Learned my outside faucet froze yesterday when my son tried to wash his car. Water started pouring inside. So today I drilled some holes n stuck my sope inside to see what I'm up against. Well I'm hopeful it's easier that I'm anticipating. Looks like this just screws on to a fitting, but I would like to see if you all could provide some confirmation on this particular unit. What made me realize is that it's not actually screwed into the wall to support it so it must be screwed into a fitting for support. Well here are the pictures, I am guessing when the house was built it was never angled down for draining and held water in the pipe.
