Common causes of backflow

The water supply system is designed to make sure that water flows to your property under pressure. If the water pressure is not maintained, there is a chance it may be drawn back into the water main, with the potential to contaminate the drinking supply.

• Water pressure can be affected when;
• A break in the water main
• Heavy use downstream reduces the water pressure upstream
• You are using your water at a higher pressure than supplied by Sydney Water
• The water mains are being worked on by Sydney Water

Why do you need backflow prevention testing?

To comply with Sydney Water Authority standards, and if you choose not to get your water supply system tested, backflow can become a horrible problem which can cause major health risks.
