Understanding Your Outdoor Spigot: Parts and Function
An outdoor spigot, also called a hose bib or faucet, is a water valve mounted on the exterior of your home. It serves as the connection point between your home's water supply and outdoor equipment like garden hoses, sprinklers, and pressure washers. Understanding the basic components helps you identify problems and communicate clearly when seeking professional service.

The main body of a spigot contains several key parts working together. The handle or knob controls water flow by opening and closing an internal valve. Behind the handle sits the packing nut, a small hexagonal fitting that prevents water from leaking around the handle stem. The stem itself is the shaft that moves up and down when you turn the handle, controlling whether water passes through. At the end of the spigot is the outlet, where water exits toward your hose connection.
Inside the valve sits a washer, typically made of rubber or silicone. This washer creates a seal that stops water flow when the handle is turned off. Over time, this washer wears out, leading to drips. The seat is the surface where the washer makes contact—corrosion or damage to this seat can prevent a complete seal even with a new washer.
Most outdoor spigots are frost-proof models, especially in colder climates. These spigots have a longer stem that extends inside your home's wall, where temperatures remain above freezing. When you turn off the handle, the internal valve closes at a point deep inside the wall rather than at the exterior outlet. This design prevents water from freezing in the exposed part of the spigot.
The packing nut surrounds the stem where it exits the spigot body. If this nut loosens, water leaks around the stem rather than through the spout. A leaking stem looks different from a dripping outlet—water appears near the handle rather than at the tip where you attach your hose.
Practical Takeaway: Before attempting any repair, identify which type of leak you have. A drip at the spout tip suggests a worn washer. Water around the handle points to a loose packing nut. Identifying the leak location helps you determine whether the repair is something you can handle or requires professional attention.
Identifying Common Spigot Problems and Their Causes
Most outdoor spigot problems fall into a few common categories. Recognizing the signs early can prevent water waste and potential damage to your home's foundation or landscaping. A single dripping spigot can waste approximately 3,000 gallons of water per year, according to the Environmental Protection Agency. This translates to increased water bills and unnecessary resource consumption.

A steady drip at the spout outlet is the most common issue. This occurs when the internal washer deteriorates and no longer creates a complete seal. Even when the handle is fully turned off, water continues to fall slowly from the outlet. In most cases, this indicates the washer needs replacement. Frost-proof spigots occasionally drip because mineral deposits accumulate on the washer seat, preventing a tight seal.
Water leaking around the handle stem suggests a different problem. The packing nut has likely loosened over time due to temperature fluctuations and normal wear. Tightening this nut can stop the leak without requiring internal repairs. If tightening doesn't work, the packing material inside has deteriorated and needs replacement.
Reduced water flow occurs when mineral buildup blocks the spigot opening. This happens more frequently in areas with hard water—water containing high levels of calcium and magnesium. The deposits accumulate around the aerator or screen at the spout tip, restricting flow. Cleaning or replacing these components usually restores normal water pressure.
Frozen spigots that won't turn or release water indicate ice has formed inside the valve. This typically happens in frost-proof spigots when water was left in the hose over winter or when the drain valve inside the wall became blocked. Prevention is far more effective than attempting to thaw a frozen spigot, as heating methods can damage internal components.
Cracks in the spigot body occur from freeze damage or physical impact. A cracked spigot cannot be repaired and requires complete replacement. You may notice water seeping from the body rather than from the outlet or handle area. This is one of the few spigot problems that has no repair solution.
Practical Takeaway: Keep a maintenance log noting when your spigot starts dripping or showing signs of reduced flow. Early intervention prevents small problems from becoming expensive replacements. A dripping spigot costs far less to fix than replacing a cracked one or dealing with water damage to your home's exterior.
Step-by-Step Washer Replacement Process
Replacing a worn washer addresses most dripping spigot problems. This repair requires only basic tools and takes about 30 minutes. Before starting, turn off the water supply to your spigot if possible. Most homes have shut-off valves near the outdoor spigot connection inside the basement or crawlspace. If your spigot has no individual shut-off valve, you may need to turn off the main water supply to your entire home.

Gather these materials before beginning: an adjustable wrench or two crescent wrenches, a flathead screwdriver, a small container to catch water, and replacement washers in common sizes (typically 15/16-inch or 7/8-inch). Hardware stores sell universal washer kits for outdoor spigots at minimal cost. Having extra washers on hand prevents multiple trips to the store if the first size doesn't fit.
Start by removing the handle. Most handles have a set screw on the underside that holds them to the stem. Using a flathead screwdriver, turn this screw counterclockwise until it loosens. Some handles slip straight off once the screw is removed, while others require gentle rocking to pull free. Set the handle somewhere safe—you don't want to lose this small part.
Next, use your wrench to loosen the packing nut, the hexagonal fitting directly beneath where the handle was attached. Turn counterclockwise until this nut comes free. You may see a small amount of water drip out—this is normal. Some spigots have a second smaller nut below this; if present, remove it as well.
Carefully pull the stem straight out of the spigot body. Turn it slowly while pulling to avoid damaging internal threads. As the stem emerges, you'll see the washer attached to its end, held in place by a small brass screw. Using your flathead screwdriver, turn this screw counterclockwise to remove it. The old washer will likely appear hardened, cracked, or visibly deteriorated.
Examine the stem end where the washer sits. If you see pitting or corrosion, you may want to use fine sandpaper to smooth this surface. A damaged seat prevents a new washer from sealing properly. Look inside the spigot body where the stem comes out. If mineral deposits or corrosion appear, use a soft cloth to clean these surfaces.
Insert the new washer, ensuring it fits properly in the depression at the stem end. The washer should sit flat without tilting or bunching. Secure it with the small brass screw, turning clockwise until snug but not overly tight. Over-tightening can damage the new washer. Carefully push the stem back into the spigot body, turning slightly as you insert it to align the threads properly.
Once the stem is fully inserted, hand-tighten the packing nut, then use your wrench to snug it up. Turn the handle back onto the stem and tighten its set screw. Turn the water supply back on and test your spigot. The leak should stop completely. If water still drips, turn off the water and check that your washer seated properly.
Practical Takeaway: Keep notes on your washer size and spigot model for future reference. Take a photo of the old washer next to a coin for size comparison. This makes future repairs faster and ensures you purchase the correct replacement parts without guessing.
