Backflow Prevention Services

Backflow prevention protects potable water from contamination caused by reverse water flow. When pressure changes occur within a plumbing system, contaminated water can flow backward into the clean water supply. This creates a serious risk of backflow water contamination in commercial and industrial environments.

A properly installed backflow preventer, sometimes referred to as a backflow valve, prevents cross contamination by isolating the potable water system from hazardous conditions. Backflow prevention services are a required part of cross connection control programs throughout Ontario.

Prevent backflow issues before they compromise your water system. Routine inspection and maintenance are essential to long term plumbing backflow protection.

Installation Services

We provide code compliant backflow installation and backflow preventer installation for new construction, system upgrades, and retrofits.

Our installation services include:

• RPZ valve installation

• Double check valve assembly installation

• Pressure vacuum breaker installation

• Fire protection backflow systems

• Industrial backflow systems

• Commercial backflow prevention systems

We assess system hazard classification, building type, and municipal backflow inspection requirements to determine the correct device and configuration. Our installations meet Ontario backflow regulations and local municipal backflow requirements.

Backflow installation cost varies depending on device size, accessibility, and system complexity. We provide detailed estimates with no surprises.

Testing & Certification

Backflow testing is required annually for most commercial and industrial properties across Ontario. We provide annual backflow testing in Brampton, annual backflow testing in Mississauga, and annual backflow testing in Milton for properties that must comply with municipal cross connection control programs. Our team performs certified backflow testing and backflow prevention testing in accordance with municipal cross-connection control program standards.

Testing services include:

• Annual backflow testing

• Commercial backflow testing

• RPZ valve testing

• Double check valve testing

• DCVA testing

• Backflow device certification

During testing, our licensed backflow tester verifies check valves, relief valves, pressure differentials, and overall system integrity. If the device passes, we issue annual backflow certification for compliance reporting.

Certified backflow testing ensures ongoing backflow compliance and protects your property from enforcement action.

Repair Services

If a device fails inspection, prompt backflow repair is necessary to restore protection and compliance.

Our backflow preventer repair services include:

• Internal component replacement

• Relief valve repair

• Check valve repair

• Complete rebuilds

• Re testing after repair

Backflow repair cost depends on device condition and parts required. We provide efficient diagnostics and rapid repair to reduce operational downtime for commercial and industrial facilities.

Types of Devices

We service and install all major backflow preventer types used in Ontario.

RPZ Valve

An RPZ valve provides maximum protection in high hazard environments. RPZ valve testing and RPZ valve installation are common in restaurants, medical facilities, and industrial buildings.

Double Check Valve Assembly

A double check valve assembly is typically used in moderate hazard commercial systems. Double check valve testing and DCVA testing are essential for ongoing compliance.

Pressure Vacuum Breaker

Often used for irrigation systems and lower hazard applications.

Each device must meet municipal backflow inspection requirements and undergo routine testing to maintain certification.
