Thanks SuperD for the suggestion. Pulled out the back & bottom panels under the sink. Found what I believe was the “kinked” hose causing the leak when opening and closing the slide and rerouted to avoid “kinkage”. At the same time, I removed the extra 5 feet of heater ducting the factory left on and switched the sink hot and cold water supplies to where they should have been to start. Three repairs in one location! Thanks Thor.
Happy New Year’s to all of you.
