Client called us out today due to the touch less kitchen faucet not working properly. On previous visit, I did notice the battery back for the faucet was being held together by rubber bands, but was working when I left. The battery pack had all fallen apart which is why it wasn’t working. We then found a new kohler single handle kitchen faucet in black finish, then replaced that failed faucet and reconnected back to the water shutoffs. No leaks, operating as it should.
