I’ve seen handle-less faucets before, but never have I seen a screw-in faucet protecter. Must be super-precious water!

My across the street neighbor(same Cole Valley) had a regular pull up and wash his car, I watched him one week!
Ahh, that makes sense. Taking off the handle isn’t always enough, since anyone can buy a faucet key at a hardware store. Heck, I’ve even used my own key to access handle-less faucets!
