Hi- I left my hose connected outside and we had a spring freeze and it split the pipe stem attached to the spigot. It looks like it should be a relatively easy repair as it looks to be threaded into the main pipe, but I've tried turning it off and it's not really budging. Should it just screw off? I'm a little afraid to go to hard at it as not to cause other issues. Attached is a pic. Any help is appreciated.
