How much does it cost to replace a backflow preventer?
We price backflow preventer replacement by the job after an on-site assessment, and we confirm the total before work begins. Actual cost varies in Petaluma and Novato based on device size, location/access, parts, and whether your Water District requires inspection or testing. Exact pricing depends on inspection. A technician will confirm costs on site.
