Modification Overview  Production of the 5000CIV (Watts 909RPDA) began in 1998 and is current.  The 5000CIV utilizes a ¾” 909 bypass assembly.

Check Cover Removal  Cover is o-ring sealed.  Loosen bolts ½”. Spring load is now released from the cover and retained by the check subassembly.  Verify spring load before removing all the bolts.

Check Valve Removal  Center stem guided check assembly.  Disc & spring subassembly.  Slide subassembly straight out of seat and body.

Check Seat Removal * 21/2-3” Seats removed by ¼ turn twist. * 21/2-3” Seats removed by ¼ turn twist.  4”-10” Seats secured by two retaining wires. Each wire 10” long.  Pull one wire clockwise / one wire counter clockwise.  Seats are o-ring sealed and pull straight out of body.

Check Disc Replacement  Remove retaining nut for sizes 21/2”-4”.  Remove allen head screws in retainer plate for sizes 6”-10”.

RV Cover Removal  RV Cover is sealed by the diaphragm.  Loosen cover bolts ½”. Spring load is now released from the cover and retained by the bottom plug assembly.  Verify spring load before removing all the bolts.

RV Stem Removal  The piston subassembly can be lifted straight up and out of the body.  The bottom plug subassembly (4”-10”) contains the spring and does not need to be removed for normal service. * For removal: simply unscrew from outside the RV body. * For removal: simply unscrew from outside the RV body.

RV Seat Removal  Unless damaged, there is no need to remove the RV seat.  RV seat is threaded and o-ring sealed.

RV Rubber Replacement  Replace diaphragm.  Replace wiper seal and piston o-ring. Apply lubricant to the o-ring.  Replace RV disc. * Hold upper guide fin and unscrew pressure plate. Replace disc assembly and stem o- ring. * Hold upper guide fin and unscrew pressure plate. Replace disc assembly and stem o- ring.
