I would like to branch off of the tiny 1/4" copper tubing that supplies my refrigerator with water and connect the branch to a hose timer that will auto-water some plants that I have in the kitchen.
The refrigerator hose is closest to the part of the kitchen where I need the water. There is some more standard 1/2" copper pipe in other parts of the kitchen, but it would be much more difficult to pipe the water from those places.
Wanted to share what I ended up doing:
- Found a 1/4"od compression "T" at Lowes. This allowed me to branch off from the refrigerator line. One thing that I was confused about was that the copper line used for refrigerators is 1/4" od. The "od" means "outer diameter" which is significantly smaller than a 1/4" inner diameter copper pipe.
- Found a 1/4" od compression fitting to garden hose adapter at Lowes. I was surprised that they carry these. People use copper refrigerator line to make chillers a lot, so maybe that's why they carry them?
These two adapters pretty much did the trick.
