So, this may darn well be a ridiculous idea but here goes. I was hoping to run a water line to my fridge for the ice maker etc. The fridge is opposite the sink and water supply with a walkway between on either side. So I cant just go through the cabinets. In an effort to avoid going over the attic or into the downstairs ceiling, can I
A, take the transition strip that connects the laminate flooring to the original hardwoods, and run a dado through the underside and place the water line in this dado to pass it across the hallway?
B, or heck could i just pull up one of the boards from the flooring and cut a dado in that and repeat?
If you have a downstairs finished ceiling covering the pipes, you might consider doing something similiar to what you suggested. I have mine run behind cab's and across a narrow space to the fridge, but the space is against the outside wall. I know it is not professional, but it is mine. Heheh, I'll get around to hiding it....someday.
If I used a transission strip across a walkway, I would be careful not cut the dado too deep and leave the wood too thin to provide adequate strength. This may not be a really big concern considering how thin the dado will be and if the strip is firmly attached on both sides along its length. Just something to think about.
