Setup and Installation
Proper installation is crucial for the performance of your new aerator. Follow these general steps carefully.
Tools Required:
- Adjustable wrench or aerator removal tool (if existing aerator is tight)
- Soft cloth
Installation Steps:
- Turn off Water Supply: Locate the shut-off valves under your sink and turn them clockwise to stop the water flow to the faucet.
- Remove Existing Aerator: Grasp the existing aerator and turn it counter-clockwise to unscrew it. If it is too tight, use an adjustable wrench with a soft cloth to prevent scratching the faucet finish.
- Clean Faucet Spout: Thoroughly clean any debris or mineral buildup from the inside of the faucet spout threads to ensure a proper seal.
- Install New Aerator: Insert the GROHE 13952000 aerator into the faucet spout. Turn it clockwise by hand until it is finger-tight.
- Tighten (Optional): If necessary, use an adjustable wrench with a soft cloth to gently tighten the aerator an additional quarter turn. Do not overtighten, as this can damage the aerator or faucet threads.
- Restore Water Supply: Slowly turn the shut-off valves counter-clockwise to restore water flow. Check for leaks around the aerator. If leaks occur, gently tighten further or re-check installation steps.
Operating Instructions
Once installed, the GROHE 13952000 aerator operates automatically with your faucet. It is designed to mix air with the water stream, providing a smooth, splash-free flow while conserving water. No specific user interaction is required for its operation beyond normal faucet use.
Maintenance
Regular maintenance helps prolong the life and efficiency of your aerator, ensuring consistent water flow and preventing mineral buildup.
Cleaning:
Over time, mineral deposits (limescale) can accumulate in the aerator, reducing water flow and affecting the spray pattern. To clean:
- Remove Aerator: Follow steps 1 and 2 from the "Setup and Installation" section to safely remove the aerator.
- Soak: Submerge the aerator in a solution of equal parts white vinegar and water for approximately 30 minutes to an hour. For stubborn deposits, a soft brush (like an old toothbrush) can be used to gently scrub away residue.
- Rinse: Rinse the aerator thoroughly under clean running water to remove all vinegar solution and loosened deposits.
- Reinstall: Reinstall the aerator by following steps 3-6 from the "Setup and Installation" section.
Important: Avoid using abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the chrome finish and internal components of the aerator.
Troubleshooting
If you encounter any issues with your GROHE 13952000 aerator, refer to the following common problems and solutions:
Reduced Water Flow:
- Cause: Mineral buildup or debris in the aerator.
- Solution: Clean the aerator as described in the "Maintenance" section.
Leaking Around Aerator:
- Cause: Aerator is not tightened sufficiently, is cross-threaded, or the washer is damaged/missing.
- Solution: Remove the aerator, inspect the washer for damage, ensure threads are clean and aligned, then reinstall and tighten properly. Do not overtighten.
