The supply line coming from under the sink and going to the refrigerator's ice maker is leaking at the cutoff under the sink. I need it to be removed and cut off, as I don't use the ice maker and I just want it gone. A complicating factor is that I don't know if the house's water cutoff works. The replacement may have to be performed with the water running.
I am located on Brockway near Passolt street.
