A leaking outdoor faucet can be a nuisance and lead to higher water bills, property damage, and wasted water. Luckily, most outdoor faucet leaks can be repaired fairly easily if you have the right tools and knowledge. Here is a step-by-step guide for how to fix a leaking outdoor faucet.
Symptoms of a Leaking Outdoor Faucet
Here are some signs that your outdoor faucet may be leaking:
- Water dripping or running from the spout when the faucet is off
- Wet spots or pooling water around the faucet, pipe connections, or foundation
- An elevated water bill
- Low water pressure
If you notice any of these issues, it likely means your outdoor faucet needs repair.
Tools and Materials Needed
Before starting any repairs, make sure you have the following tools and materials on hand:
- Adjustable wrench or pipe wrench
- Silicone lubricant or pipe joint compound
- Replacement washers and o-rings
- Rag or towel
- Flashlight
- Needle-nose pliers
- Screwdriver
- Pipe insulation or heat tape (for cold climates)
Shutting Off the Water Supply
The first step is to turn off the water supply to the leaking outdoor faucet. Locate the shut-off valve for the outdoor faucet line, usually found near where the pipe exits your home. Turn the valve clockwise until tight to shut off the water.
Turn on the outdoor faucet briefly to release any built-up pressure. Once the water is off, you can start taking the faucet apart to inspect it and make repairs.
Taking the Faucet Apart
Start by using a rag or towel to remove any water or debris from the faucet and pipe connections. This makes it easier to access the faucet parts.
Use a wrench or pliers to loosen and remove the faucet handle if there is one. Unscrew the packing nut that holds the stem or cartridge in place, then carefully remove the stem assembly.
Inspect the rubber washers at the base of the stem and at the seat inside the faucet body. Worn, cracked, or improperly seated washers are often the cause of leaks. Carefully remove the washers if you need to replace them.
Replacing Washers and O-Rings
If the existing washers are worn out, simply replace them with new ones of the same size and type. Use silicone lubricant on the washers and seating area to help create a watertight seal.
Make sure the new washers are smoothly seated in place. Double check that any o-rings fit properly in their grooves as well to prevent leaks. Take your time and align the washers correctly as you re-assemble the faucet.
Re-installing the Faucet
Once the washers are replaced, carefully re-install the faucet stem and re-attach the packing nut. Make sure not to over tighten. Then re-attach the faucet handle if there is one.
Before fully turning the water back on, wrap pipe insulation or heat tape around exposed pipes near the faucet. This helps prevent freeze damage during winter.
Slowly turn the water supply back on and check for any drips or leaks around the newly repaired faucet. Tighten any connections if needed. If leaks persist, you may need to further disassemble the faucet and inspect for damage or blockages. Let the water run for a few minutes to clear any debris.
Preventing Future Leaks
To help prevent future leaks:
- Inspect washers and o-rings annually for wear
- Make sure faucet parts are aligned correctly
- Apply silicone lubricant to maintain a watertight seal
- Drain and shut off outdoor faucets before the first freeze
- Insulate exposed pipes and hose bibs
- Replace washers and cartridges as needed
With the proper tools, materials, and maintenance, repairing an outdoor faucet is usually a straightforward process. Catching leaks early and replacing worn parts can help stop the problem before it causes any major property damage. If leaks persist after all repairs, you may need to replace the faucet completely.
Frequently Asked Questions About Fixing a Leaking Outdoor Faucet
How can I tell if I have a leak in my outdoor faucet?
Signs of a leak include water dripping from the spout, wet spots around the foundation or pipe connections, low water pressure, and higher than normal water usage on your meter or bill.
What are the most common causes of an outdoor faucet leak?
Worn out rubber washers and o-rings are the most common causes. Mineral deposits, freeze damage, improper installation, and broken internal parts can also result in leaks.
Should I replace a leaking outdoor faucet or try fixing it?
Try fixing it first by replacing washers and o-rings, which is inexpensive. If the leak persists after repairs, then you likely need to replace the entire faucet.
Is it okay to repair an outdoor faucet while the water is still on?
No, always turn off the water supply via the shut-off valve before taking a faucet apart for repairs to avoid water damage.
How can I prevent my outdoor faucets from leaking during winter?
Insulate exposed pipes and hose bibs near outdoor faucets. Drain and shut off the water supply to outdoor faucets before the first deep freeze.
How often should I replace the washers on my outdoor faucets?
Inspect washers at least annually before winter and replace them as needed. Rubber washers deteriorate over time and should be replaced every few years.
Conclusion
Repairing a leaking outdoor faucet is usually an easy, inexpensive fix. With the proper tools and replacement parts, you can take apart the faucet, replace worn washers and o-rings, and stop the leak in its tracks. Pay attention to shut off the water first, lubricate parts for a good seal, and prevent future wear and tear. Catching and repairing small leaks quickly can save water and prevent more costly property damage down the line. With routine maintenance and insulation, your outdoor faucets should remain leak-free for years before needing replacement.
