We provide a comprehensive Backflow Prevention service in Hamilton and throughout Southern Ontario. Our certified team follows all protocol, beginning with completing a Cross Connection Control Survey of the building. We then work with an engineer and obtain the proper building permits on your behalf that satisfy the City’s requirements. Additionally, we perform an annual test of the Backflow Prevention device, tag the device, and fill out the proper forms to complete the service.


Backflow Prevention is becoming more predominant in many municipalities, including Hamilton, due to the risk of cross-contamination due to backflow.

What Is Backflow?

Under certain conditions, the flow of water in a supply line can be reversed and contaminants can flow backwards into the drinking water supply line. A building’s water supply usually flows from the source of water through to the plumbing water lines in the building. The potable water supply can become contaminated by accident, or through hazardous connections to the piping (cross connection). Backsiphonnage and backpressure reverse the flow of water in a supply line and, therefore, cause backflow into the water supply. Backflow can occur in any type of commercial or industrial building, and there are certain preventative measures that can be implemented in any building.

How Can Backflow Be Prevented?

First and foremost, this is a job that is best left in the hands of a professional. Any issues dealing with backflow are potentially dangerous; therefore, you should always contact a licensed technician to provide the best and safest backflow prevention products and services.


Through the use of specialized backflow preventers, which are mechanical plumbing devices installed in a plumbing system to stop potentially contaminated water from flowing backward through the pipes, our plumbers and technicians in Hamilton and throughout Southern Ontario can effectively prohibit the reversal of water through your plumbing. There are a wide range of devices to choose from that can be used to prevent backsiphonage and backpressure from adding contaminated fluids or gases into a fresh water supply system. Generally, the selection of the device is based on the degree of danger posed by the cross-connection and our plumbers, after careful investigation, will be able to make proper and personalized recommendations based on your specific plumbing system.


Preventing your drinking water from being contaminated should be on the top of your priority list, and Pitton Plumbing & Heating Inc has the resources and solutions you need. We offer backflow prevention services in Hamilton and surrounding areas. Contact us today!

Backflow Preventer Installation


Once the Cross Connection Control Survey is completed, we will follow your municipality’s guidelines in applying for a building permit. Every municipality states that the Backflow Prevention Device must be installed by a licensed plumbing contractor. We will then install the required Backflow Prevention Device.


Backflow Prevention Testing


The Backflow Prevention Device must be tested upon installation and then annually thereafter. Every time a test is completed by a Certified Tester, the device must also be tagged and a Test Report submitted to the corresponding City. Upon request, we can add you to our annual list as a reminder to perform the Annual Backflow Preventer Test.
