I have a Waste King/Thermador DW and have I’ve been searching for a 40" x 1/4" ID water fill tube (#411752 made by Bosch.) Bosch said it is a discontinued item. I’ve also looked at about 100 dishwasher diagrams on this site to see if something else will work. Part #AP3206810 is close.
Is there any reason why a piece of copper tube of the same dimensions will not work in this application?
