This article explores the causes of outdoor faucets that leak when turned on and possible fixes. Loose connections, worn-out washers, and damaged o-rings are typical sources of leaks.
Corrosion, frozen pipes, and excessive water pressure are additional conditions that might cause leaks.
Replace the damaged component or tighten any loose connections to repair a leaky outdoor faucet. It could be required in some circumstances to hire a qualified plumber to fix the faucet. Homeowners can avoid water waste and possibly expensive water damage by being aware of the typical causes of outdoor faucet leaks and how to correct them.
From tiny leaks to catastrophic problems that could seriously harm your house, outdoor faucet troubles can range in severity. Leaks, low water pressure, and freezing over the winter are a few of the most typical issues.
Numerous things, including worn-out washers, harmed pipes, or incorrect installation, can contribute to these issues. For your plumbing system to last as long as possible and to avoid further damage, it’s critical to handle outdoor faucet issues as soon as they appear.
Regular upkeep and inspections can aid in avoiding the emergence of these issues altogether.
A home with two leaky exterior faucets wastes 57,600 drops of water each day at a slow drip rate of 20 drips per minute. A leaky spigot wastes 5 gallons of water daily, and leaks from outdoor faucets waste 1,851 gallons of water in a single year.
Tools required for outdoor faucet repair:
Materials required:
If you have a leaking vacuum breaker, it must be examined and fixed right now. To gain access to the vacuum breaker parts, open the vacuum breaker cap.
Using two screwdrivers, pry and remove the cap to reveal the contents. Next, replace the components of the vacuum breaker. Plumbing supply stores carry these.
After finishing, carefully put together your outside faucet and switch on the water.
Is the leak still there? Yes? Then the faucet is damaged. You’ll need to swap out the entire unit with a new one in order to halt the leakage.
First, shut off the water supply to the outdoor spigot using the indoor shutoff valve. Once the water is off, open the outdoor spigot fully to drain remaining water.
Grab a wrench and remove the handle by unscrewing the small screw on top. The stem assembly will now be accessible – unscrew it counterclockwise to remove. You’ll see rubber washers and O-rings which are likely worn out and causing the leak.
Take the old parts to the hardware store to find exact replacements for the washers and O-rings. While there, pick up plumber’s grease. Clean the valve seat inside the bib with a wire brush to remove mineral deposits or debris.
Apply plumber’s grease to the new washers and O-rings, then reassemble the stem in reverse order. Make sure all parts are properly aligned. Hand-tighten the packing nut behind the handle, then give it a quarter turn with the wrench.
Turn the water back on and test for leaks. If it still leaks, the valve seat may be damaged and you’ll need to replace the entire hose bib assembly or call a plumber.
For future prevention, always turn the handle gently to avoid damaging washers and remove hoses during freezing weather.
Immediately turn off the main water supply valve. Locate the leak source – check walls, ceiling, and floor near the spigot pipe. If there’s significant water damage, contact a plumber right away.
For minor leaks: Remove the interior trim plate and inspect the pipe joint. Look for loose connections, corrosion, or pipe cracks. Tighten any loose fittings with a pipe wrench. If the pipe is cracked or severely corroded, it needs replacement.
Signs of a serious issue requiring professional help: water stains spreading on walls/ceiling, mold growth, musty smell, or sound of running water when spigot is off.

Replace when:
A washer replacement typically costs $2-5 and takes 15 minutes. Full faucet replacement costs $20-50 but prevents future leaks.
If you merely need to tighten or replace a loose washer, fixing a leaking outdoor faucet can be done for very little or even for free. The price of changing each component, however, can add up if you decide to completely replace the outside faucet.
A new brass hose bib with a shutoff valve can cost over $200, while replacing a spigot costs about $100. An outdoor faucet can be fixed or replaced for an average price of $50 to $300. You’ll probably save a lot of money if you can handle it yourself, because a hose bib alone costs $5 to $10.
When a faucet leaks at the base when it is turned on, it is typically because of an O-ring or cartridge inside the faucet that is worn out or damaged. The cartridge regulates the water flow, while the O-ring, a tiny rubber ring, serves to seal off the faucet’s base.
When the faucet is turned on, water may leak out at the base due to these components wearing out or becoming broken over time. It’s preferable to contact a qualified plumber for the repair because replacing the O-ring or cartridge is frequently required to resolve the problem.
If the rubber washer inside the faucet is worn out or damaged, or if the connection between the hose and the faucet is slack, an outside faucet starts leaking when a hose is attached.
When the hose is connected, the water pressure goes up, which accelerates washer wear. It may be possible to fix a leaky faucet by replacing the washer or tightening the connection.
