Changing an outdoor water spigot is a straightforward home improvement task that most DIYers can tackle. With some basic tools and a little know-how, you’ll have your new spigot installed and working in no time. This comprehensive guide will walk you through the entire process step-by-step.
Introduction
An outdoor water spigot, also known as an outdoor faucet or hose bib, provides access to running water outside your home. It allows you to connect a garden hose, wash cars, fill pools, and more. Over time, spigots can start to leak, drip, or even burst, indicating it’s time for a replacement. Replacing an outdoor spigot involves shutting off the water supply, removing the old unit, and installing a new one. This project can usually be completed in an hour or two.
Below we will cover:
- Reasons to replace an outdoor spigot
- Choosing the right replacement spigot
- Gathering the necessary tools
- Shutting off the water and relieving pressure

After reading this guide, you’ll have the knowledge to confidently replace an exterior water spigot at your home. Let’s get started!
Reasons to Replace an Outdoor Spigot
There are several signs that indicate it’s time to replace your outdoor spigot:
- Dripping or leaking: If the spigot leaks constantly when the water is turned on or leaks even when shut off completely, replacement is needed. Leaks can waste water and cause property damage over time.
- No water flow: If little to no water comes out when the spigot is turned on, there is likely a blockage or internal failure. Replacing the unit is usually easier than trying to repair it.
- Corrosion or rust: Spigots exposed to the outdoor elements can eventually become corroded or rusted. This both reduces function and affects appearance.
- Cracks or burst pipe: During winter freeze-thaw cycles, spigots and attached pipes can crack and split. A burst pipe will require replacement.
- Broken handle or knob: Spigot handles receive a lot of use over the years. If the handle breaks off or no longer turns the water on and off properly, replacing the entire unit is the best solution.
- Upgrading: You may want to upgrade from a basic spigot to one with handy features like a built-in timer, anti-siphon design, or freeze-proof capabilities. Installing a new spigot allows you to get the features you want.
Replacing an old, worn-out, or damaged spigot with a new one restores full water flow and pressure. The new spigot will function properly for many years to come.
Choosing the Right Replacement Spigot
When selecting a replacement outdoor spigot, there are a few factors to consider:
- Anti-siphon design: Code in many areas now requires new outdoor spigots to have a built-in backflow preventer. This anti-siphon device stops contaminated water from siphoning back into your home’s plumbing.
- Frost-proof: In climates where temperatures drop below freezing, choose a frost-proof spigot. This type self-drains after use so water won’t freeze inside the valve.
- Materials: Solid brass or stainless steel spigots hold up best to outdoor elements. Plastic is more prone to cracking over time.
- Style: Decorative spigots come in styles like arched, Victorian, or jet pumps to match your home. Standard spigots are more affordable.
- Special features: Options like soap dispensers, timers, locks, and multi-valves provide added functionality. Choose based on your needs.
Take measurements of the existing spigot’s location on the pipe before shopping. Shut off the water and test fit new units before installation to ensure you get the correct size and fit.
Gathering the Necessary Tools
Replacing an outdoor spigot requires just a few basic tools:
- Adjustable wrenches (at least two) to loosen and tighten connections
- Pipe wrench to grip rounded connections or rusted parts
- Teflon tape to seal threaded joints
- Rag to clean pipe threads
- Flashlight to illuminate the work area
- Bucket to catch draining water
- Garden hose with spray nozzle to test new spigot
You may also need a hacksaw to cut through seized connections or a pipe cutter to shorten extender pipes. Have a garden hose ready to test the new spigot.
Make sure you can easily access the main water shut-off valve for the house. Locate this before beginning.
Shutting Off the Water and Relieving Pressure
The first step in replacing an outdoor spigot is turning off the water supply. Here’s how:
- Locate the main shut-off valve for the home’s water supply. This is usually near the water meter.
- Turn the shut-off valve clockwise until it stops to shut off water to the home.
- Turn on the old spigot to allow water to drain out of the pipes. Let it run for a few minutes.
- Attach a hose and spray nozzle, then spray it around the yard to relieve any remaining pressure in the pipes.
- Turn off the old spigot once water flow stops. The pipes are now depressurized and ready for spigot replacement.
If you have shut-off valves specifically for outdoor spigots, you may be able to isolate the water supply without shutting off the entire house.
Removing the Old Spigot
With the water supply disconnected, you can now remove the old spigot:
- Use an adjustable wrench or pliers to loosen and disconnect any hoses or attachments from the spigot.
- Check for a set screw or hex nut holding the spigot handle in place. Remove this if present.
- Use wrenches to loosen and unthread the hex nut connecting the spigot tailpiece to the pipe. Unscrew counterclockwise.
- Twist the spigot handle to help break it free if needed. Apply penetrating oil on stubborn connections.
- Place a bucket under the spigot to catch any water still in the pipe.
- Fully unscrew the spigot tailpiece to remove the old unit. Check the condition of the pipe threads.
- Use a wire brush or steel wool to scrub off any grime, corrosion, or old plumber’s putty from the threaded pipe end.
- Examine the pipe. If it is cracked or damaged, the affected section will need replacement.
Now the pipes are ready for the new spigot installation.
Installing the New Spigot
Once the old unit is removed, installing the new spigot takes just a few steps:
- Wrap the new spigot’s tailpiece threads with 2-3 layers of Teflon tape. This seals the connections.
- Apply plumber’s putty around the new spigot base if necessary to seal any gaps with the wall surface.
- Thread the new spigot tailpiece clockwise onto the water pipe. Hand tighten initially.
- Position the spigot handle and spout as desired before tightening fully. Ensure it aligns properly.
- Use wrenches to tighten the connecting nut until snug. Don’t overtighten.
- If present, install any clips or screws to hold the spigot handle in place.
- Attach any additional garden hose adapters, backflow preventers, or extensions needed.
- Confirm alignments are correct. Tighten any loose connections. Test that the handle opens and closes the spigot properly.
The new spigot is now installed! Next we’ll turn on the water supply and test for leaks.
Turning the Water Back On and Checking for Leaks
With the new spigot installed, restore water service:
- Turn on the main water supply shut-off valve to restore flow to the home.
- Slowly turn on the new outdoor spigot. Check for leaks at connections. Tighten if needed.
- Let the spigot run for a few minutes to flush any debris in the pipes from the install process.
- Fully open the handle to test water pressure through the new spigot. Flow should be strong.
- Attach a hose and spray nozzle to verify proper operation. Test at both high and low flows.
- Walk around the home and check for leaks at other spigots, valves, or pipe connections that may have been disturbed.
If leaks are present, turn off the water and tighten joints as needed. Small drips may seal themselves once pressure is restored. Persistent leaks will require tightening the fittings further or re-applying thread tape.
Winterizing and Maintaining Your New Outdoor Faucet
To keep your new outdoor spigot working properly:
- In cold climates, shut off and drain spigots in winter to prevent freezing pipe damage. Consider installing frost-proof sillcocks.
- Disconnect hoses when not in use. Install backflow prevention devices.
- Check for leaks or drips and repair as soon as noticed to prevent water waste.
- Lubricate stem packing yearly so the handle operates smoothly.
- Avoid forcing the handle or overtightening attachments.
- Keep exterior pipes and valves insulated in very cold weather.
- Caulk around wall plates to prevent air and water intrusion.
Replacing a faulty exterior spigot with a new, high-quality unit will restore optimal water flow for safe use. Follow this guide to complete this project yourself and enjoy your home’s outdoor water supply for years to come.
Frequently Asked Questions About Replacing Outdoor Spigots
Here are answers to some common questions about replacing exterior water spigots:
Do I need a plumber to replace an outdoor spigot?
In most cases, you do not need a plumber to replace an outdoor spigot. This is a straightforward DIY project for many homeowners. If you are uncomfortable working with plumbing, lack the proper tools, or the existing spigot configuration is complicated, hiring a pro can be beneficial.
Where is the shut-off valve for an outdoor spigot?
For a single exterior spigot, the shut-off is typically located inside the house near where the water line exits. For multiple spigots, there may be a dedicated shut-off valve outside near the spigot itself. The home’s main water shut-off valve can also be used.
How do I remove an old rusted spigot?
Apply penetrating oil and let it soak in for maximum effectiveness. You may need to tap the wrench or pliers with a hammer to help break the rust seal. Heat also helps break the bond. If needed, use a hacksaw blade to cut through hopelessly seized connections.
What kind of pipe is best for an outdoor spigot?
Copper is ideal for durability, but galvanized steel and CPVC plastic pipes also work well. Ensure the replacement spigot fits the existing pipe material and size. Use adapters if needed.
How do I stop my outdoor spigot from freezing in winter?
Use a frost-proof sillcock spigot designed to self-drain after use. Insulate pipes and valves. Disconnect hoses. Shut off and drain water supply to spigots. Consider installing heat tape. Avoiding spraying water on frosty nights.
Why does my new spigot have low water pressure?
Ensure shut-off valves are fully open. Disconnect and check the aerator screen for debris clogs. Consider replacing pipes with larger diameter if pressure drop is severe. Rust accumulation in pipes can also restrict flow over time.
How do I tighten a loose spigot handle?
