2. Safety Information
Always observe the following safety precautions during installation and maintenance:
- Turn off water supply: Before performing any work on the urinal flush valve, ensure the main water supply to the fixture is completely shut off.
- Wear appropriate personal protective equipment (PPE): This may include safety glasses and gloves.
- Depressurize the system: After turning off the water, flush the urinal to relieve any remaining water pressure in the system.
- Use correct tools: Ensure you have the appropriate tools for the job to prevent damage to the product or injury.
- Professional installation: If you are unsure about any step, consult a qualified plumber.

4. Setup & Installation
This section outlines the steps for replacing the solenoid and piston assembly in an Ultima Selectronic Urinal Flush Valve.
Required Tools:
- Adjustable wrench or channel locks
- Screwdriver (if applicable for cover removal)
- Clean cloth
Installation Steps:
- Shut off Water Supply: Locate the main water shut-off valve for the urinal or the building and turn it off completely.
- Relieve Water Pressure: Flush the urinal to drain any remaining water and relieve pressure in the flush valve.
- Remove Flush Valve Cover (if applicable): If your Ultima Selectronic Urinal Flush Valve has a decorative cover, carefully remove it to access the internal components.
- Disconnect Solenoid Wires: Carefully disconnect the electrical wires leading to the existing solenoid. Note their connection points for reassembly.
- Remove Old Solenoid and Piston Assembly: Unscrew or unclip the old solenoid and piston assembly from the flush valve body. This may require an adjustable wrench. Be prepared for a small amount of residual water.
- Clean Valve Body: Inspect the valve body for any debris or mineral buildup. Clean the area thoroughly with a clean cloth to ensure a proper seal with the new assembly.
- Install New Solenoid and Piston Assembly: Carefully insert the new M970694-0070A assembly into the flush valve body. Ensure it is seated correctly and tighten it securely, but do not overtighten.
- Reconnect Solenoid Wires: Reconnect the electrical wires to the new solenoid, ensuring a secure connection.
- Restore Water Supply: Slowly turn the main water supply back on. Check for any leaks around the newly installed assembly.
- Test Operation: Activate the urinal flush valve to ensure it operates correctly. Observe the flush cycle for proper water flow and shut-off.
- Replace Cover: If a cover was removed, reattach it securely.
5. Operating Instructions
The American Standard M970694-0070A Solenoid and Piston Assembly is an internal component of an automatic urinal flush valve. Once correctly installed, the flush valve will operate automatically as designed by the manufacturer of the Ultima Selectronic system.
- The solenoid receives an electrical signal from the flush valve's sensor.
- This signal activates the solenoid, which in turn moves the piston to allow water to flow through the valve, initiating a flush.
- After a set duration, the solenoid deactivates, and the piston returns to its closed position, stopping the water flow.
No manual operation is required for this specific component.
6. Maintenance
Regular maintenance helps ensure the longevity and proper function of your urinal flush valve system.
- Periodic Inspection: Periodically inspect the flush valve for any signs of leaks or unusual operation.
- Cleaning: If water quality is poor or mineral buildup is observed, the solenoid and piston assembly may need to be removed and cleaned. Refer to the installation steps for removal. Use a mild descaling solution if necessary, and rinse thoroughly with clean water before reinstallation.
- Avoid Harsh Chemicals: Do not use abrasive cleaners or harsh chemicals on any part of the flush valve, as this can damage components.
7. Troubleshooting
If you experience issues with your urinal flush valve after installing the new solenoid and piston assembly, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Urinal does not flush | No power to solenoid; Solenoid wires loose; Piston stuck or obstructed; Water supply off. | Check power supply to the flush valve; Ensure solenoid wires are securely connected; Remove and inspect piston for debris, clean if necessary; Verify water supply is on. |
| Continuous flushing or slow shut-off | Debris in piston assembly; Piston seal damaged; Solenoid not deactivating properly. | Shut off water, remove and clean piston assembly; Inspect piston seal for damage and replace if necessary; If problem persists, the solenoid itself may be faulty. |
| Weak flush | Insufficient water pressure; Partially obstructed piston; Clogged flush valve components. | Check building water pressure; Remove and clean piston assembly; Inspect other flush valve components for clogs. |
| Leakage around assembly | Assembly not tightened correctly; Damaged O-rings or seals; Debris preventing proper seal. | Ensure assembly is securely tightened (do not overtighten); Inspect O-rings/seals for damage and replace if needed; Clean mating surfaces. |
If these steps do not resolve the issue, it is recommended to contact a qualified plumber or American Standard customer support.
