Winterize Your Outdoor Faucets Before You're Standing in a Lake

By HireA.Tech Editorial Team · Published 2026-09-18

First hard freeze is coming. If you're reading this in late October and haven't drained your hose bibs yet, drop everything and do it today. I mean it.

Burst exterior faucets are one of the dumbest service calls I run. Dumb because they're completely avoidable, and dumb because the fix usually costs ten times what prevention would've. A $12 foam cover and ten minutes of your time in autumn beats a $400 plumber visit in January when the line splits inside your wall and you've got water running down through your basement ceiling.

What Actually Happens When You Don't

Water expands about 9% when it freezes. Copper, PEX, even galvanized—none of it cares. The pipe will split. Sometimes right at the faucet, sometimes six inches back in the wall where you can't see it until spring melt. I've cut into walls in March and found ice still sitting in a cracked stub-out.

The forums are full of "burst pipe crumbling" posts right now. It's that time of year. Guys discovering cracks, homeowners who swear they "thought they drained it" but left the hose attached or didn't kill the interior shutoff. It's always the same story.

The Right Way, Not the Fast Way

Shut off the interior valve. Most hose bibs have a shutoff somewhere inside—basement, crawlspace, utility room. It's usually a quarter-turn ball valve or a old-school gate valve. Close it all the way. If you've got a gate valve and it's been sitting open for five years, don't be shocked when it leaks or won't seal. That's a separate problem to deal with now, not in February.

Open the outside faucet and leave it open. This lets any trapped water drain out and gives expanding ice somewhere to go if a little moisture is still in there. Some bibs have a little bleeder cap on the side—crack that open too.

Drain the line. If your shutoff valve has a little brass cap or bleeder screw, open it with a bucket underneath. You'll get a few ounces to a pint of water out. That's the water that was sitting in the pipe between the valve and the faucet. That's what freezes and splits the copper.

Disconnect the hose. I can't believe I have to say this every year, but: take the damn hose off. A hose traps water in the faucet. Even if you drained the line, even if you shut it off inside, a full hose creates a column of water with nowhere to go. It'll freeze and crack the faucet body every time.

Frost-Free Faucets Are Not Actually Foolproof

Frost-free hose bibs (the ones with the long shaft where the valve seat is 6–12 inches back inside the warm wall) are better, but they're not magic. If you leave a hose connected, you've defeated the design. The water can't drain back, and the whole point of a frost-free is that it drains when you shut it off.

I've replaced a dozen frost-free faucets this year alone because someone left the garden hose hooked up all winter. The valve seat cracks, and come spring you've got water running inside the wall. Not a leak you see—just a slow drip that rots out your rim joist until you notice the drywall stain in July.

Insulated Covers: Cheap Insurance

A foam faucet cover from the hardware store runs about $4. Hard plastic clamshell ones are maybe $12. For exposed faucets on the north side of the house or anywhere wind hits, toss one on after you've drained everything. It's not a substitute for draining, but it's a good second layer.

Heat tape is overkill for a faucet that's properly winterized, but if you've got a bad install—short frost-free, exterior wall with no insulation, something stubbed out in a soffit—yeah, a couple wraps of self-regulating heat cable might be the band-aid that gets you through the season. Just don't use it as an excuse to skip the shutoff and drain. Heat tape fails. Then you're relying on a $18 electric cable to keep a pipe from splitting at 2 a.m. on the coldest night of the year.

October Is the Month

You want this done before the first hard freeze. Around here that's mid-to-late October, sometimes early November if we're lucky. I've seen years where we got a freak cold snap in early October and half the neighborhood learned the hard way.

Once daytime highs stop hitting 50°F consistently, you're in the window. If you're seeing frost on your windshield in the morning, you're late. Get it done this weekend.

Interior Prep While You're At It

If you're already thinking about freeze protection, knock out a couple other autumn tasks:

Pipe insulation. Crawlspace lines, pipes running along exterior walls in unheated garages, anything in a zone that might drop below 40°F. Foam sleeves are like $8 for six feet. Slit one side, snap it on, done. I see way too many PEX runs in uninsulated crawls with nothing on them. PEX won't shatter like copper, but it'll still freeze solid and you'll have no water until it thaws.

Water heater flush. Autumn's a decent time to drain a few gallons out of your tank and clear the sediment. Doesn't have to be a whole production—hook a hose to the drain valve, run it outside or into a floor drain, open it up for two minutes, shut it off. You'd be amazed how much crud settles in there. Sediment kills efficiency and eats tanks from the inside. I've cut open 8-year-old water heaters that should've gone 12 and found three inches of calcium and rust sludge on the bottom.

Not going to pitch you a new water heater here—it's not relevant—but if you're looking at commercial gear (multi-family, shop buildings), AERCO just dropped the Benchmark NX line for light commercial. Compact, high-efficiency, built on the same guts as the bigger Benchmark units that actually hold up. Seen those run in apartment complexes for years. Residential guys won't care, but if you're spec'ing a fourplex or a car wash, it's worth a look.

The One Thing That'll Bite You

The shutoff valve inside that hasn't been touched in ten years. You go to close it, it's seized, or it closes but starts weeping at the packing nut, or it won't close all the way and you've got a slow drip you can't stop.

Fix it now. Not in January when it's 12°F outside and you're trying to solder with frozen fingers. A $9 quarter-turn ball valve beats fighting with a 40-year-old gate valve that needs packing replaced or a new seat.

Just Do It

This isn't one of those jobs you can get cute with. No "good enough" version. Either the line's drained and the faucet's open or you're gambling. And the house always wins when water freezes.

I've seen split copper flood a finished basement. I've seen a cracked hose bib drip into a sill plate all winter and cost someone $4,000 in rot repair and mold remediation. Ten minutes of work in October prevents all of it.

Shut it off. Drain it. Disconnect the hose. Put a foam cover on if you want. Move on with your life.
