Can’t argue with any of that. I’ve had a frost-free faucet freeze up too, just because I forgot to disconnect the hose. Cost me a couple hundred bucks and a weekend fixing drywall. I always shut off the inside valve now and leave the outside one open, even if it feels like overkill. One thing I’d add—pipe insulation sleeves are cheap and easy, but only help so much if there’s airflow, like you said. I’ve used old towels in a pinch too... not pretty but better than a busted pipe at 2am.

Leaving the outside valve open is fine, but I’d argue it’s not always necessary if your frost-free faucet is installed with the right pitch and you remember to disconnect the hose. Those towels might help in a pinch, but they can hold moisture and actually make things worse sometimes. Pipe insulation’s only as good as the air sealing—if there’s a draft, you’re still at risk.
I get where you’re coming from, but I’ve seen frost-free faucets freeze even with the right pitch—sometimes the wall insulation just isn’t up to snuff, or there’s a hidden draft you’d never notice. Disconnecting the hose is huge, but I still tell folks to play it safe and crack the valve if temps are really dropping. Towels always seemed like a last-ditch thing to me... more for peace of mind than real protection.
Yeah, I’ve seen those “frost-free” faucets freeze up too, especially in older houses where the insulation is more wishful thinking than reality. Disconnecting the hose is non-negotiable, but I’m with you—sometimes even that’s not enough if there’s a sneaky draft or the wind’s just right. I’ve tried the towel trick a couple times when I was desperate, but honestly, it always felt like putting a Band-Aid on a broken leg.
One winter, I thought I’d done everything right and still woke up to Niagara Falls in my basement at 3 AM. Turns out there was a tiny gap in the rim joist letting cold air blast right onto the pipe. Now I’m borderline paranoid about checking for drafts every fall... and yeah, I’ll crack the valve if it’s gonna be stupid cold. Peace of mind is worth a little wasted water compared to another midnight mop-up session.
Cracking the valve is my go-to too, even if it feels a bit wasteful. I’ve also started stuffing insulation scraps around the sill plate where the pipe comes through—looks ugly but keeps the wind out. Funny how one little draft can cause so much chaos...
