We offer a full range of backflow services, including:

  • Backflow testing
  • Backflow inspection
  • Backflow repair
  • Backflow installation 

Because these devices are generally intricate and even small problems can lead to serious issues or even a total failure, a backflow prevention system is something that should only be installed by a plumber. Not only does your new systems need to be able to perform when called upon, but it needs to be able to do so with confidence and prevent leakage that could lead to potentially serious water contamination. This is particularly important for properties where reclaimed septic water could come in contact with a water line that carries fresh water, including homes that fall into this description.

  • "What a great value for the peace of mind!"
    We recently had a technician out to do a maintenance and cleaning of our furnace.The experience was great as he took his time to clean and inspect the system and to go over any findings/recommendations he had for us. We took advantage of the great maintenance plan they offer and look forward to having them back out in the spring to maintenance the AC. What a great value for the peace of mind!
