Backflow Prevention & Testing in Westminster
Backflow prevention protects your drinking water from contamination by ensuring non-potable water doesn't flow back into your clean water supply. Property owners in Westminster are typically required to have backflow prevention devices installed and regularly tested, especially for commercial properties or those with irrigation systems, to comply with local health and safety regulations.
Neglecting backflow prevention can lead to serious health risks by contaminating your potable water supply with harmful substances. Non-compliance with Westminster regulations can also result in significant fines and water service interruption.

What affects the cost of Backflow Prevention & Testing
Frequently asked questions
How often is backflow testing required in Westminster?
In Westminster, most backflow prevention devices, especially for commercial properties and irrigation systems, require annual testing and certification to ensure they are functioning correctly and to maintain compliance with local water district regulations.
What is the difference between an RPZ and a PVB?
An RPZ (Reduced Pressure Zone) assembly is designed for high-hazard applications and provides the highest level of protection against backpressure and backsiphonage. A PVB (Pressure Vacuum Breaker) is used for low-hazard applications and primarily protects against backsiphonage.
Do I need a backflow preventer for my irrigation system?
Yes, in Westminster, nearly all irrigation systems are required to have a backflow prevention device installed. This prevents fertilizers, pesticides, and other contaminants from your lawn from entering your home's or the municipal water supply.
What happens if my backflow preventer fails the test?
If your backflow preventer fails its annual test in Westminster, it indicates a malfunction that could compromise water safety. Our technicians will diagnose the issue, perform necessary repairs or recommend replacement, and retest the device until it passes certification.
