My plastic ice maker water hose broke and I decided to switch it to a stainless braided hose. The stainless braided hose needs a larger hole to pass through. While I have access to drill larger holes through the cabinets the tubing also passes behind a dishwasher and range. I'd rather not have to pull the dishwasher out so how can I drill a larger hole while still leaving something I can use to snake the new water line through?
As I was typing my question I had a thought so I'm answering my own question.
My plan is to make a hole at the end of the tubing and tie some cable pulling line (polypropylene string) and snake that through the original holes by pulling out the old tubing.
Next I'll tape or hold down the string so it's away from the hole and drill a hole next to the original hole that's the right size, slightly overlapping the old hole. That will allow me to pass the string from the small hole to the larger one but keep the string far enough away from the drill to keep it from snagging on the bit.
Then I can tie the end of the stainless braided tubing to the line and pull it through.
