How much does it cost to replace a backflow preventer?

Backflow preventer replacement cost depends on the assembly type, size, location, and any needed repairs. We replace county‑approved devices (double check, double check detector for fire systems, and lead‑free reduced pressure assemblies) and confirm pricing on site with flat‑rate, no‑surprise pricing. After work, we test the device (typical tests take about 30 minutes when no issues exist) and submit the required report to the county. We serve Denver, Highlands Ranch, and nearby communities.

• Cost factors: device type (DC, DCDA, RP), pipe size/access, and repair needs.
