Sensor faucets use an infrared or ultrasonic sensor to detect movement near the faucet and automatically turn the water on and off without requiring physical contact. The advanced technology allows for hands-free operation that can help prevent the spread of germs while making access to water easier. They first gained popularity in public washrooms but are now commonly found in homes as well.
How they Work
All sensor faucets use some type of motion detection to trigger the flow of water. Infrared faucets detect changes in infrared light near the faucet, while ultrasonic models detect sound waves. When movement is sensed within a few inches of the faucet spout, a small electromagnetic valve will open to allow water to flow. Once movement stops being detected, the valve will close automatically after a preset duration, usually around 6-8 seconds. This ensures water isn't left running without purpose. Sensor technology has advanced greatly in recent years, allowing modern faucets to reliably start and stop the flow of water with bare minimum chances of false detections.
Benefits
The hands-free operation of them provides some clear benefits over traditional Sensor Faucet models:
- Convenience - Not having to physically touch the faucet handle makes access to water much simpler, especially for those with limited mobility or who have their hands full.
- Hygiene - They eliminate the need to touch surfaces in public areas, helping reduce the spread of germs. This is a major advantage in high-traffic commercial washrooms.
- Water efficiency - By stopping the flow of water automatically instead of relying on manual turning off, sensor faucets help conserve water that may otherwise be left running by accident or oversight. This can provide significant water savings over time.
- Lower maintenance - Since there are no faucet handles to break or leak, sensor models generally require less maintenance and repair down the road compared to traditional designs.
Types
While the underlying technology is similar, sensor faucets come in different types suitable for various applications:
- Kitchen faucets - Designed for use over kitchen sinks. Models are available in both pulldown and pullout designs for maximum flexibility and reach.
- Bathroom faucets - Made for lavatory basins, these compact wall-mounted faucets use small sensors. Dual-function models include sensor operation for cold water and a lever for hot water control.
- Commercial faucets - Heavily-built models designed for high usage in public washrooms. Often have vandal-resistant materials and longer automatic shut-off times up to 60 seconds.
- Non-touch urinal and toilet flushers - Use sensors to allow flushing without physical contact with handles or buttons. Ideal for creating touchless restrooms.
Factors to Consider When Buying a Sensor Faucet
While sensor faucets have gained popularity for their convenience, some factors need to be weighed depending on individual needs and use case:
- Durability - Commercial-grade models suitable for high-traffic use may cost more but last longer. Residential faucets need to withstand typical home use.
- Sensor range - The effective detection range varies between models. Ensure it is suitable for the installation space available.
- Water flow - Options include high, low or adjustable flow rates. Consider flow needs and local regulations.
- Temperature control - Methods differ, from levers to touchpads. Choose what's easiest to use and adjust.
- Battery vs hardwired - Battery-powered faucets are portable while hardwired models won't need replacements.
- Warranty - Compare manufacturer warranties which typically range from 5-25 years.
- Price - They often cost more initially but provide value over time through water/energy savings. Determine budget constraints.
Installation Considerations
Proper installation is important for it to perform as intended over many years:
- Compatibility - Ensure model is compatible with existing water supply lines and hole size/configuration.
- Mounting location - Mount per manufacturers instructions, avoiding direct sunlight or heating/cooling vents that could interfere.
- Power requirements - For hardwired models, an electrician may need to run new circuits if no existing receptacle/switch available.
- Water pressure - Most function from 30-125 PSI but consult specs for your local municipal water pressure.
- Batteries - Install new high-quality batteries promptly per manual if using a battery model.
- Adjustment - Calibrate motion sensors and flow/shutoff settings during setup for optimal activation.
- Sealant - Apply thread sealant on water connections before tightening to avoid future leaks.
With proper installation, most sensor faucets deliver years of dependable service enhancing both hygiene and sustainability in homes and commercial spaces alike. The advanced touchless technology improves the overall bathroom and kitchen experience.
