Common concerns about technology.
JAL sensor faucets are battery-operated (DC), meaning they are completely independent of your home’s electrical supply. They will continue to function perfectly even during a power outage.
With average usage, the 4xAA alkaline batteries in the control box typically last between 12 and 18 months before needing replacement.
No, but you must be gentle. Wipe the chrome body as usual, but use a soft damp cloth for the Sensor Eye. Do not use abrasive scrubbers on the black sensor window, as scratches can affect detection sensitivity.
Standard sensor taps provide a single temperature (cold or pre-mixed). However, you can install a Temperature Mixing Valve below the counter to set a comfortable warm/cold mix.
The plumbing is standard (half-inch angle valve), but you must ensure you have an electrical socket nearby for the AC adapter. Also, flush the pipes thoroughly before installation to prevent debris from blocking the sensitive solenoid valve.
