Bi-Directional Backflow Preventer Repair Kit for 3/4" — 1" 975XL & 975XL2
The iFJF Backflow Preventer Repair Kit includes everything needed to rebuild the check valve assembly on 3/4-inch and 1-inch bi-directional backflow preventers — specifically the 975XL and 975XL2 series. When your backflow preventer fails its annual certification test or develops a persistent leak, replace the worn internal components instead of the entire assembly at 5x the cost.

FAQ
Q: Will this fit my specific backflow preventer?
A: This kit is designed for 3/4-inch and 1-inch 975XL and 975XL2 bi-directional backflow preventers. Verify your model number — it's stamped on the brass body of the assembly.
Q: Do I need a plumber to install this?
A: Many DIY homeowners complete this repair themselves. However, check local regulations — some jurisdictions require a licensed backflow technician to service and re-certify backflow preventers after internal repairs.
Q: What symptoms indicate I need this repair kit?
A: Failed annual certification test, water leaking from the relief valve port, low system pressure, or visible corrosion/deterioration on the check valve components during inspection.
Q: Can I use this on a 2 inch backflow preventer?
A: No — this kit is specifically sized for 3/4-inch and 1-inch assemblies. 2-inch backflow preventers use larger internal components that are not compatible with this kit.
Q: Does this kit include the test cocks?
A: No — the test cocks (small ball valves used for testing) are external to the check valve assembly and are not included in this kit. This kit focuses on the internal check valve and relief valve wear components.
