Please see this image under the sink. The owner cannot identify what this hose is and it appears to not be connected to anything. Does anyone know what it is, possibly to an old garbage disposal that is now gone??

I believe it went to provide water to a fridge/ice maker. I had one very similar at my last house. Sometimes they access the water line from under the sink for ease of maintenance. It appears to currently be disconnected though.

    Or, perhaps, for an instant hot water heater or filtered water system at the sink.

    A what heater? :P I wouldn't expect a heater supply to be that small.

    It may also have served a coffee maker.

    Good points. One key is that it routes out behind the sink so it’s going to something elsewhere in the kitchen
