Installation Instructions
These instructions outline the general procedure for replacing the solenoid. Specific faucet models may have slight variations. Refer to your faucet's original manual for detailed disassembly steps if needed.
- Prepare the Faucet:
- Locate the main water supply valves for the faucet (typically under the sink) and turn them completely OFF.
- Open the faucet handle to drain any remaining water and relieve pressure in the lines. Ensure no water is flowing.
- Access the Solenoid:
- Depending on your specific Moen M-POWER faucet model, you may need to remove access panels or components to reach the solenoid valve. This often involves disassembling parts of the faucet body or control box.
- Carefully disconnect any electrical connectors attached to the existing solenoid. Note their orientation for reassembly.
- Remove Old Solenoid:
- Unscrew or unclip the old solenoid from its housing or manifold. Be prepared for a small amount of residual water to drain.
- Inspect the area for any debris or mineral buildup and clean as necessary.
- Install New Solenoid:
- Carefully insert the new Moen 174056 solenoid into the designated position. Ensure it is seated correctly and securely.
- Tighten any screws or clips to secure the solenoid. Do not overtighten.
- Reconnect the electrical connectors to the new solenoid, ensuring a firm connection.
- Test and Reassemble:
- Slowly turn the main water supply valves back ON.
- Check for any leaks around the newly installed solenoid.
- Test the faucet's operation to ensure the solenoid is functioning correctly (e.g., water flow starts and stops as expected).
- Once confirmed, reassemble any removed access panels or faucet components.
Operating the Faucet (After Solenoid Replacement)
The Moen 174056 Solenoid Repair Kit restores the proper function of your Moen M-POWER commercial faucet. The operation of the faucet itself remains unchanged. Depending on your specific M-POWER model, operation typically involves:
- Sensor Activation: For sensor-activated faucets, water flow will begin when hands are detected within the sensor's range and stop when hands are removed.
- Manual Activation: For models with a manual override or push-button activation, water flow will be controlled by these mechanisms.
The solenoid is responsible for opening and closing the water flow in response to the faucet's electronic controls.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your Moen faucet and its components, including the solenoid.
- Cleaning the Faucet Finish: To preserve the finish on the metallic parts of your Moen faucet, apply non-abrasive wax, such as car wax. Any cleaners should be rinsed off immediately. Mild abrasives are acceptable on Platinum and LifeShine® finishes. Avoid harsh chemicals or abrasive cleaning tools that can damage the finish.
- Regular Inspection: Periodically inspect the solenoid and its connections for any signs of wear, leaks, or corrosion. Address any issues promptly.
- Water Quality: In areas with hard water, mineral buildup can affect solenoid performance. Regular flushing of the lines or professional descaling may be beneficial.
