Did a DIY install of this faucet replacing an older manual Moen that was out of production and I could no longer get parts for. I also ordered the ac adapter kit and installed a GFCI outlet in the sink cabinet to support that. The hardest part was removing the old faucet as space is pretty tight under the sink. Install of the touchless was much easier. Hooked everything up and carefully turned the supply valves back on and ran it through the checkout steps. Everything worked perfectly!
