Ya I don't have any of those I have 2 normal valves on the cold water linen leading to outside one inside the basement one outside and there is only shut off on my kitchen sink not even on the bathroom. which sucks but at least it's all copper no galvanized anywhere, The thing I don't like if I want to go Pex to fix anything I have to use a Sharkbite "I think" cause I have never seen any type of crimp for going from copper to Pex
edit Holy lee shit slap my ass and call me Shirly there is a little valve on the side of it, I couldn't see it cause it was covered by some pink insulation
You definately need to drain those down then. Honestly, I'd replace them with frost free.
Also, I have personally tested shark bite fittings to nearly 300psi. They are fine when done correctly.
