Ensuring the safety and quality of our drinking water is a critical responsibility, and one that falls under the expertise of licensed plumbers. One key tool in safeguarding our potable water is the backflow prevention device. But what exactly is this device, and why is it so crucial for our water systems?

What is a Backflow Prevention Device?

A backflow prevention device is essentially a one-way valve designed to keep our water clean and safe. It allows water to flow in only one direction—out from the main supply—preventing any contaminated water from flowing back into our drinking water. This mechanism is vital for protecting our water supply from pollution that could potentially arise from private properties.

When is a Backflow Prevention Device Required?

Certain scenarios and features on your property necessitate the installation of a backflow prevention device. These include:

• Irrigation Systems: Prevents potential contaminants from garden and lawn watering systems from entering the main supply.
• Fire Hose Reels or Hydrants: Ensures that water used in emergency situations does not return to the main supply.
• Vehicle or Bin Wash Down Bays: Protects against pollutants washing back into the water supply.
• Commercial or Industrial Activities: Any machinery or activities connected to the mains, which could introduce contaminants.
• Water Outlets Near Pollutants: Areas close to grease traps, chemicals, or other pollutants need this device to maintain clean water standards.

What Causes Backflow?

Backflow can occur when there is a sudden change in water pressure, such as during a burst water main or while firefighting. These pressure changes can cause water to flow backwards from private properties into the public water supply, potentially bringing pollutants with it.

By understanding and professionally installing backflow prevention devices, we help ensure that our community’s drinking water remains uncontaminated and safe for everyone. If you have any of the above features on your property, it is essential to check whether you have a backflow prevention device in place and ensure it is functioning correctly.
