RPZ 2½”- 10” RPZ 2½”- 10”

Modification Overview  Production of the RPZ in sizes 2½ - 10” began in 1993 and is current.

Single Access Cover Removal  The RPZ cover is spring loaded and sealed by the diaphragm. ** Hold cover firmly while removing bolts. ** Hold cover firmly while removing bolts.

Single Access Cover Removal  Lift cover straight off.  Remove RV stem assembly and spring from body.

Check Valve Removal  Check valve modules.  Modules are o-ring sealed and secured by spring clips.  Pinch together the exposed ends of the clip and pull away from module. ** Use adjustable pliers if necessary. ** Use adjustable pliers if necessary.

Check Valve Removal  Once the spring clips are removed, the modules can be pulled straight out of body.  #1 check must be removed before #2 can be removed.

Disassemble Check Valve  21/2”-3” sizes springs are not captured.  4”-8” spring tension is captured.  Unscrew check valve stem from disc holder.  Place a wrench on the spring retainer and a wrench on the disc holder.

Disassemble Check Valve  Loctite is used on the threads of the stem and disc holder.  Sometimes an impact or much force is needed to break this free.

Check Disc Replacement  Once check module is disassembled, the disc holder, retainer, and disc are free.  Reassemble in reverse order.

Check Seat Removal  The check seat is part of the module and should not be removed.  If the seat is damaged, the entire module must be replaced.

Check Valve Reassembly Notes  Lubricate o-rings.  Push checks into body.  Replace spring clips in reverse order.

RV Stem Removal  The RV stem and spring are situated between the check valves and are free once the single access cover is removed.

RV Seat Removal  Unless damaged there is no need to remove RV seat.  The seat is pushed firmly into body and is o-ring sealed.

RV Diaphragm Replacement  The diaphragm is located on the upper stem.  Unscrew the RV piston from the stem.  Reassemble in reverse order.

RV Disc Replacement  The RV disc is located on the lower stem.  Unscrew the disc retainer from the RV stem.  Reassemble in reverse order.

RV Reassembly Notes  Center the spring over the RV seat.  Position the RV stem into the body.  Lubricate plunger o- ring.

Single Access Reassembly Notes  Place cover over RV assembly.  Make sure the diaphragm does not block the 3 test cock ports in the body. ** Place lid bolts in cover to help position the diaphragm correctly. ** Place lid bolts in cover to help position the diaphragm correctly.
