1. No Flush
If your Sloan automatic flush system fails to activate, you won’t hear the satisfying sound of a proper flush. This can be indicative of several issues, such as low battery power, a blocked sensor, or water supply problems.
Fix:
- Inspect the sensor for any obstructions, like dirt or tissue, that may affect its motion detection ability. Clean the sensor thoroughly.
- Replace the batteries if the flush seems weak or absent.
- Ensure the sensor is properly aligned to detect users accurately. Check for any blockages in the water supply line.
2. Continuous Flushing
Experiencing an unending stream of water can be frustrating and wasteful. This problem may arise from a stuck solenoid valve, a malfunctioning sensor, a compromised diaphragm, or high water pressure.
Fix:
- Inspect the solenoid valve for debris or buildup; clean or replace it if necessary.
- Ensure the sensor is aligned correctly for optimal flushing timing.
- Check the sensor for wear and replace it if damaged.
- Verify that water pressure is within the recommended range (40-60 psi) and install a regulator if needed.
- Clean the diaphragm to remove any blockages, replacing it if necessary.
3. Water Leakage Around The Valve
Water leakage can often be traced back to the seals or connections around the flush valve. Inspect for wear, damage, or improper installation.
Fix:
- Tighten any loose components to ensure a watertight seal.
- Replace worn-out gaskets and seals to restore integrity.
- Install a new diaphragm if necessary.
- Check the valve body for damage and replace it if needed.
- Refer to the installation manual to confirm proper setup.
- Conduct regular maintenance to prevent future leaks.
4. Flushing At Inappropriate Times
If your flush valve activates unexpectedly, you may be facing calibration issues or sensor interference. Software glitches may also contribute to this problem.
Fix:
- Adjust the sensor’s sensitivity and range following the manufacturer’s guidelines.
- Identify and eliminate any environmental interferences, such as nearby electronic devices or bright lights.
- Check for available updates for the flush valve software or firmware.
5. The Flush Valve Not Resetting After Flush
A flush valve that does not reset can lead to continuous flushing, wasting water and causing frustration. Begin by checking the batteries and inspecting the reset mechanism.
Fix:
- Replace depleted batteries.
- Repair or reset the malfunctioning reset mechanism.
- Clear any debris from the valve to ensure proper function.
- Clean the sensor and adjust its range to optimize performance.
- Replace a faulty solenoid if necessary.
6. Unusual Noises During Flush
Sounds like rattling or vibrating during a flush may indicate issues with internal components. This could stem from a damaged cover or loose connections.
Fix:
- Replace any damaged inner covers or diaphragm assemblies.
- Clean the valve to remove sediment build-up.
- Tighten all loose nuts and bolts to eliminate noise sources.
7. Short Flush
A short flush can fail to effectively remove waste, leaving remnants behind. This issue might be due to a worn diaphragm assembly or a clogged flush valve.
Fix:
- Replace the diaphragm assembly.
- Thoroughly clean the flush valve to ensure it operates effectively.
- Inspect the reset mechanism for issues and repair or replace as necessary.
8. Incomplete Flush
An incomplete flush typically results from blockages or low water levels hindering the flow. Inspect the flush valve and water pressure for potential issues.
Fix:
- Clean the flush valve to remove any debris.
- Ensure water pressure is maintained at the appropriate levels.
- Replace worn components of the flush valve to restore functionality.
Why Is My Sloan Automatic Flush Valve Blinking Red?
A red blinking light usually signals low battery power or a sensor issue. Replacing the batteries may resolve the problem. Additionally, ensure the sensor is clean and free from obstructions to enhance its detection capabilities.
How To Change Batteries on A Sloan G2 Flushometer
The battery compartment for the Sloan G2 Flushometer is conveniently located on the top of the valve cover. Follow these steps to change the batteries:
- Loosen the screws on top of the unit and remove the cover.
- Disconnect the wire clip from the battery compartment and remove the cover.
- Take out the old batteries and replace them with new ones.
- Reattach the battery compartment cover and tighten the retaining screw to ensure a good seal.
- Reconnect the sensor module before replacing the cover and tightening the screws.
Note: The Sloan G2 Flushometer will signal low battery status by flushing a red light four times when a user approaches the urinal.
