Why You Should Turn Off Your Outdoor Water Spigot in Winter

Turning off your outdoor water spigot before the first hard freeze is one of the cheapest, fastest ways to protect a New Jersey home from a burst pipe. In 27 years of restoring water-damaged homes across all 21 NJ counties, I have seen the same December emergency again and again: a hose left on, a valve left open, and a wall full of water once the temperature swings back above freezing. This guide walks you through exactly why it matters and how to winterize your spigot correctly.

Why turning off your outdoor water spigot matters in New Jersey

New Jersey winters rarely stay cold. We get freeze-thaw cycles — a bitter night in the teens followed by a 40-degree afternoon — and that swing is exactly what breaks pipes. Water trapped in an exposed spigot line freezes overnight, expands, and cracks the pipe. You often will not know anything is wrong until the thaw, when water starts pouring out of that crack and into the wall cavity behind the faucet.

Frozen and burst pipes

Outdoor spigots are usually fed by pipes that run through an exterior wall, the least insulated part of your home. When water sits in that line during a freeze, it expands with enough force to split copper or PVC. A hairline crack is all it takes. The moment the ice thaws, that crack becomes an open tap running inside your wall.

Hidden water damage

A burst supply line can release hundreds of gallons before anyone notices, because the leak starts inside the wall. That water soaks drywall, insulation, framing, and flooring. Left even a day or two, it invites the kind of structural damage and mold growth that turns a $0 prevention step into a major restoration project. If it has already happened, our water damage restoration team can extract, dry, and rebuild.

Avoidable repair costs

Shutting a valve and pulling a hose costs nothing. Repairing a burst pipe plus the water damage behind it is a different story — and the mold that follows a slow, unnoticed leak is worse. Because we bill insurance directly, most of our storm and freeze customers are surprised how much of a covered loss is handled without out-of-pocket stress, but avoiding the claim entirely is always cheaper than filing one.

How to shut off and drain your outdoor spigot

Winterizing an outdoor water spigot takes about ten minutes and no special tools. Do this before the first sustained freeze — in most of New Jersey that means by mid-to-late November.

1. Locate the interior shut-off valve. Most spigots have a dedicated shut-off inside the home — usually in the basement, crawlspace, or utility area on the wall directly behind the outdoor faucet.
2. Close the valve completely. Turn it fully clockwise to stop water flow to that spigot. If the valve has a small bleeder cap, keep it handy for the next step.
3. Open the spigot outside. Go outside and open the faucet. This drains the water still sitting in the line so there is nothing left to freeze and expand. Let it run until it stops dripping, then leave it open through winter.
4. Disconnect every hose. Remove hoses, splitters, and timers. A connected hose traps water against the faucet and is one of the most common causes of a frozen, cracked spigot.
5. Add an insulated cover. A foam faucet cover or insulated dome adds a cheap layer of protection, especially for spigots on a north-facing or wind-exposed wall.

If you have a frost-free spigot, you still need to disconnect the hose — a hose defeats the frost-free design by holding water in the faucet where it can freeze.

Winterizing the rest of your plumbing

The spigot is the highest-risk fixture, but it is not the only one. While you are at it:

• Insulate exposed pipes. Foam pipe sleeves on lines in the garage, crawlspace, and along exterior walls cost a few dollars and prevent freezes indoors, too.
• Know your main shut-off. If a pipe does burst, being able to kill the water at the main in seconds is the single biggest factor in how much damage you take.
• Keep the heat on when away. Never let an empty house drop below the mid-50s in winter. For a full explanation, see our post on why you should not turn your heat too low over the holidays.
• Watch the forecast. Winterize before the first freeze, not after. A single overnight dip into the low 20s is enough to crack an open spigot line.

What to do if a pipe bursts anyway

Even careful homeowners get caught by a surprise freeze. If you find a burst pipe or water spreading from behind a wall, act fast:

• Shut off the water at the main immediately.
• Cut power to any affected area if water is near outlets or fixtures.
• Move belongings out of the water and start removing standing water if it is safe.
• Call a professional restoration team — the first 24 to 48 hours decide whether this becomes a mold problem.

Frequently asked questions

When should I turn off my outdoor water spigot in New Jersey?

Shut it off before the first sustained freeze — in most of New Jersey that is mid-to-late November. It is always safer to winterize early than to gamble on a warm stretch, since a single night in the low 20s can crack an open spigot line.

Do I still need to drain a frost-free spigot?

Yes. A frost-free faucet keeps its valve inside the warm wall, but a connected hose holds water in the spout where it can still freeze and back up into the line. Always disconnect the hose and let the spigot drain, even on a frost-free model.

What happens if I forget to disconnect the garden hose?

Water trapped in the hose freezes and expands back toward the faucet, cracking the spigot or the pipe behind the wall. A leftover hose is one of the most common causes of a burst outdoor water spigot we see each winter.

How do I know if my spigot pipe already froze or burst?

Warning signs include no water or weak flow from the spigot after a freeze, banging or whistling in the pipes, damp spots or discoloration on the wall behind the faucet, or an unexplained jump in your water bill. If you notice any of these during a thaw, shut the water off and call for help.
