Dealing with a leaky outdoor faucet can be a frustrating experience, but with the right knowledge and tools, it is often an easy fix. Here is a comprehensive guide on how to diagnose and repair a leaky outdoor faucet to stop the dripping for good.
Symptoms of a Leaky Outdoor Faucet
Here are some common signs that your outdoor faucet may be leaking:
- Dripping water when the faucet is turned off
- Pooling water at the base of the faucet
- Higher than normal water bills
- Low water pressure
- Rust stains on the faucet exterior
If you notice any of these issues, it likely indicates a problem with the faucet that needs repair. The most obvious symptom is dripping water, but other signs can point to a leak too.
Causes of a Leaky Outdoor Faucet
There are several potential causes of a leaky outdoor faucet:
Worn Washers
The rubber washers inside the faucet handle and spout aperture wear out over time. This allows water to drip even when the faucet is turned off. Replacing these washers is the most common leaky faucet fix.
Damaged Valve Seats
The valve seats inside the faucet may be corroded, cracked, or ill-fitting. This damages the seal and enables water to leak through. Valve seats can often be repaired, but may need replacement.
Frozen Pipes
In cold climates, frozen pipes can cause outdoor faucet leaks. The expansion of water as it freezes puts pressure on joints and seals. Once thawed, they often leak.
Loose Connections
Loose connections between supply lines, fittings, and the faucet may cause drips. Tightening these connections can usually fix this.
How to Stop an Outdoor Faucet Leak
Follow these steps to stop an outdoor faucet from leaking:
Step 1: Turn Off Water Supply
Locate the shutoff valve for the outdoor faucet and turn off the water supply. This is usually an indoor valve that isolates the outdoor lines. This stops the flow while you diagnose the leak.
Step 2: Inspect Faucet Exterior
Examine the exterior of the faucet first. Look for cracks, corrosion, loose fittings or other exterior issues that could cause drips. Tighten any loose connections.
Step 3: Remove Faucet Handle
Take off the faucet handle so you can inspect the interior. This usually involves unscrewing a securing screw or cap and then pulling the handle up and off.
Step 4: Check Washers
Examine any washers inside the faucet handle and spout. Look for wear, tear or deformation. Replace any damaged washers with exact replacements.
Step 5: Inspect Valve Seats
Check valve seats inside the faucet body for corrosion, cracks or damage. You may be able to smooth them with sandpaper or otherwise repair them. Replace if needed.
Step 6: Reassemble Faucet
Put the faucet back together with the new washers and/or valve seats if replaced. Make sure all connections are tight.
Step 7: Turn Water Back On
Turn the water supply back on slowly. Check for any drips or leaks as pressure builds. Tighten any areas that still leak.
Step 8: Insulate Faucet
For exterior faucets prone to freezing, insulate with foam covers or heat tape. This helps prevent freeze damage.
With a few basic tools and replacement parts, you can often fix a leaky outdoor faucet yourself. Calling a plumber is recommended for more complex leaks or underlying issues. Acting quickly can help prevent further water damage and wasted water.
FAQs About Fixing a Leaky Outdoor Faucet
How do I know if my outdoor faucet needs new washers?
If the faucet leaks even when fully turned off, worn washers are often the culprit. Any dripping with the handle completely closed indicates washer replacement is needed.
What are outdoor faucet washers made of?
Most washers inside outdoor faucets are made from rubber or neoprene materials. Make sure to use weather-resistant washer replacements made for outdoor use.
What size are most outdoor faucet washers?
Standard outdoor faucet washers are typically 1/2 inch or 3/4 inch. Bring the old washer with you to get an exact size match when purchasing a replacement.
How do I remove an outdoor faucet handle?
There is usually a set screw or cap on the handle that needs to be loosened with an Allen wrench or screwdriver. This allows you to pull up the handle and access the interior.
Should I replace both hot and cold washers?
It’s recommended to replace both the rubber washers for hot and cold water when one side leaks. The other washer likely has similar wear since they’re the same age.
Can I use plumbers putty on an outdoor faucet?
No, plumber’s putty is not recommended for outdoor faucets. Instead, use pipe thread sealant tape or outdoor-rated silicone to seal threaded joints on an exterior faucet.
How do I stop my outdoor faucet from freezing in winter?
Use foam insulated covers or electrical heat tape. Draining the faucet before the first freeze also helps prevent burst pipes and ice blockages when not in use.
What if replacing washers doesn’t fix my leaky outdoor faucet?
If new washers don’t stop the drip, the issue may be with the valve seats or other interior components. A full faucet rebuild or replacement may be needed in that case.
Conclusion
Fixing a leaky outdoor spigot is usually a quick and inexpensive DIY project. In most cases, worn rubber washers are the culprit and replacing them stops the drip. For persistent leaks, inspecting the valve seats and fittings can help diagnose the problem. Make sure to turn off the water supply before taking a faucet apart to make the repair process easier. With the right diagnosis and parts, you can repair an outdoor faucet leak and prevent wasted water and damage.
