On today’s visit the customer made me aware that the kitchen sink faucet was not functioning at all and so I investigated the power module below the sink because it is a touch style faucet and found that the low battery light was blinking and would cause the unit not to function at all. I change the batteries six AA for the customer as a courtesy and have restored water to the kitchen sink and of course now everything is functioning properly. I also show the customer how to change the batteries Nick pleasants Cary,nc
