Winterize Outdoor Water Spigots Before the Freeze

Cold weather can turn a small outdoor faucet leak into a costly plumbing repair. When water remains inside a hose bib, supply line, or attached garden hose, freezing temperatures may cause the water to expand and split the fixture or pipe. The damage can stay hidden until spring or until thawing water enters walls, crawl spaces, or utility areas.

Preparing exterior faucets is especially important in Susanville, where overnight temperatures can fall below freezing during the colder months. A few steps taken before a hard freeze help protect household plumbing, reduce water waste, and keep outdoor fixtures ready for the next growing season.

The City of Susanville Public Works Department provides municipal infrastructure and utility information for local residents. Its resources can help households find relevant guidance for water service, conservation, billing, and public works concerns.

Why Outdoor Faucets Need Winter Protection

A connected hose can trap water inside the spigot and the short section of pipe behind it. If that water freezes, pressure may build between the ice and the closed indoor shutoff valve. The faucet body may crack, or a pipe connection inside the building may fail.

Frost-free hose bibs offer added protection because they are designed to shut off water farther inside the insulated structure. They still require proper installation and a downward angle that allows water to drain. A hose, spray nozzle, or other attachment left connected can prevent drainage and reduce the fixture’s freeze resistance.

Before winter arrives, inspect each outdoor water outlet, including hose bibs near garages, sheds, workshops, and additions. Look for dripping valves, cracked handles, loose fittings, mineral buildup, and signs of dampness around the wall. Small defects should be repaired before temperatures drop.

Find and Test the Indoor Shutoff

Many exterior faucets have a dedicated indoor shutoff valve on the supply line. It may be located in a basement, crawl space, utility room, garage, or near where the pipe passes through an exterior wall. Some valves include a small bleeder cap that allows trapped water to drain after the valve is closed.

Turn the indoor shutoff clockwise until it is fully closed, without forcing it. Then open the outdoor faucet and leave it open so water can drain from the exposed section of pipe. If the valve has a drain cap, place a container beneath it and open the cap carefully.

After draining, close the bleeder cap and leave the outdoor faucet slightly open if the fixture design allows. Check for continued water flow. A steady stream may indicate that the shutoff valve does not close completely and needs maintenance from a qualified plumber.

Match the Method to the Fixture

Different outdoor plumbing arrangements need slightly different preparation. The following guide provides a practical starting point for common residential fixtures.

Outdoor fixture or condition	Winter preparation	Additional protection
Standard hose bib with indoor shutoff	Remove the hose, close the indoor valve, open the faucet, and drain the line	Add an insulated faucet cover after drainage
Frost-free hose bib	Remove all attachments and confirm the faucet slopes downward	Use a cover only if it does not block designed drainage
Faucet without a known indoor shutoff	Disconnect the hose and drain the faucet thoroughly	Arrange an inspection before severe cold
Outdoor branch line serving irrigation	Shut off the supply and follow the system’s blowout or drain procedure	Protect backflow devices and exposed valves
Faucet that drips after shutoff	Do not rely on insulation alone	Repair or replace the faulty valve
Exposed pipe in an unheated space	Close the supply, drain the line, and insulate the pipe	Keep insulation dry and seal drafts around openings

Insulation slows heat loss; it does not remove water from a pipe or replace a working shutoff valve. Covers are most effective when installed over a dry, disconnected faucet after the supply has been closed and drained.

Complete the Winterization Steps

Start by removing garden hoses, timers, splitters, pressure washers, and spray attachments. Drain each item before storing it in a protected area. A connected accessory can hold water against the faucet and allow freezing pressure to develop.

Next, close the indoor shutoff and open the exterior faucet. Let the line drain fully, then check the opening for residual water. If the faucet continues to run for more than a short period, close it and investigate the shutoff rather than assuming the line is empty.

Install a purpose-made insulated faucet cover according to its instructions. The cover should fit snugly around the fixture and wall penetration, with no gaps that allow cold air to circulate. Avoid wrapping the faucet in materials that absorb water or obstruct drainage.

In an unheated garage, crawl space, or utility area, inspect the indoor section of the pipe as well. Pipe insulation can reduce heat loss, while sealing drafts around penetrations helps maintain a more stable temperature. Never use an open flame or unsafe heat source near plumbing.

Use a Simple Winter Readiness Checklist

A consistent checklist makes it easier to prepare every outdoor outlet before the first deep freeze. Mark each faucet as it is inspected, especially if a property has multiple buildings or separate water zones.

• Remove and drain every outdoor hose and attachment.
• Locate, close, and test each indoor shutoff valve.
• Open exterior faucets to release trapped water.
• Inspect for leaks, cracks, corrosion, and loose fittings.
• Install suitable insulated covers after drainage is complete.

During a cold spell, check unheated areas periodically for unusual dripping, ice buildup, or damp spots. If a pipe freezes, do not apply a torch or other direct flame. Shut off the water supply if a rupture is suspected and arrange professional service.

Protect Water Service Through the Season

Winter preparation also supports efficient water use. A leaking hose bib can waste water throughout the year, and a split pipe may release a large volume before the problem is noticed. Prompt repairs protect the household plumbing system and help conserve the community’s water supply.

If a frozen or damaged fixture affects municipal service, use local public works resources to identify the appropriate contact or emergency information. Keep shutoff locations accessible, label unfamiliar valves, and record the date each outdoor faucet was serviced.

Complete these steps before the next freeze and inspect the fixtures again when temperatures rise. Early preparation can prevent avoidable damage, preserve reliable outdoor water access, and give Susanville households greater confidence throughout the winter season.
