Add spicket in garage in cold weather climate
I plan to add a spicket in our garage and use it, mainly, for washing our cars. It will be plumbed to soft-water. We live in a cold weather climate but the wall I intend to install it on is an interior wall (between the garage and the house... the garage is attached to the house).
I know I can get a frost-free (or something like that... the name escapes me right now) spicket that has a larger diameter tube from 8" to 12" long and is supposed to help prevent freezing. I'm wondering if that is necessary in this case since the spicket is not outdoors nor on an exterior wall. Is this the best idea or are their good alternatives?
I plan to tap into my existing copper pipe and use PEX tubing. I'm a little hesitant to do this as I've only every used copper before and the PEX stuff makes me a bit nervous. Any thoughts on that?
Other thoughts or advice? Thanks in advance.
