Is Your Outdoor Frost Proof Faucet Leaking? Here’s How to Fix it!
A frost-proof faucet on the exterior of your home (technically called a sillcock, it’s also known as a frost-free or freeze-proof faucet) is similar to a common outdoor faucet. What’s the difference?
The outdoor frost-proof faucet has an extra-long stem (or pipe) reaching back about 12 inches inside the hose. This is one of the keys to its freeze-proof superpowers. But like any other type of faucet, parts do wear out and require periodic replacement. In this case, it’s the stem’s washer.
How to Repair a Leaky Frost-Proof Faucet
Here are step-by-step instructions for how to repair a frost-proof faucet that’s leaking from a worn-out O-ring or washer.
- Turn off the water supply valve to the sillcock inside the house. It should be located somewhere close to the opposite side of the outdoor spigot (on the inside of the house). If you can’t find it, then shut off the main water supply for the entire house. It’s located near your water heater in a basement or utility closet.
- Remove the handle screw. Lift the handle straigh up and off.
- Using an adjustable wrench, remove the hexagonal retaining nut by turning it counterclockwise.
- Turn the stem counterclockwise and pull it all th way out.
- Take the retaining nut and the stem to a hardware store and purchase replacement O-rings and washer.
- Replace the O-rings and washer.
- Insert the stem into the sillcock body and turn it clockwise as far as it will go.
- Screw the nut back on the stem with the adjustable wrench.
- Replace the handle and secure it with the handle’s screw.
- Turn the water supply valve back on and check for leaks . Tighten the retaining nut further if necessary.
Recommended Frost-Proof Faucets
- Anti-Siphon Sillcock Frost-Free Faucet (6, 8, or 12 inches long should suffice)
- Outdoor Faucet Covers (look for a Soft Sock or Hard Shell variety)
Final Thoughts
Trust us, repairing a frost-free faucet looks much more complicated than it actually is.
Remember, all you’re doing is (1) tightening what’s already part of the assembly to make sure the fittings are extra-secure, and (2) replacing simple O-ring and washer if they look worn out. It’s as simple as taking one out and putting the new one in. Give it a try if you’re seeing a leak. You got this!
