3000CIV 21/2”-10”

Modification Overview Production of the 3000CIV (Watts709DCDA) began in 1998 and was discontinued in 2007. The 3000CIV utilizes a ½” 007 for the 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. 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”.
