Backflow Prevention

Certified Protection for Your Water Supply

Backflow prevention is a critical safeguard that protects clean, potable water from contamination caused by pressure changes within a plumbing system. Whether required for municipal compliance or risk mitigation, properly installed and tested backflow devices help ensure public health, system safety, and uninterrupted water service.

Juddco Mechanical provides complete backflow prevention solutions for commercial, industrial, and residential properties across the GTA — from installation and annual testing to repairs and full municipal documentation.

Backflow Services


Backflow Device Installation

Juddco installs CSA-approved backflow prevention devices designed to meet local municipal codes and site-specific requirements. Our team assesses your system layout, usage risk, and water supply conditions to determine the correct device type and placement. All installations are completed by certified professionals to ensure long-term performance and compliance.

Annual Testing & Certification

Municipal regulations require backflow preventers to be tested annually by a certified tester. Juddco performs precise testing using calibrated equipment and provides official certification reports. We also submit all required documentation directly to the municipality, helping you avoid missed deadlines, penalties, or service interruptions.

Compliance, Permits & Documentation

Backflow compliance often involves permits, engineered drawings, and municipal approvals. Juddco manages the entire administrative process on your behalf — coordinating with inspectors, completing required filings, and ensuring your system meets all local code requirements. One contractor, zero paperwork stress.

Backflow Repairs & Maintenance

If a backflow device fails testing or shows signs of wear, Juddco provides prompt and effective repairs. From internal seals and valves to full component replacement, our technicians restore devices to proper working order while minimizing downtime. Preventative maintenance services are also available to extend system lifespan.

Commercial & High-Risk Applications

Juddco specializes in backflow solutions for higher-risk systems, including commercial buildings, restaurants, multi-unit residential properties, irrigation systems, and fire protection lines. These environments demand strict compliance and precise installation — our experience ensures your system is protected, tested, and approved.

Why Backflow Prevention Matters

Backflow incidents can allow harmful contaminants to enter the potable water supply, posing serious health risks and potential legal liability. Properly installed and regularly tested backflow preventers reduce this risk while ensuring your property remains compliant with municipal regulations. Regular testing also helps identify issues early, preventing costly emergency repairs or water service disruptions.
