A dripping or broken outdoor spigot wastes water, can damage siding, and becomes a burst-pipe risk every winter. The good news: replacing one is a manageable DIY job that requires only basic plumbing skills and a couple of hours. Most homeowners can complete the repair without calling a plumber.

This guide walks through replacing a standard frost-free outdoor spigot from start to finish.

What You Need

• Frost-free anti-siphon outdoor spigot — match the stem length to your wall thickness (4, 6, 8, or 12 inch)
• Push-fit pipe fittings (SharkBite-style) — eliminates the need to solder if your pipe is copper or PEX
• Pipe cutter for copper — for a clean, square cut on the supply stub
• Adjustable wrench and channel-lock pliers
• Teflon (PTFE) pipe thread tape
• Bucket and old towels
• Drill and spade bit (if enlarging the wall hole)

Step 1: Locate and Shut Off the Water Supply

Find the shutoff valve for the outdoor spigot. In most homes, it is inside the basement or crawl space on the pipe feeding the exterior wall where the spigot is mounted. Look for a ball valve (lever handle) or gate valve (round wheel handle) on the cold water supply line running toward that exterior wall.

Turn the valve fully clockwise to close. If you cannot find a dedicated shutoff, close the main house shutoff at the water meter.

Open the outdoor spigot by turning the handle counterclockwise. Let the remaining water drain from the line — this depressurizes the pipe and reduces the mess when you disconnect the spigot.

Step 2: Remove the Old Spigot

Go outside to the spigot. Look at how it is attached to the house:

• Threaded connection: Most frost-free spigots thread directly into a threaded female adapter soldered or glued to the supply pipe. Grip the body of the spigot (not just the handle) with channel-lock pliers. Turn counterclockwise to unthread it. If the spigot has been in place for years, it may be tight — brace the pipe inside the wall with your other hand to avoid twisting the supply pipe.

• Soldered connection: If the spigot is soldered directly to the copper pipe, you will need to cut the pipe. Use a mini pipe cutter to cut the supply pipe 3 to 4 inches back from the wall so you have enough pipe to work with. This is the point where a push-fit fitting becomes the easiest reconnection method.

Remove the mounting screws holding the spigot flange to the exterior siding. Pull the spigot out from the outside. It may take some wiggling — frost-free stems are 4 to 12 inches long and pass through the wall.

Step 3: Prepare the Connection

For a threaded connection: Clean the threads on the pipe stub inside the wall. Wrap 3 to 4 layers of Teflon tape clockwise around the male threads of the new spigot’s threaded end, starting at the tip and working toward the body.

For a cut copper pipe: Use the pipe cutter’s deburring tool (built into the cutter’s back) or a small round file to remove the burr inside the cut pipe end. Wipe the pipe end clean with a dry cloth. If using a push-fit fitting, you’re ready to connect. If soldering, clean the pipe end with emery cloth and apply flux.

Check the diameter of the wall penetration hole. The new spigot stem needs to pass through cleanly. If the hole is too small for the new body or has rotted siding around it, use a spade bit or oscillating tool to widen or clean up the opening.

Step 4: Install the New Spigot

Feed the new frost-free spigot stem through the exterior wall hole from outside. The stem goes in first, followed by the body and flange.

Threaded connection: From inside, align the threaded end with the female adapter on the supply pipe. Thread it in by hand until snug, then use channel-lock pliers to tighten an additional half to three-quarter turn. Do not over-tighten — stripping plastic threads on the adapter is possible with excessive force.

Push-fit connection: Push the supply pipe end into the push-fit fitting already assembled on the spigot’s inlet, or use a separate coupling between the pipe stub and the spigot inlet. You will hear and feel a click when the fitting seats. Pull back gently to confirm the locking ring has engaged.

Mount the flange to the exterior siding using the provided screws or stainless steel screws. For wood siding, pre-drill to avoid splitting. Apply a small bead of exterior caulk around the flange perimeter to seal out water and drafts.

Step 5: Restore Water and Test

Return to the shutoff valve inside and slowly open it. Let the system pressurize for 30 seconds.

Go back outside and check for leaks:

• At the threaded connection or push-fit fitting inside the wall: Look in from both the interior access point and the exterior hole. Any drip here means the connection needs tightening (threaded) or the pipe was not fully inserted (push-fit).
• At the spigot handle stem: A small amount of water at startup is normal as air purges. Persistent dripping around the stem indicates the packing nut needs snugging — use a wrench to tighten the hex nut just behind the handle body one-quarter turn at a time.
• From the spigot outlet when closed: A drip here usually means the new washer or valve seat is not seating correctly. Verify the spigot is fully closed and recheck.

Attach a garden hose and run it briefly to confirm normal flow and no leaks at the hose connection point.

When to Call a Plumber

Consider calling a licensed plumber if:

• You cannot locate the dedicated shutoff valve and the main shutoff is also malfunctioning
• The supply pipe inside the wall shows signs of corrosion, pinhole leaks, or is galvanized steel (which requires different fittings)
• The wall around the spigot penetration has significant rot or damage that needs structural repair before the spigot can be remounted
