I've never installed any plumbing before, but I'm going to try to install an outside faucet/sillcock because it seems fairly simple. The only interesting part is that the pex tubing will be run under a crawl space that gets extremely cold in the winter months.
I'm going to use a shut-off valve that can be drained, but I'm not sure the best way to pitch the pex tubing across such a long distance. I was going to use simple talon clamps.
Do I really even need to worry too much about the pitch?
