Reduced pressure zone assembly — selected official service parts
The 825Y family includes original, angle, and lead-free variants. This map keeps original and LF part paths separate rather than treating every 825Y-looking body as interchangeable.
Confirm 825Y versus LF825Y and the nominal size before ordering. This page does not claim to cover every relief-valve, check, or sensor configuration in the wider 825Y family.
Field reference
825Y, LF825Y, and rubber-kit designations.
Record the full prefix and size before using a catalog reference. A lead-free kit material label alone does not establish compatibility with every LF assembly.

| FRK 825Y-RT, 3/4–1 1/4 in | FEBCO identifies this rubber kit as ordering code 905111, compatible with 825Y in the stated band. | Compare both the descriptive reference and order code before purchase. |
| RT versus RTS | Rubber material and service designations can differ. | Do not replace RT with RTS solely because a listing looks similar. |
| Check seats or relief-valve scope | A rubber kit is not a universal check-seat or complete assembly rebuild. | Use the diagnosed component and exact parts record. Continue → |

Similar-looking assemblies can use different internals. A search result or pipe size alone is not enough.
- 01
Read the full marking: 825Y, 825YA, LF825Y, and LF825YA are related but may use different published kit references.
- 02
A check-seat-and-ring kit is not a complete rubber-parts kit, and neither should be treated as a full internal rebuild.
- 03
Flood-sensor accessories appear alongside repair parts on manufacturer records but are not internal repair kits.
Before return to service
A matching kit is not a passed assembly.
Stop for body damage. Cracks, distortion, severe corrosion, or freeze damage can move the job from internal service to replacement.
Test after repair. Where the assembly is regulated, the governing utility or authority decides tester approval, reporting, and deadlines.
Use the current instructions. Part references can change. Confirm availability and supersession with the manufacturer or an authorized supplier.
