Last week while trying to unscrew my stick on hose I bent the copper and it broke off.  I have a basic idea of how I will be fixing it but need some advice. 

So what I’m probably going to do because it’s faster and I’ve used it before with no issues is cut off the pipe leaving about 2 inch’s, cleaning it up then using a shark bite sillcock, putting it through the wall from the outside leading into the basement and just attaching it.  

Now here’s my issue. The hole in the wall where the old silllcock came out has a decent amount of wiggle room and the person to install it way better I moved I didn’t close the gap or attach/drilled  the faucet to the outside wall. It kinda just sat in the hole.  

The outside wall is stucco I believe.  I’m not quite sure it sturdy but falling apart a tiny bit.  

My question is. How should I go about doing this. Should I screw the part in the wall  then come from behind  in the basement with like and expansion foam and fill The hole to keep it sturdy and insulated or should I not worry about screwing the faucet to the wall outside  and just use the foam to keep the pipe from moving and call it a day. 

Obviously I know you should screw it in for extra stability But the wall isn’t flush also  I’m worried the wall might just crack. And the drill i have is decent (a RYOBI,   drill  and yes i don’t care I personally love my RYOBI collection of tools lol, ) any way  12  settings of torque and I have a masonry drill bit if needed. 

But if I do screw it in do I need to even pre drill? Or can I just use any screws, and just screw it inOr can I get away by filling the whole gap around the pipe. Also  what should I use to fill the gap?  Will the expansion foam work or should I use like a type of concrete adhesive caulk and fill it with that to keep it sturdy?? 

I’ll be honest when it comes to construction. plumbing  and masonry work is where I lack experience. 

Thanks for not making fun of my RYOBI lol 😂……. anyway any help/advice would be much appreciated. As soon as possible.  Also here is the spillcock I’m using.  Also I just realized the sillcock is brass will that be an issue connecting to copper?  

And if anyone has any better ideas or ways to do it that are easier and less money. Let me know!!

Sillcock replacement advice?
