How much does it cost to replace a backflow preventer?

There isn’t a one-size price for backflow preventer replacement. A licensed Appleton Campbell plumber will inspect your setup and give you upfront pricing before work begins. Costs vary by valve type and size, where it’s installed, accessibility, and any needed shutoff or piping adjustments. Most customers in Fredericksburg and Ashburn can expect a same-day assessment and clear options.

• What affects price: valve type/size, location/access, shutoff condition, piping changes, winterization needs.
