Why do I need backflow prevention?

Backflow is the undesired reversal of water flow between the city’s supply and a private system. Backflow can cause contaminants to enter into the drinking water supply system and plumbing. The two causes for backflow are back-pressure and back-siphonage. Contact us today to learn more or book a licensed plumber.

Municipalities in the Peterborough area and Durham Region require commercial/industrial facilities to maintain and install backflow prevention measures. Doyle Plumbing’s licensed plumbers are certified to professionally complete backflow testing and document the required tests with your municipality. A backflow preventer device (or check valve) will isolate the municipal water supply from the private water system in order to keep the water supply safe.

Just wanted to let you know that Kirk was at my home to correct a glitch with our tankless water heater - gotta' say, couldn't be happier.

Doyle sent two plumbers to my house to fix a leak in my kitchen. The best work I’ve ever seen, professional and courteous.

We had Doyle’s come to fix our furnace. The office staff are great, the guys work long hours so people like us have heat and don’t freeze!

I’ve struggled with my air conditioning unit at my business for 5 years. The guys at Doyle were helpful and brainstormed several solutions. In the end, they fixed it!
