We offer comprehensive backflow prevention services in Hamilton and Southwestern Ontario. Our certified team follows all protocols, 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 caused by backflow. You can reach out to us to request a quote or book a service.

What Is Backflow?

Under certain conditions, the flow of water in a supply line can be reversed, and contaminants can flow backward 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). Back-siphonage and backpressure reverse the flow of water in a supply line and, therefore, cause backflow into the water supply. Backflow can occur in any commercial or industrial building and contaminate the water, posing a serious health threat. Certified backflow specialists can install backflow preventers to prevent reversed water from entering the freshwater supply system. This process is known as backflow prevention.

Causes of Backflow

There are two major causes that result in backflow:


The water flowing into your plumbing system has a lower pressure than the existing water.


The water flowing into your plumbing system has a higher pressure than the existing water. 

With these issues present, water starts running the wrong way throughout your plumbing system and results in contamination.

Understanding the Dangers of Backflow

Plumbing is one of the vital systems for any property, so it is essential to take preventive measures to lower the risk of potential problems. Backflow can eventually result in the following issues:

Promoting corrosion of pipes
Creating leaks and breaches
Posing a greater risk to health

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 backflow specialist 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 in Hamilton can effectively prohibit the reversal of water through your plumbing. There is a wide range of devices to choose from that can be used to prevent back-siphonage and backpressure from adding contaminated fluids or gases into a freshwater supply system. Generally, the selection of the device is based on the degree of danger posed by the cross-connection and our specialists, 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 at 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!

Cross Connection Control Survey: Only certified testers like us are eligible to conduct a Cross Connection Control Survey. We can conduct the survey to identify cross-connections and ascertain which type of backflow preventer device is apt for your building.

Testing and Tagging: 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 must be submitted to the corresponding city.

Installation of Backflow Preventers: 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 installer. We will then install the required backflow prevention device.

Backflow Preventer Repairs and Maintenance: Backflow preventers can become less efficient over time and need regular upkeep. Apart from installing the device, we also offer repair and maintenance services to ensure optimal performance.

Annual Tests and Inspections: Regular testing of backflow preventers is necessary to check if they are working properly. We provide annual testing services. Upon request, we can add you to our list as a reminder to perform the yearly backflow preventer test.
