How often does a backflow preventer need to be inspected?
Backflow preventers should be tested and inspected once per year. Most municipalities require annual testing, and we provide certified testing and documentation for RPZ and other assemblies. For sprinkler systems, schedule the check before irrigation season to catch leaks and ensure code compliance. If parts are worn, we can rebuild; freeze-cracked bodies need full replacement. We serve Denver, Thornton, and nearby communities.
