CX Manual Flushometers
TROUBLESHOOTING GUIDE
1. Flushometer does not function (no water/flush).
A. Ensure water supply to valve is turned on.
B. Shut off sleeve is in closed position. Turn counterclockwise to open water ow.
C. Plunger screw is not adjusted properly. Adjust screw using depth guide.
2. Volume of water is not sufficient to evacuate the bowl.
A. Shut off sleeve is not open wide enough. Adjust shut off sleeve for desired delivery of water volume.
B. Urinal piston parts installed in a Closet ushometer. Replace piston with proper Closet piston (1.6 gpf/6.0 Lpf or 1.28 gpf/4.8 Lpf)
C. Water supply volume or pressure is inadequate (low). If the xture does not siphon or evacuate the bowl, steps must be taken to increase the
water supply pressure and/or volume. Contact the xture manufacturer for minimum water supply requirements of the xture.
D. Plunger screw is not adjusted properly. Adjust screw using depth guide.
3. Flushometer closes off immediately.
A. Urinal piston parts installed in a Closet ushometer. Replace piston with proper Closet piston (1.6 gpf/6.0 Lpf or 1.28/4.8 Lpf).
B. Piston lip seal may be damaged or worn. Replace with new correct gpf/Lpf piston.
C. Plunger screw not set properly. Adjust screw using depth guide.
4. Length of flush is too short (Short Flush).
A. Incorrect piston is installed in Flushometer; for instance, Urinal assembly inside a Closet Flushometer,
or High Efciency assembly inside a higher consumption xture. Determine the ush volume required by the xture and replace with proper gpf/
Lpf piston. Use valve label and markings on xture for reference.
B. Piston lip seal may be damaged or worn. Replace with new correct gpf/Lpf piston.
C. Plunger screw is not adjusted properly. Adjust screw using depth guide.
5. Length of flush is too long (Long Flush) or continuous.
A. Metering bypass hole in piston is clogged. Remove the piston from the valve, slide o ring off lter, and wash under clean running water.
Reposition o-ring before reinstalling piston. Replace piston if cleaning does not correct the problem.
B. Supply line water pressure has dropped and is not sufcient to close the valve. Close shut off sleeve until pressure is restored.
D. Piston is damaged. Replace with new proper gpf/Lpf piston
E. Incorrect Piston is installed in Flushometer; for instance, Closet assembly inside a Urinal ushometer. Determine the ush volume required by the
xture and replace piston. Use valve label and markings on xture for reference.
6. Chattering noise is heard during flush.
A. Reduce ow pressure by turning shut off sleeve clockwise.
CARE AND CLEANING
DO NOT use abrasive or chemical cleaners (including chlorine bleach) to clean Flushometers that may dull the luster and attack the chrome or special
decorative nishes. Use ONLY mild soap and water, then wipe dry with clean cloth or towel. While cleaning the bathroom tile, protect the Flushometer
from any splattering of cleaner. Acids and cleaning uids will discolor or remove chrome plating.
