How much does it cost to replace a backflow preventer?
Cost to replace a backflow preventer varies by valve size, access, and local code needs. Apollo Plumbing gives a firm, upfront price after an on-site inspection, and a licensed plumber confirms costs before work begins. We stock parts to finish most replacements in one visit and provide written guarantees. Service is available across Seattle, Everett, and nearby areas.
Quick factors that affect price:
- Valve size/type and brand
- Location and accessibility (indoor, vault, landscaping)
- Testing, permits, and post-install inspection needs
