Backflow testing is an important part of protecting your building’s water supply. Whether you manage a commercial property, operate a business, or own a residential property with a backflow prevention device, regular testing helps ensure contaminated water does not flow backward into the clean water system.



For property owners in Saskatoon, backflow prevention is not just a technical plumbing issue. It is a safety, compliance, and property protection concern.

What Is Backflow?

Backflow happens when water flows in the opposite direction from where it is supposed to go. In a normal plumbing system, clean water flows into a building from the municipal supply. Backflow can occur when pressure changes cause water from the building’s plumbing system to move backward into the clean water supply.

This can happen because of:

• Sudden drops in water pressure
• Cross-connections between clean and contaminated water
• Faulty plumbing equipment
• Irrigation systems
• Boiler systems
• Commercial equipment connected to water lines

When backflow occurs, contaminants can enter the potable water supply. That is why many commercial and institutional properties require proper backflow prevention devices and routine testing.

Why Backflow Testing Matters

Backflow prevention devices are designed to stop reverse water flow. However, like any mechanical device, they need to be inspected and tested to confirm they are working properly.

Backflow testing helps confirm that:

• The device is functioning correctly
• Valves are sealing properly
• Pressure levels are within acceptable limits
• The water system is protected from potential contamination
• The property is meeting expected safety and maintenance standards

For commercial buildings, backflow testing is especially important because plumbing systems are often more complex than those in residential buildings.

Which Properties May Need Backflow Testing?

Backflow testing is commonly needed for:

• Commercial buildings
• Restaurants and food service businesses
• Medical and dental offices
• Industrial facilities
• Multi-unit residential buildings
• Schools and institutional buildings
• Properties with irrigation systems
• Mechanical rooms with boiler systems
• Buildings with fire suppression systems
• Facilities with specialized equipment connected to water lines

If your property has a backflow prevention device installed, it should be tested regularly by a qualified professional.

Signs Your Backflow Prevention System May Need Attention

Backflow problems are not always obvious, which is why testing is important. However, property owners and managers should pay attention to warning signs such as:

• Changes in water pressure
• Discoloured water
• Unusual taste or odour from water
• Leaking around the backflow device
• Visible corrosion or damage
• Failed previous inspection
• Plumbing system modifications

If you notice any of these issues, it is best to schedule service as soon as possible.
