If you notice water dripping or leaking from the small hole at the base of your outdoor faucet, known as the “weep hole”, this indicates an issue with the faucet’s stem that needs to be addressed. The weep hole is designed to allow water to drain out in the event of internal leakage, preventing damage from water collecting inside the faucet body. While a small leak from the weep hole now and then is normal, a steady drip likely means repairs are required.

What causes an outdoor faucet to leak from the weep hole?
There are a few common reasons why water may leak from the weep hole in your outdoor faucet stem:
- Worn out rubber washers – The rubber washers around the faucet stem wear out over time. As they degrade, they no longer form a watertight seal, allowing water to leak through.
- Damaged or corroded stem – Mineral deposits, corrosion, and general wear can damage the faucet stem, leading to leaks around the stem seals.
- Too much pressure – High water pressure can push past worn washers and seals, forcing water out through the weep hole.
- Freezing temperatures – If water freezes inside the faucet body, it can damage washers, seals, and even the stem itself.
The most common cause is worn out rubber washers that need replacement. But corrosion, mineral buildup, and high water pressure can also play a role by damaging seals over time.
How to fix a leaky outdoor faucet weep hole
Replacing the faucet’s rubber washers is usually the easiest fix for a leaky weep hole. Here are the basic steps:
- Turn off the water supply to the outdoor faucet and open the faucet to release pressure.
- Unscrew the faucet stem with an adjustable wrench or other suitable tool.
- Remove the stem and check the condition of the rubber washers. Replace any washers that are cracked, worn out, or flattened.
- Apply plumber’s grease to the new washers and reassemble the faucet stem.
- Tighten the packing nut over the stem. Don’t overtighten, as this can damage the rubber.
- Turn the water back on slowly and check for leaks. Tighten the packing nut gently if needed.
Replacing the washers is often an easy DIY fix that takes less than 30 minutes. Make sure to shut off the water supply first! If the leak persists after replacing washers, there may be an issue with the stem or other internal seals that requires a full replacement of the faucet.
When to call a plumber
While minor weep hole leaks often can be repaired yourself, there are times to call in a professional plumber:
- The leak continues after replacing washers
- There is corrosion or mineral buildup on the stem
- You are unable to fully turn the faucet off
- There are signs of damage to the faucet body or stem
- You do not feel comfortable doing the repair yourself
A licensed plumber has the skills and tools to fully diagnose the cause of persistent leaks, assess any stem and valve damage, and perform necessary repairs or full faucet replacement if needed. They can also adjust water pressure and check for upstream issues that may be contributing to leaks.
Tips for preventing outdoor faucet leaks
Here are some tips to help minimize leaks and keep your outdoor faucets in good working order:
- Inspect washers and seals annually before winter and replace as needed.
- Make sure the faucet is fully turned off when not in use.
- Install freeze-proof faucets if you live in areas with frequent deep freezes.
- Insulate outdoor pipes and faucets before winter.
- Have a plumber install a backflow preventer valve if needed.
- Avoid using spray attachments that can damage washers.
- Repair any drips right away to prevent worse damage over time.
Performing regular maintenance and promptly repairing any leaks can significantly extend the life of your outdoor faucets and prevent costly damages from occurring down the line.
When to replace the entire outdoor faucet
In some cases, fixing a leaky outdoor faucet is no longer feasible due to extensive wear and tear. Signs it may be time for full replacement include:
- The faucet body is badly corroded or cracked
- Leaking cannot be stopped after multiple washer replacements
- The stem is difficult or impossible to remove
- Water flow is very weak even after repairs
- Valves and seals are heavily calcified
- Frequent leaks keep occurring and repairs never hold
Replacing the entire faucet is often the most cost-effective solution when the unit is generally beyond repair. A new faucet also brings improved features like frost-free designs, more durable materials, anti-siphon protection, and higher flow rates for better water pressure.
Cost to replace an outdoor faucet
The costs to fully replace an outdoor faucet can range from $80-$250 or more, with the average around $150 for parts and labor:
| Outdoor faucet replacement cost | Price range |
|---|---|
| Faucet unit | $35 – $150 |
| Shut-off valves | $5 – $25 per valve |
| Connectors & fittings | $10 – $50 total |
| Labor & installation | $40 – $100 per hour |
High-end faucets with special finishes, metal construction, and convenience features like built-in locks can run over $200. The total cost also depends on if extensions, adapters, or additional shut-off valves are needed. Hiring a plumber for installation tends to add $50-$100 or more to the overall project cost.
Conclusion
A leak from the weep hole in an outdoor faucet stem often indicates worn out internal washers or seals. Replacing the rubber washers is typically an easy fix, but persistent leaks or extensive corrosion may require replacing the entire faucet. Annual maintenance and prompt repair of any drips can help prevent costly faucet repairs down the road. If DIY repairs don’t solve the issue, consulting a professional plumber can be worthwhile to fully resolve persistent weep hole leaks.
