FAQs
What is backflow and why is it dangerous?
Backflow occurs when water flows in the reverse direction, potentially pulling contaminants into your drinking water. This can include chemicals, irrigation runoff, bacteria, or sewage.
Is backflow testing required in BC?
Yes. Municipalities including Chilliwack, Abbotsford, and Lower Mainland cities require annual backflow testing for many commercial and multi-unit properties.
How often do I need to test my backflow device?
Once per year, or immediately after installation, repair, or any device replacement.
What types of backflow devices do you test?
We test and certify:
RP (Reduced Pressure Principle Assemblies)
DCVA (Double Check Valve Assemblies)

Do you handle the paperwork?
