Backflow Testing & Prevention Services in Coquitlam and Vancouver, BC

At Coquitlam Plumbers, we specialize in professional backflow testing and prevention services to ensure the safety and purity of your water supply.

Backflow occurs when the flow of water reverses direction, allowing contaminants from irrigation systems, industrial fluids, or sewage lines to enter your clean drinking water. This can pose serious health risks and may lead to non-compliance with local water safety regulations.

As a licensed plumbing company serving Vancouver, BC, and the surrounding areas, we provide certified backflow testing, prevention, and device installation to protect your water system from contamination. Whether you are a homeowner, business owner, or property manager, our experienced team ensures your backflow prevention system meets all regulatory requirements and functions effectively.

What Is Backflow and Why Is It a Serious Issue?

Backflow occurs when there is a change in water pressure within a plumbing system, causing contaminated water to flow backward into the clean water supply. This can happen due to events such as a sudden drop in water pressure from a burst pipe, high demand on the system, or faulty cross-connections. Without a proper backflow prevention device, harmful substances such as chemicals, bacteria, fertilizers, and waste materials can enter your drinking water.

The consequences of backflow contamination can be severe. Exposure to polluted water can result in serious health hazards, leading to gastrointestinal illnesses, bacterial infections, and even exposure to toxic substances. Additionally, businesses—especially those in industries such as food service, healthcare, and manufacturing—must comply with strict water safety standards to prevent contamination. Routine backflow testing is essential to ensuring that your water supply remains safe, clean, and legally compliant.

Our Professional Backflow Testing Services

At Coquitlam Plumbers, we offer comprehensive backflow testing services to verify the functionality of your backflow prevention system. Many municipalities, including Vancouver, BC, require annual backflow testing for businesses and certain residential properties to comply with local health and safety regulations. Our certified backflow prevention specialists conduct thorough inspections to ensure your backflow preventer is working correctly.

Our testing process includes:

• Visual inspection of your backflow prevention device to check for leaks, corrosion, or visible damage.
• Pressure testing to measure water flow and ensure there are no signs of reverse contamination.
• Verification of check valves and relief valves to confirm that they are operating properly.
• Documentation and compliance reports to submit to local authorities, ensuring that your property meets all safety and municipal requirements.

If we detect any issues during our testing, we will provide immediate solutions, including repairs, replacement, or new installations of backflow prevention devices to ensure continued protection of your water supply.

Backflow Prevention Device Installation & Repair

Preventing backflow is crucial to maintaining a safe and compliant plumbing system. If your property does not have a backflow prevention device, or if your existing unit is outdated or malfunctioning, our team at Coquitlam Plumbers can install, repair, or replace the appropriate device for your system.

There are different types of backflow preventers, and we help you choose the best one based on your specific needs:

• Reduced Pressure Zone (RPZ) Devices – These are the most effective for high-risk applications where contamination risks are severe, such as commercial and industrial facilities.
• Double Check Valve Assemblies (DCVA) – Commonly used in fire protection systems, sprinkler systems, and commercial properties, DCVAs provide a strong layer of protection against contamination.
• Pressure Vacuum Breakers (PVB) – Often installed in residential irrigation systems, PVBs prevent the reversal of contaminated water into household plumbing.

Our licensed technicians handle the installation, repair, and maintenance of all types of backflow prevention devices, ensuring your property remains compliant with BC plumbing codes and health regulations.

Who Needs Backflow Testing and Prevention?

Backflow testing is essential for both residential and commercial properties, especially those that use complex plumbing systems, irrigation setups, or industrial-grade water connections. Certain properties are at higher risk of backflow contamination and may be legally required to have annual backflow testing and certification.

The following types of properties typically require backflow prevention measures:

• Commercial buildings – Restaurants, hotels, shopping malls, office buildings, and warehouses.
• Industrial facilities – Factories, chemical plants, and processing plants that use water for manufacturing or production.
• Residential properties – Homes with sprinkler systems, private wells, or irrigation systems that can cause cross-contamination.
• Medical and healthcare facilities – Hospitals, dental offices, and clinics that require strict water safety measures.
• Schools and government buildings – Public and private institutions that need to protect public water supplies.

If you are unsure whether your property requires backflow testing, our team can conduct an assessment to determine if you need a backflow prevention device and ensure compliance with local laws.
