Our review of the Febco 905-212 Bonnet Repair Kit finds it best suited for homeowners and irrigation pros who need a quick, OEM-equivalent repair to a 1in or 1-1/4in pressure vacuum breaker. The kit contains the bonnet, O-ring, spring, E-ring, washer, stem, rubber disc and poppet so you can replace the bonnet and poppet assembly without sourcing separate parts. For anyone facing leakage or worn internal parts, this repair kit is a practical, cost-effective alternative to replacing the entire valve or hiring a technician.

Key Features

• Complete factory kit: Includes bonnet, O-ring, spring, E-ring, washer, stem, rubber disc and poppet so the full bonnet and poppet assembly can be restored in one service visit.
• Easy servicing: Designed for straightforward installation that requires no special tools, letting a competent DIYer complete the repair in minutes.
• Genuine parts: Factory replacement components match original specifications to help the pressure vacuum breaker operate at intended efficiency.
• High-quality materials: Parts are engineered to withstand repeated use and the stresses of irrigation systems, reducing the chance of premature failure.
• Fits common sizes: Specifically made for 1in and 1-1/4in #765 vacuum breakers and backflow preventers so compatibility is clear and reliable.

Who It's For

The Febco 905-212 kit is aimed at homeowners, landscapers and irrigation technicians who want a direct, economical repair for a leaking or worn pressure vacuum breaker without replacing the entire device. If you are comfortable doing basic plumbing service and can stop water flow to the device, this kit restores internal components quickly.

Those who should look elsewhere include users with different vacuum breaker models or sizes, or anyone who prefers to replace the entire backflow preventer rather than repair individual components. If you need parts for sizes other than 1in or 1-1/4in, this kit will not be suitable.
