Why backflow testing matters
Backflow prevention assemblies protect drinking water from contamination caused by pressure changes, damaged components, or failed valves. When these devices are not working correctly, contaminants from irrigation systems, fire lines, or other sources can reverse direction and enter the public water supply.
Most municipalities in Colorado require annual testing by a certified technician. BlueLine provides the testing, documentation, and repair follow-up to keep your property in compliance and your water system protected.
