IMPORTANT NOTE FOR 1.1 GPF
FLUSHOMETERS & REPLACEMENT KITS
Sloan 1.1 gpf/4.2 Lpf ultra-high efficiency flushometers meets all applicable
standards and requirements. However, with low flush volumes it is imperative that
they only be used in conjunction with toilet fixtures and drain line systems designed
to operate with adequate flow rates and volumes in order to effectively eliminate
waste and move it out of the building. It is the responsibility of the user to ensure
both of these conditions are met. Not doing so may void your warranty.
Sloan 1.1 gpf diaphragm and piston kits are designed as a replacement part for
Sloan 1.1 gpf/4.2 Lpf flushometers only. They are not intended to be used as a
means to reduce water consumption in flushometers with higher flush volumes such
as 1.28 gpf/4.8 Lpf or 1.6 gpf/6.0 Lpf or higher. Using this kit in any manner other
than with a Sloan 1.1 gpf flushometer may void your warranty.
NOTE: After December 2021, the Activation, Sensor, and Solenoid Assembly connections were
changed to a pigtail style connector.
*Colors may differ. Consult factory to confirm you have the correct Activation Assembly.
† 0.125 gpf/0.48 Lpf Valve Components (Piston, Main Seat, and Activation Assembly) are NOT
interchangeable with any other flush volume Valves.

Repair Parts and Maintenance Guide
TROUBLESHOOTING GUIDE
TruFlush Sensor Flushometer
Hardwired with Battery Backup
1. Sensor LED Flashes Continuously Only When User Steps Within Range.
A. Unit is in start-up mode; no problem. This feature is active for the first ten (10) minutes of operation.
2. Red Light Blinks Four (4) Times When User Steps Within Range.
A. “AA” Batteries depleted; replace batteries, lithium or alkaline. Ensure batteries are installed with proper polarity (+) and (-). Do not mix old and new batteries or
different types.
B. (Hardwired) Battery Box not connected; connect Battery Box to Sensor Assembly.
3. Valve Does Not Flush; Sensor Not Picking Up User.
A. Verify a urinal Sensor is not used on a closet Valve. Model is marked on rear of Sensor.
B. Range is too short; recalibrate range. Restart the Sensor by holding the Override Button in for 25 seconds, then release the Override Button and step away
for one (1) minute; with power connected, this is considered a Soft Reset.
C. For Hard Reset of Sensor, remove all power connections (battery and hardwire) for one (1) minute. Reconnect power and step away from front of Sensor for 3½
minutes. Then test Sensor activation by standing in front of Sensor for ten (10) seconds, then step away and wait for flush. Test push button.
4. Valve Does Not Flush; Sensor Picking Up Opposite Wall or Surface, or Only Flushes When Someone Walks By.
Red Light Flashes Continuously for First 10 Minutes Even with No One in Front of the Sensor.
A. Verify a closet Sensor is not used on a urinal Valve. Model is marked on rear of Sensor.
B. Range is too long; recalibrate range. Restart the Sensor by holding the Override Button in for 25 seconds, then release the Override Button and step away for
one (1) minute; with power connected, this is considered a Soft Reset.
C. If range needs to be manually shortened, reset the Sensor (follow Step 3B) and stand in front of the Sensor at desired range distance for one (1) minute.
D. For Hard Reset of Sensor, remove all power connections (battery and hardwire) for one (1) minute. Reconnect power and step away from front of Sensor for 3½
minutes. Then test Sensor activation by standing in front of Sensor for ten (10) seconds, then step away and wait for flush. Test push button.
5. Valve Does Not Flush Even After Sensor Recalibration.
A. Ensure water supply to Valve is turned on.
B. Activation Assembly sleeve is in closed position. Turn counter-clockwise to open water flow. Note: there is approximately 1/8-turn (45°) of free spinning as the
Activation Assembly engages the Shut Off Sleeve between opening and closing the Valve.
C. Solenoid wire disconnected from Sensor. Ensure Solenoid wires are intact and Solenoid plug is connected properly.
D. “AA” Batteries depleted; replace batteries, lithium or alkaline. Ensure batteries are installed with proper polarity (+) and (-). Do not mix old and new batteries or
different types.
E. Sensor Assembly malfunctioned. Disconnect power for one (1) minute, reconnect power, and check for start-up operation (flashing red LED). See Step 4D.
F. Check Solenoid for activation (clicking noise when pressing Sensor Override Button). If no clicks are heard, then contact Technical Support.
6. Valve Does Not Shut Off.
A. Ensure Solenoid is connected to Sensor.
B. Supply line water pressure has dropped and is not sufficient to close the Valve. Close Activation Assembly until pressure is restored.
C. Piston Filter Screen is clogged, Piston is damaged, or large debris stuck behind Piston. Turn off water at Shut Off Sleeve, release pressure, remove Safety Collar
and Activation Assembly. Remove Piston and check inside Valve for large debris. Do not attempt to remove Piston filter screen. Replace Piston if damaged or
cleaning does not correct the problem.
7. Too Much Water To Fixture.
A. Excessive flow pressure. Readjust Activation Assembly by turning clockwise to decrease flow pressure.
B. Long Flush. Worn Piston; replace with new proper gpf/Lpf Piston.
C. Wrong model installed; i.e., 1.6 gpf/6.0 Lpf model installed on 0.5 gpf/1.9 Lpf or 0.25 gpf/1.0 Lpf urinal fixture. Replace with proper model per guide.
8. Not Enough Water To Fixture.
A. Insufficient flow pressure. Readjust Activation Assembly by turning counter-clockwise to increase flow pressure.
B. Water supply pressure is inadequate (low). Increase the water supply pressure. Contact the fixture manufacturer for minimum water supply requirements of the
fixture.
C. Wrong model installed; i.e., 0.5 gpf/1.9 Lpf urinal installed on a 1.6 gpf/6.0 Lpf closet fixture. Replace with proper model.
D. Check lip seal for wear. Replace Piston if lip seal is worn or twisted.
9. Chirping Noise Is Heard At Start Or End Of Flush.
A. Caused by air purging from the system inside the Valve Assembly. Noise will subside with several flushes or within a day.
10. Valve Leaks Through Aspirator When Activated.
A. Debris between the umbrella Valve and the Retainer. Blow air on the Aspirator. If this does not correct the problem, remove Retainer with 5 mm Allen Key (not
included) and wash it under clean running water. Replace Aspirator if cleaning does not correct the problem.
B. Loose Retainer. Hand tight Retainer with 5 mm Allen Key (not included). Do not overtighten. Replace Aspirator if this does not correct the problem.
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
finishes. Use ONLY mild soap and water, then wipe dry with a clean cloth or towel. If using a cleaner in a spray bottle, DO NOT spray directly onto the Flushometer,
instead spray cleaner into a clean cloth and then wipe down the Flushometer.
While cleaning bathroom tile, protect the Flushometer from any splattering of cleaner. Acids and abrasive cleaning fluids will discolor or remove chrome plating.
